	PRR locomotive classification - Biocrawler (Site not responding. Last check: 2007-10-11)
		Early on, steam locomotives were given single letter classes, but given that only 26 of these were available, the scheme quickly ran out of available classifications.
		The 4-4-2 "Atlantic" type was assigned class E. The PRR was an enthusiastic user of the Atlantic type in flatter country, and built some of the most advanced Atlantics used in the United States.
		The PRR never built any steam locomotives of the 4-8-4 "Northern" type, although the T1 duplexes were effectively a "Northern" with the driving wheels split into two groups.

	PRR S1 - Trains (Site not responding. Last check: 2007-10-11)
		The S1 was a duplex locomotive: it had two pairs of cylinders, each driving two pairs of driving wheels, but its driven wheelbase was rigid, unlike similar-looking articulated locomotive designs.
		The six-wheel leading and trailing trucks were added as the locomotive's design became too heavy for four-wheel units, but the locomotive was still overweight by a significant margin.
		PRR instead turned its attention to the T1 class of 4-4-4-4 duplex locomotives, but they also met with limited success.

		This was used for all of the PRR's steam locomotives, and — with the exception of the final type bought (the E44) — all electric locomotives also used this scheme.
		The PRR never built any steam locomotives of the 4-8-4 "Northern" type, although the T1 duplexes were effectively a "Northern" with the driving wheels split into two groups.
		The PRR classified articulated locomotives and joined locomotive units by using multiples of the previous classifications.

	Locomotives on the Madison Hill (Site not responding. Last check: 2007-10-11)
		Like other locomotives used on the Hill until 1926, it was a saddle tank locomotive, whose water and fuel were carried in tanks and bunkers on the locomotive itself, without the use of a separate tender.
		The two gears on the locomotive were in a frame that could be raised and lowered by a fifth cylinder to disengage the pinion from the rack when the locomotive was not operating on the incline plane.
		The locomotive frame and its wood box behind the cab were shortened, and it gained a saddle tank and lost a rear set of drivers.

	2-8-0 - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-10-11)
		Of all the locomotive types that were created and experimented with in the early part of the 19th century, the 2-8-0 was a relative latecomer.
		The first locomotive of this wheel arrangement was likely built by the Pennsylvania Railroad (PRR), but like the first 2-6-0s, this first 2-8-0 had a leading axle that was rigidly attached to the locomotive's frame.
		The locomotive Consolidation, built in 1865 is widely considered the first true 2-8-0 built in the United States.

		classification is used to describe the wheel arrangement of conventional steam locomotives.
		The system used to describe electric locomotives uses a series of numbers and letters separated by hyphens to indicate the number of powered and non-powered axles.
		On the PRR, steam locomotives were classified using single letters starting with "A" for the 0-4-0 and moving down the alphabet as the number of wheels increased.

	PRR Steam Roster Pt1 - NE Rails
		The PRR's original locomotive classification system was in force between 1867 and 1895.
		By the early 1890s nearly every letter of the alphabet had been assigned and locomotives with quite different specifications were being lumped together in a single class.
		The letter A was assigned to locomotives of the 0-4-0 wheel arrangement, with the oldest major variation of this type being identified as Class A1 and the next as Class A2.

	PRR S1 - Wikipedia, the free encyclopedia
		The Pennsylvania Railroad's class S1 comprised a single steam locomotive of 6-4-4-6 wheel arrangement in the Whyte notation, the only locomotive of such arrangement ever constructed.
		Its high speed capability was such that some have claimed the S1 may have even exceeded the 126 mph record steam locomotive speed set in 1938 by the LNER locomotive Mallard.

		PRRs are considered a part of the Innate Immune system (as opposed to the Adaptive Immune System); Innate Immunity reacts faster to infections and is comprised of phagocytic cells, the complement system and a number of soluble inflammatory mediators such as antibacterial peptides and cytokines (see Table 1.3).
		PRRs are located on APCs, T cells (20) and some epithelium (21) and recognize highly conserved sequences within bacterial structures or PAMPs (pathogen-associated molecular patterns).
		According to a recent systematic classification (40), chemokines are divided into four distinct subfamilies based on the configuration of their aminoterminal cysteine residues (Table 1.4).

		Other cut-backs made were closings of some shops, removal of some excess track, many locomotives (especially poorly-maintained locomotives) were put out of service (and stored long enough to cause further damage to the units), a more less expensive paint scheme was used on locomotives (orange/red and fl with white lettering).
		They also were being put in a tight spot due to the proposed Penn Central merger of the NYC and PRR, because this would have left the NH surrounded by a large railroad, in a hopeless competitive position.
		PRR and NYC were denied that request and were basically forced to merge with the NH by order of the ICC.

		The PRR was the largest railroad by traffic and revenue in the US throughout its 20th century existence and for a long while was the largest publicly traded corporation in the world.
		The PRR used track pans extensively to pick up water on the move, so the tenders of their locomotives had a comparatively large proportion of coal (which could not be taken on board while running) compared to water capacity.
		The PRR was wary of gadgets and its locomotives were not generally festooned with devices; the PRR also favored a neat mounting of such devices when necessary, leaving the lines of the locomotive comparatively clean.

		However, unlike modern hump operations, the Altoona classification was by gravity and cars were slowed manually by a brakeman who rode the cars down the incline to their designated track.

		However, westbound train classification in the 1960’s was never the operational parallel of the eastbound yard.
