Tree Trimming: The Different Tools That Are Used For The Job

!: Tree Trimming: The Different Tools That Are Used For The Job

The best time for tree trimming varies from tree species to another. In general, spring up to the early part of summer is considered as the best time for this type of tree service. When tree trimming and shaping is done, it's really important that the right tools are used in order to prevent injuries both to the trees and the persons doing the job. In addition, using the proper tools will also help ensure that the tree ends up looking more aesthetically pleasing instead of the other way around.

There are different kinds of tree trimming tools available in the market today. Each one of them is designed for cutting different trees that have different sizes and varying heights.

The Tools Used For Trimming Trees

The process of trimming trees may sound really simple but it's not. Certain guidelines need to be followed in order to ensure the safe cutting of the trees' branches. Overall, doing the trimming job at the right place and at the right time using the proper tools will not only enhance the look of the canopy shape but will also help to promote the growth of the trees while protecting them against diseases. Below are the tools used for the job.

Mechanical Saw: A lot of gardeners nowadays own a mechanical saw, which they use for performing basic garden maintenance procedures. This is a manually-operated tool, which can also be used for trimming trees.

Chain Saw: There are two types of chain saws namely those that run on gas and those that run on electric power. Between the two, gas powered chain saws are more popularly used when it comes to shaping trees. They can be used to trim any kind of tree.

Pole Tree Pruner: This is one of the best tools to use if you're going to trim a tree from the ground. With this tool, you can trim small to medium-sized branches even without using a ladder. A pole tree pruner is made of 3 parts namely a saw, rope, and an adjustable handle.

Lopper: This is well-suited for trimming small trees specifically those that range from 2 to 3 inches in diameter. This is also called the lopper shear or pruner lopper. This comes with a long handle and blade, which resembles that of a scissor.

Ladder: This is important to have since most of trees' branches are too high to reach without using this tool. If you want something really good, an extension ladder is a good choice. You can use this to trim both small and large trees.

Aside from the ones that I have mentioned above, there are also other types of tools that are more sophisticated such as wood chippers. Regardless of the kind of tool that you use, it's important that you use it with precaution by following the manufacturer's guidelines.

What's Up (or Down) With Texas Electricity Rates?

!: What's Up (or Down) With Texas Electricity Rates?

Since deregulation began within the state of Texas at the turn of the millennium, Texans have learned as much or more about how electricity works than people in any other place in the world. Some of the lessons learned were great for the foundation of understanding how the market would affect customers in principle. Some of the lessons learned could be considered more symptomatic of the times than as part of the bedrock of how the market will always function.

One of the lessons that we've all learned and been taught to expect is that electricity rates will always go up, sometimes way up, during the summer heat season. The notion of the rate increasing and the bills increasing seems almost intuitive. And frankly, why wouldn't it? Since the days before deregulation, Reliant's rates jumped each summer from May - November.

Was the seasonal rate increase a product of additional expenses during that period? Greed? State mandate?

The reality of it is that it was almost exclusively a product of the companies incurring additional expenses in the summer time. But shouldn't the cost of generating electricity more or less remain constant between the winter and the summer? The simple answer is usually "no".

Why?

Given that it is much hotter in the summer within the state of Texas, more air conditioners are run, for both homes and businesses. It takes more A/C power to heat the same room at the same temperature as the outside heats up, too. The A/Cs have to run longer and later to keep homes and businesses cooled off. As more electricity is needed on a household by household basis, and a business by business basis, more electricity has to be generated and placed onto the state's electricity grid. As that happens, more electricity generators need to be run to keep up with demand than in other times of the year. The generators that are forced to come on line during this period are usually more expensive to run for the provider - which is why they're not the first generators online each day. When the generation becomes more expensive, the price increase is spread down the supply chain. The Retail Electricity Provider has to pay more and the customer, ultimately, has to pay more as well.

That makes it seem as though electricity rate increases really should be part and parcel to each year's heat season. But should this always be the case? Perhaps not.

Often times, experts will speak about this cause and effect relationship and then divert on a tangent in regard to natural gas prices. Natural gas prices affect the price of electricity in a place like Texas because many of the less-used generators run on natural gas as fuel for generating the electricity. Natural gas, as opposed to coal, nuclear, or various other products also used to generate electricity within the grid, is a much more expensive and volatile product on the price side. As a for instance, last summer saw record electricity prices that correlated almost symmetrically with record natural gas prices. Heading into this summer, however, we find that as a market, natural gas prices have basically collapsed to points that we haven't seen in more than half a decade. With that as a given, can't we basically assume that prices won't rise significantly? Yes, as part of the equation, as long as natural gas prices are lower, electricity prices will be lower. This is a foundational principle to how the market functions.

But that's not the entirety of the story. Another variable within the equation is often ignored and typically, by the average trader and forecaster within the Texas market, dismissed as relevant because it is assumed to be a relative constant, is market demand for electricity. And why wouldn't it be? It's always a hot summer in Texas, right? Homes will always need to be cooled, right? Businesses will always be booming and consuming more and more energy to create more products, right?

Well, the truth to one of those questions is, it's often a hot summer in Texas, so that assumption is ok.

On the question about home being cooled, well, homes always do need to be cooled, too. And so do apartments. But what happens if the mix of homes using electricity versus apartments using electricity ever dramatically shifts? Can less people living in homes drive the overall demand for electricity within the market down? Let's think about it.

On average, home dwellers use about 1.5 times the amount of energy that is used by apartment dwellers. Overall, the residential demand within the Texas grid, in aggregate, is roughly 40% of the total electricity used. If the mix of home dwellers to apartment dwellers is historically 55% to 45% of the population within Texas, this would indicate that almost 70% of the residential electricity demand traditionally comes from home dwellers. That also means that home dwellers generally impact about 27-30% of the total demand within the Texas electricity market as whole. Let's assume the 27-30% consumed by home dwellers within the market works for the summer, which is the most likely.

Now consider the possibility that a migration within the marketplace occurs from people living in homes to people living in apartments. In recessionary times, this is usually a reality and this recession is no different. Apartment communities are nearing capacity throughout Houston and Dallas, just as foreclosures rise and people move out of homes after layoffs and payroll decreases as an act of reducing expenses. Publicly available data on this is scarce, but we can use some of the information provided recently by http://HAR.com, which covers Houston real estate sales. This shows that more than 30% less new homes were sold in the Houston area over the first quarter this year and last. They've also released data disclosing that roughly 25% less existing homes were sold in the same time period. Meanwhile, foreclosure rates continue to increase, as do apartment occupancy rate. Extrapolate that across to Dallas as well and the numbers and demand within the overall market starts to look considerably different than years past. Specifically, a shift of that nature on the residential side of electricity usage translates into a relevant decrease in overall market demand for usage. The market clearing price for electricity within the market is based on what the last electricity generator selling electricity to the market has to charge to cover its costs. If the more expensive generators are impacted by that "demand destruction", and given that since those generators are the last to be used, they are impacted, the prices are not going to see the potential exponential increase that those generators would create.

That portrays what role something as simple as a shift in dwelling type for Texas residents could do to the market.

What happens if demand destruction also exists on the business side of the market? Are businesses using less electricity today than they were a year ago in Texas?

The answer is that if demand destruction occurs on the business side, the need for excess, more expensive electricity capacity within the market would see an even sharper decrease than what we looked at on the residential end. Business usage is demonstrably higher than residential usage within the Texas market, as whole.

So are businesses using less electricity today than this time last year? Well, yes. For one, any business that has gone out of business is using less, to be sure. It is a simple fact that the market is contracting right now, which means we're experiencing negative growth today. A classic and directly related example of this situation is what's occurring on the Houston Ship Channel. As a group, this set of businesses uses more electricity than any other specific group of businesses within the state. They have to use enormous amounts of electricity to create the products, such as plastics and tires for automobiles, that they ship throughout the rest of the world. When orders for new products weaken or dry up, these businesses are forced to take action, such as extended shut downs or flat out closures of production lines or the businesses themselves. These events have occurred within the last 12 months, and they've happened across multiple plants with few plants being unscathed.

With business usage for electricity on the whole representing a net decline within the market, coupled with less residential usage for the same reasons, demand destruction is a very real part of the overall prices reflected within the market at the beginning of this summer. If the demand remains depressed compared to the past 7+ years, this often dismissed potential variable within the equation for electricity prices to the public will continue to play a big role. The end result may be so significant that prices throughout the summer don't actually rise much at all, and could ultimately wind up lower at the end of the summer than when the heat season began. With that as a possibility, if not a probability, Texans can count on continuing to see some of the lowest electricity prices within the entire country for the duration of 2009. For every Texas resident within these recessionary times, that should be considered good news.

Riding the Rails in Rockhill Furnace, Pennsylvania

!: Riding the Rails in Rockhill Furnace, Pennsylvania

Tucked into the pocket of a pair of hundred-year-old railroad engineer coveralls, you are instantly returned to an era of vintage rail transportation here. Like triumphantly raised arms, two silver smokestacks proclaim their victory over time, which otherwise seems suspended by the sprawling, wooden, red-painted shop complex surrounding it, modified by not a single nail since it first rose from the ground. A cobweb of tracks, imbedded in the artery which divides the twin boroughs of Rockhill Furnace and Orbisonia, merges into three in front of the depot, which bears the latter's name, departure point for one of three daily, narrow-gauge, steam locomotive-pulled trains operating as the East Broad Top Railroad. The clang of a bell, rung across the street, indicates the arrival of a bright red trolley car from the opposite direction.

Tourists ride the rails today; coal miners rode them yesterday.

Cradled by Blacklog Mountain and both Saddleback and Sandy Ridges, the area, then undeveloped, beckoned prospectors with its natural resources, consisting of agricultural land, water, timber, coal, and iron, the Blacklog Creek both feeding and leading them to what would become its twin boroughs.

Initially serving as a Native American campsite and hunting ground, as evidenced by archeological traces found at Sandy Ridge, the area first took root in 1754 when land was purchased from Six Nations, and the first road, mimicking the original Indian path and fostering westward expansion of settlers, was created 33 yeas later, stretching between Burnt Cabins in the south and Huntingdon in the north.

Bedford Furnace, the area's first village, evolved from a trading post in 1760. Providing both a sense of location and permanence, it attracted the first white settler, George Erwin, who established a trading post in a log cabin, shipping goods over narrow, wilderness-tunneling trails and exchanging them with travelers and Native Americans alike.

Placing the initial pin into the map, the Bedford Furnace Company established a charcoal furnace in order to be able to produce iron in 1785, sparking growth in the Juniata Valley and serving as the first of many to eventually characterize it.

Rockhill Furnace Number 1, built in 1831 by Thomas Diven and William Morrison south of the town in Blacklog Narrows, replaced the smaller, original plant, while Winchester Furnace, the third such ironworks, rose a few hundred yards away.

Abandoned in 1850 after a less-than-prosperous reign, it was joined seven years later by furnace Number 1 when area deforestation depleted the timber necessary for iron smelting charcoal, although the Civil War once again-albeit temporarily-re-lit its fires.

A mortgage foreclosure preceded its purchase in 1867, but its resurrection now hinged upon a fuel source to feed it. The needed pot of gold at the end of the rainbow-or, in this case, on top of the rainbow-came in the form of coal discovered on Broad Top Mountain. What was now required was a method to transport it from its summit-located mines to the iron furnaces in the east.

East Broad Top Railroad:

During the early-1850s, Pennsylvania's Juniata Valley began to sprout rails.

The single track of Pennsylvania Central Railways, thread through the narrow mountain passes and along the Juniata River, connected Lewistown and Huntingdon, for the first time offering a non-aquatic, intrastate transportation alternative to the Public Work's Main Line Canal. The Pennsylvania Railroad's own all-rail line soon grew branches throughout the Allegheny Mountains, allowing it to penetrate hills and valleys in order to collect and haul the region's riches in the form of lumber and coal. Track laid between 1853 and 1854 enabled the Huntingdon and Broad Top Railway to surmount its very namesaked incline on the west side. But rail access remained a void on its east.

Although the necessary charter for such a rail line had been granted on April 16, 1856, several proposals-and 14 years-ensued before a group of Philadelphia businessmen, spurred by the Civil War's cry for additional track to move troops and supplies, collected the required capital to construct one, forming, with the aid of the still-born charter, the East Broad Top Railroad and Coal Company on July 3, 1871. It was decided, from the outset, to employ three-foot, narrow gauge track in order to reduce construction and operating costs and facilitate tighter turns.

The first track was put to bed on September 16 of the following year and its first locomotive, a 17.5-ton, wood-burning, narrow-gauge 2-6-0 built by the Baldwin Locomotive Works of Philadelphia and named the "Edward Roberts," was delivered a year after that.

Like a journey of time, track-laying could be measured by the calendar, the first 11 miles of it reaching Rockhill Furnace on August 30, 1873, ascending Sideling and Wrays Hills before arriving in Robertsdale the following year-all for the purpose of transporting coal and forestry products from Broad Top Mountain to Mount Union, its southern terminus, for transfer to standard-gauge Pennsylvania Railroad trains.

The original village of Rockhill Furnace, taking shape round the iron furnaces a half-mile from the current depot on the banks of Blacklog Creek, progressively expanded.

The fleet equally multiplied when three 26-ton Baldwin Consolidation engines were acquired between late-1873 and early-1874, the same year that the Robertsdale-mined coal was first rail-transported to Rockhill Furnace to fuel the blast furnaces now taken over by the newly-formed Rockhill Iron and Coal Company to ultimately produce pig iron.

As a town, Rockhill Furnace took initial form as a dual-stack iron furnace and collection of coke ovens, which expanded into the East Broad Top Railroad shop complex lining the Jordan Creek-a veritable pocket of self-sufficiency.

Occupying the farmland purchased for the complex and employing the original, still-existent stone farmhouse for its administrative offices, the soon-sprawling plant's gears were turned by means of its steam-powered overhead shafts and belts, with additional electricity and compressed air generated by its boiler plant, pumping current, like flowing blood, to its foundry and machine, car, and blacksmith shops. Its brick roundhouse, eventually encompassing eight stalls, facilitated alignment with the needed track, provided light locomotive maintenance, and served as a storage shed, while heavy repairs occurred in the machine shop. Commodities necessary for steam engine operation, including water, coal, and sand, were stored throughout the complex, which itself was capable of the locomotive repair and maintenance functions themselves, as well as rolling stock manufacture and the production of forgings, castings, and machine parts for both the railroad and the mines it accessed.

The yard's wye, formed by track from Mount Union and crossing Meadow Street (Pennsylvania Route 994) just past the Orbisonia depot, facilitated intra-complex car movement, storage positioning, and train configuration, providing access to either Alvan or the Shade Gap Branch, depending upon car orientation.

Indeed, the shop complex served as one of many links in a chain, none of which could have existed without the other, inclusive of the area's natural resources giving rise to the iron smelting industry, the railroad needed to transport the coal to fuel it, the shops to manufacture and maintain its equipment, and the town arising to support the workforce which turned its gears.

Its fleet initially encompassed two passenger coaches, two baggage cars, and 176 freight and coal hopper cars.

From the mainline, which extended from Robertsdale to Woodvale in 1891 and Alvan in 1916, spur tracks spread like arteries from a central vein as additional mines were bored, resulting in the Shade Gap, Shade Valley, Booher Mine, Rocky Ridge, Number 7 and Number 8, Coles Valley, and NARCO branches, and the Shirleysburg clay spur.

With progressive expansion and prosperity, the East Broad Top Railroad began to carry passengers over and above the standard miners, coal, and freight for whom and for which it had been conceived.

The beginning of the 20th century signaled the railroad's infrastructure modernization program. Iron rails, for example, were replaced by steel ones. Wood was equally swapped for steel on trestles and bridges, and the durable metal for the first time formed its freight cars.

In 1926, coal-in addition to iron ore, quartzite ganister rock, forest products, and other miscellany-constituted 80 percent of its freight, exceeding 26 million ton-miles alone.

According to East Broad Top Railroad Timetable Number 53, effective Monday, September 29, 1930, it covered the 33-mile main line route from Mount Union to Alvan in one hour, 45 minutes, one southbound run departing at 0920 and arriving at 1105 via Allenton, Adams, Aughwick, Pump Station, Shirleysburg, Orbisonia, Pogue, Three Springs, Saltillo, Fairview, Kimmel, Coles, Rocky Ridge, Wrays Hill, Cooks, Robertsdale, and Woodvale.

Like everything in life, however, the railroad experienced both peaks and troughs. When the depression sunk its teeth into its profits, it was reorganized, simply, as the Rockhill Coal Company, and J. William Wetter assumed the presidency of both the iron furnace and the railroad which fed it.

Exerting its demands for commodities, however, World War II temporarily re-lit the fires in its furnaces, and strip-mining joined its list of coal and ganister rock extractions for the first time.

Inevitably, with the iron supply dwindling and coal the only commodity left to haul, the end of the line-literally-loomed ahead. Passenger rail services from Mount Union to Woodvale, initially curtailed from the two daily, Monday-to-Saturday round-trips, to a single one, were altogether discontinued on August 15, 1954, leaving coal as its sole, and increasingly unprofitable, type of freight. Mount Union brick plants, converting from coal to natural gas, no longer needed it for their own viability, while the proliferation of rail-replacing roads hammered the final anvil into the line. Mail, now transferred to truck transport, obviated the need for the post office contract.

The Rockhill Coal Company terminated its coal shipment requirements on March 31 and the East Broad Top Railroad's raison d'être essentially ended.

The last service, a round-trip from Rockhill Furnace to Mount Union via Saltillo and operated by 161,000-pound locomotive Number 17-a Baldwin 2-8-2 built in 1918-occurred on April 6, 1956, while all common carrier operations mimicked the event a little less than a month later, on May 1.

Stretching throughout the area, from Mount Union and climbing Broad Top Mountain on its east side, its mainline track network, along with its numerous, initially-intact branch lines, appeared like the cobwebs clinging to once-useful pieces of history, but now relegated to relics, their only associated movement, albeit in painstakingly slow form, being the weeds and grasses which sprouted between their cross-ties until they camouflaged them.

Not far behind was a second onslaught-in the form of the Kovalchick Salvage Company of Indiana, Pennsylvania--which had purchased the entire system, including its locomotives, cars, stations, shops, buildings, company houses, rights-of-way, and the land from which the once-precious coal commodity had been removed.

Four years passed. A few branch lines were uprooted. A handful of cars was sold to rail fans who insisted on owning a tangible piece of history. The weeds continued to aggressively attack and conquer the tracks. But, strangely, the dismantling company did not.

Indeed, instead of eradicating this piece of narrow gauge, steam railroad and coal mining history from the stage where it had been enacted, Nick Kovalchick, president of his company, became preservationist of it, rising from salvager to savior.

The East Broad Top Railroad's first re-purposed spark was lit by Orbisonia's one-week bicentennial celebration, whose cornerstone was the very rail line which had given birth to it, perhaps reflecting an act of creation, in which nothing truly dies.

Replacing tourists with coal, the trains would once again ply the tracks, offering return-to-history excursions. Cleared of underbrush, and given the necessary repairs, they once again supported railroad life when locomotive Number 12, a 1911 2-8-2 Baldwin, was christened with ginger ale by Kovalchick's daughter, Millie, on August 13, 1960.

Pulling two converted, open-air and four passenger coaches over the hitherto 3.5 miles of resurrected rail, it chugged, belched, and hissed black smoke and white steam, returning to the natural element for which it had been designed, as far as Colgate Grove. Because a wye had not been remedially installed until later, locomotive Number 15, having followed the proud, narrow gauge chain, pulled it back to the Orbisonia station.

Instead of departing history, the railroad, now under command of new president, Nick Kovalchick, has been returning to it ever since.

Designated a Registered National Historic Landmark by the United States Department of Interior in 1964, it is both the oldest-and oldest still-operating-narrow gauge railroad east of the Rocky Mountains, and today ranks as one of the "top tucks" into the preserved pockets of narrow gauge steam railroad history.

Tourists and locals alike retrace the bicentennial path, now stretching five miles, on one of three round-trip weekend excursion trains during May, June, and September; on Thursday-to-Sunday frequencies from July to mid-August; and during three-day, Friday-to-Sunday periods in October, covering the ten miles during 70-minute runs, ten minutes of which constitute a pause in Colgate Grove. Special and theme trains are offered on Mother's Day, Independence Day (accompanied by appropriate fireworks), Civil War weekends, on Labor Day, during the fall foliage season, on Halloween, and on Polar Express trips in December. Children-applicable trains are pulled by Thomas the Tank engines.

Although some 25 different steam locomotives plied the East Broad Top Railroad's tracks throughout its history, eight-comprised of six narrow gauge 2-8-2s and two standard gauge 0-6-0s-remain today, one of which is stored at the Whitewater Valley Railroad in Indiana. Most of the others continue to occupy their original residences-the roundhouse in the Rockhill Furnace shop complex.

The Number 3, a Baldwin standard gauge 0-6-0 built in 1923, was restricted to operations in the Mount Union switching yard and at the coal cleaning plant. The last and most powerful of the type, it was retired in April of 1956 and is stored in the Mount Union engine house.

The Number 12, a Baldwin 2-8-2 constructed in 1911, was contrastively the first and smallest Mikado to have been acquired, capable of hauling up to 15 loaded hopper cars from the coals mines. It was last used in 2000.

Of the same class as its Number 12 predecessor, the Number 14, built in 1912, was the second narrow gauge locomotive to be acquired, featuring both increased weight and power.

Still greater capability was offered by the Number 15, constructed in 1914, to satisfy increasing demand, enabling it to pull up to 18 loaded hopper cars.

The first of three large Mikados, the Number 16 of 1916, introduced superheaters, piston valves, and a Southern gear valve. It was retired a year before the original East Broad Top Railroad discontinued service, in 1955.

The succeeding Number 17 became the only heavy Mikado to be provisioned for tourist train service, while the number 18, the last and largest in the fleet, was retired in 1956. Like the other two in its class, it could pull 22 loaded hopper cars.

Several passenger cars, all coated in dark green, also encompass its fleet.

Of the coaches the railroad purchased from the Boston, Revere Beach, and Lynn, and the Air Sable and Northwestern, a single coach, two combinations, and the president's car remained after the others were sold at the conclusion of the line's passenger service. Six freight cars were converted to this configuration to enable it to write its tourist train chapter.

Coach Number 8, for instance, hails from 1882 and was constructed by the Laconia Car Company before having been acquired by Boston, Revere Beach, and Lynn in 1916.

Combine cars 14 and 15 share the same lineage.

Parlor car 20, now serving as the East Broad Top's first class coach usually appendaged to the end of the train, had been constructed in 1882 by Billmeyer and Smalls and was subsequently acquired from Big Level and Kinzua in September of 1907 for use as Railroad President Robert Seibert's personal coach.

Several other types make up the fleet, including flat, box, baggage, freight, and track cars, motorcars, cabooses, and diesel locomotives.

Today's tourist trains continue to depart from the "Orbisonia" station, a wooden, two-story, clapboard depot located on the north side of Meadow Street, just beyond the crossing point from the shop complex. It served as the railroad's operating headquarters after it moved from its initial, Marble House residence on a ridge behind the shop buildings. According to Vagel Keller, of the Friends of East Broad Top-a 501.c.3 historical and preservation society-"the current Orbisonia station (is) located in the borough of Rockhill Furnace, while the namesake is one-forth of a mile east... The station at this place was originally known as 'Rockhill,' and in 1888 the village got a post office called 'Rockhill Furnace.' Apparently, this caused misrouting of mail intended for an older post office in Pennsylvania named 'Rockhill,' and at about the same time that the current station was being built in 1906, the US Postal Service asked the East Broad Top to rename the station to avoid confusion... Paradoxically, the re-named 'Orbisonia Station' hosted the Rockhill Furnace post office until shortly after the end of common carrier operations."

During its heyday, its waiting room was alive with train crews, clerks, and passengers. Today, it serves as a gift shop still sporting its original wire ticket window, and from here passengers file through the door to a wooden, boardwalk-type porch, serving as a "platform," to await the train beneath the later-added, full-length trackside canopy.

The actual journey, in a choice of open, coach, or first class cars, plies the original, three-foot-wide, narrow gauge track and passes Orbisonia, farms, and forests before pausing at Colgate Grove after negotiating the wye, location of the East Broad Top's Shirleysburg clay spur, whose track had been laid in 1918 and had stretched from the grove itself to the base of the fire clay quarry on Sandy Ridge. Short-lived, its rails were removed in 1927, and the current wye, employing part of its right-of-way and constructed in 1961, resolved the train turn-around obstacle encountered during the bicentennial celebration excursions.

Today's passengers can remain at the grove either during the two-hour interval until the next run or overnight, but, since it offers little more than a barbecue and a scatter of picnic tables, all food, drink, and gear must be self-provided.

The East Broad Top offers two educational, railroad era-immersive programs. The first, designated "Engineer for an Hour," allows the rider to step into the shoes of an engineer and fireman by riding in the cab of a steam locomotive during one of the regularly scheduled trips, operating the throttle, blowing the whistle, and shovel-replenishing the firebox with coal. The second, "High Iron University/Rail Camp," is a five-day program offered in conjunction with Altoona's Railroaders Memorial Museum, and provides an indepth look at operating a steam powered railroad.

Aside from the train trip, rides are also offered in speeder, M-3, and handcars.

Another immersive experience is a tour of the railroad's shop complex, which served as the heart of its operation. Seemingly immune to time's sweep, it appears exactly as it did a century ago. The silver smokestacks mark the location of the Babcock and Wilcox boilers, which provided the steam needed to run the belt-driven equipment, while the red-painted buildings consist of the blacksmith, car, machine, and carpentry shops, pattern house, foundry, and lumber shed.

According, again, to Vagel Keller, "Another persistent myth holds that the current shops and roundhouse were built to replace earlier structures destroyed by a fire in 1882...The fire myth is based on oral traditions that conflate a cyclonic windstorm in the fall of 1881, which blew down part of the roundhouse (surviving today as the four arched doorways on the eastern half of the present structure), and on a fire in the early 1900s, which destroyed the paint shop and adjacent boiler shop. The roundhouse you see today originated with the four eastern stalls in 1874, was expanded to six stalls by 1895, and to its present form after 1911. The current shop complex originated in 1882 after the superintendent of the railroad prevailed on the Board of Directors to authorize the purchase of machine tools. Like the roundhouse, the shops were expanded over the years, taking their present form by 1911."

Rockhill Trolley Museum:

Sharing the dual-gauge portion of the rails in the yard across from the East Broad Top depot, the Rockhill Trolley Museum, billing itself as "Pennsylvania's first operating" one, affords the visitor a second opportunity to sink himself into vintage transportation history, plying the track to cover distance while distancing himself from time.

Powered by 600 volts of direct current collected by a continuous, overhead copper wire by means of a sliding shoe positioned at the end of a pole, electric trolleys, like trains, run on tracks, each of their under-floor motors usually powering a pair of wheels. An electric motor-driven air compressor channels pressure to their brakes. Internally, conductors check tickets and collect fares.

Tracing their origins to horse-drawn cars, trolleys, in their earliest forms, were small, wooden, four-wheeled vehicles, providing inter-city transportation. Demand, paralleling metropolis growth, soon necessitated larger cars, later constructed of steel, for passenger, freight, and mail transport, and by 1918, the trolley transportation industry had become the country's fifth-largest. Pennsylvania alone was served by 116 such trolley lines, which covered more than 4,600 miles of track.

But, as cities stretched, like taffy, into suburbs and were increasingly accessed by roadways, need for this transportation system declined, leaving only Philadelphia and Pittsburgh to run their lines after 1960, when Johnstown became the last small urban area to cease using its own.

Because it offers an inexpensive, pollution-free alternative to inner-city transportation, some existing track and related system components have been restored, which could be considered a budding stage of resurgence, modern cars or light-rail vehicles once again crisscrossing streets, intermixed with individual car and bus traffic.

This important trolley history can be experienced at the Rockhill Trolley Museum, which thus offers a second, rail-based transportation focus to Rockhill Furnace. Established in 1960, it acquired its first trolley car, the "Johnstown" Number 311, from its namesaked city. Built by the Wason Manufacturing Company of Springfield, Massachusetts, in 1922, it initially served in Bangor, Maine, before being sold to the Johnstown Traction Company, with which it performed a similar role in the Flood City until it was retired 19 years later, on June 11. As the first such car to operate within any Pennsylvania trolley museum track network, it continues to do so more than four decades later.

It is now one of many in the collection emanating form such Pennsylvania cities as Johnstown itself, York, Harrisburg, Scranton, and Philadelphia, and is part of its larger fleet of 35 in-service and under-restoration city and suburban, interurban, rapid transit, and maintenance-of-way cars.

York Car Number 163 is one of them. Constructed in 1924 by the J. G. Brill Car Company of Philadelphia, and constituting the museum's most extensively restored example, the trolley was one of five with curved sides operated by York Railways. Subsequently used as a summer home positioned just north of the city on the Conewago Creek, before being thrust from its foundation by Hurricane Agnes in 1972, it was subsequently donated to the museum. Now a collection of hybrid parts, including wheels and motors from Japan, seats from Chicago, and cane coverings from China, it became the world's only-operable example from York after the equivalent of 17 years of volunteer restoration.

Oporto Car Number 172 is an example of a smaller, single-axle car. Built and used by the Sociedades do Transportes Colectivos do Porto, or S.T.C.P., in 1929, the extensively brake-equipped vehicle, comprised of air, hand, and dynamic systems, was well suited to the Portuguese hilly city.

Ship-transported across the Atlantic and then road-conveyed from Philadelphia on a highway trailer, it immediately operated tourist excursion runs at the museum. Carved wood trim, brass fittings, sliding end doors, storable windows in roof pockets, and a three-abreast configuration constitute its ornate interior features.

The ,539 New Jersey Transit PCC Car Number 6, first ordered in 1945 as part of a 40-strong fleet by the Twin City Rapid Transit Company from the St. Louis Car Company, connected Minneapolis with St. Paul two years later, operating on the Interurban Line, for which it was ideally suited with its northern winter-combative galvanized steel body; significant, nine-foot width for interior volume; two-person conductor booths; and electric horns.

Its "PCC" designation, an abbreviation of "President's Conference Committee," stems from the fact that it was the result of the new trolley standards it created in an attempt to increase street car ridership, which had increasingly migrated to individual automobiles.

Car Number 6, one of 30 acquired by Newark, New Jersey-based Public Service Coordinated Transport in 1953 after the Minnesota system had substituted its own trolleys with diesel buses, plied the short, 4.5-mile, municipally-owned Newark City Subway. But the late-1990s signaled its own end when the trolley line was converted to a light rail one.

Having been the second of the last to operate over the network before it was withdrawn from service, it hibernated in storage for a decade until it was purchased by the Rockhill Trolley Museum in 2011.

Philadelphia Transportation Company Car Number 2743 is another product of the President's Conference Committee. Sporting a line of small, "standee windows" above the standard-sized ones, it offered increased acceleration and decreased interior noise levels over the older cars it replaced, operating with the Philadelphia Transportation Company from 1947 to 1993, a year after which it was acquired by the museum--although its five-foot, 2 1/4-inch wheel trucks had to be replaced with four-foot, 8 ½-inch ones before it could run on its tracks.

Capable of sustaining 70-mph speeds, and sporting contoured, bullet-shaped ends, Philadelphia and Western Railroad Car Number 205 is the "bullet car" in the collection. Manufactured by Brill in 1931, the aerodynamic-appearing vehicle employed lightweight aluminum, reducing structure weight, fostering increased speed, and requiring reduced power to propel, siphoning its electricity to run from a third rail and therefore not sporting the otherwise traditional trolley pole. Secondarily acquired by the Southeastern Pennsylvania Transit Authority, or SEPTA, it provided 59 years of service before nudged into the museum's growing collection.

Its largest car is the "Independence Hall" Liberty liner. Spanning 156 feet in length, the permanently-attached, quad-car interurban, designed by the St. Louis Car Company in 1941, features eight, 125-hp articulated traction motors, and served the Chicago North Shore and Milwaukee Railroad's North Shore Line along with its identical twin, attaining 90-mph speeds on the windy city-Milwaukee sector. Both were designated "Electroliners."

Subsequently bought by the Philadelphia Suburban Transportation Company after the twin city link had been discontinued in 1963, the refurbished interurbans, named "Independence Hall" and "Valley Forge" Liberty Liners, entered service on its relatively short, 14-mile Norristown Line, for whose curves and hills it was less than optimal, although its passenger-popular tavern car sold alcoholic beverages, snacks, and meals during the trip.

Acquired by the Rockhill Trolley Museum after it was offered for sale in 1981, it appears similar, although for larger, then the only rapid transit car in its collection, Philadelphia Subway Number 1009.

Manufactured itself by the J. G. Brill Car Company in 1936, it saw initial deployment on the Delaware River Bridge Commission's Benjamin Franklin Bridge Line, shuttling passengers between Philadelphia and Camden. Its City of Brotherly Love service was retained with the Broad Street Subway, which subsequently purchased it and operated it until 1984, at which time it was replaced by state-of-the-art Japanese cars and donated to the museum.

Track-plying maintenance vehicles also take their place in the collection. Philadelphia and Western Railroad plow Number 10, for instance, a "sheer plow" produced by the Wason Manufacturing Company in 1915, canted snow to either side of the track. Bought from SEPTA in 1988, it is the last snowplow trolley to have been used by any US transit system, although it is employed by the museum for the same track-clearing purposes.

Actual car maintenance and restoration can be viewed on shop and car barn tours, while six departures offer trolley ride opportunities on the 1.5-mile Shade Gap Branch of the East Broad Top Railroad, with which it closely coordinates, to Blacklog Narrows, passing the remains of the original iron furnaces, which are now reduced to skeletal brick walls and coke oven ruins. A single ticket accesses unlimited rides for the day, which take about an hour for the three-mile round-trip. Like the East Broad Top Railroad itself, which the trolleys usually meet upon return, the Rockhill Trolley Museum, open on weekends between June and October, schedules several seasonal trips, including those highlighting trolley equipment, fall spectaculars, and Pumpkin Patch, Polar Bear Express, and Santa runs. Its gift shop features a rail-related photographic collection.
