I'm not surprised at these revelations. I've read that in the late 1930s, PRR top management intended a major speedup of both passenger and freight trains on its main lines. The T1 and Q2 duplex locomotives were part of this program, since the intent of the duplex design was to minimize the constantly shifting weight of the siderods, which would allow higher speeds. Electrfication to Pittsburgh was also part of this plan. However, World War II interrupted the program, while postwar dieselization diverted the capital it would have needed.
There can be no question that the T1s could have pulled passenger trains at 100-120 mph in normal service, as could have the GG1s. However, the overall PRR speedup required track and alignment upgrades that never took place, and the PRR never made money after World War II. This was all nothing but a might-have-been, and the T1 was just an artifact of that circumstance. No matter, railfans have created something of a fantasy around the PRR, and the T1 is an important part of it.
Enter the T1 Trust. Chrome A1 mode does a good job of summarizing the main points the T1 Trust itself doesn't quite make on its own website:
The T1 Trust, formally known as the Pennsylvania Railroad T1 Steam Locomotive Trust, is a non-profit organization building a brand-new, fully functional Pennsylvania Railroad (PRR) T1 class steam locomotive from scratch. This new locomotive, numbered 5550, will be the 53rd member of the class, as all 52 original T1s were scrapped decades ago.All well and good, but to break the steam world speed record, you're going to need to have track that allows speeds over about 130 mph. In North America, there are only two possibilities, the DOT test track in Pueblo, CO, and the Amtrak Northeast Corridor in a few stretches. Whether the DOT would allow a steam loco on its test track is an open question -- steam locomotive siderods put a shifting load on the rail that could damage the track. The same applies to Amtrak, with the additional problem that to avoid interruption of normal schedules, a test could only be done in the very early morning, making daylight photography impossible.Project Overview
- Mission: The Trust aims to reignite the golden age of steam by building a powerful mainline excursion engine that will also attempt to achieve the world speed record for a steam locomotive.
- Design: The PRR T1 was an advanced, streamlined 4-4-4-4 steam locomotive known for its speed, power, and art-deco design. The new locomotive 5550 will be a "continuation" of the class, incorporating modern welding techniques and other subtle engineering improvements while maintaining the original spirit and appearance.
But there's an additional problem that even to run rthe T1 at 70 mph speeds on a Class 1 mainline, the Class 1 railroad has to think this is a good idea. The UP runs its own steam locos, because they put the UP name in front of the public. Other railroads have proven less and less likely to allow steam excursions. A PRR that would gain publicity by running a T1 is long dead; Norfolk Southern wouldn't see the point. Steam excursions attract large crowds of spectators along the tracks, with the potential for irresponsible behavior, significantly increasing the potential for accidents and liability issues.
In addition, in recent decades, the North American rail network is essentially full. Excursion trains can disrupt schedules and require significant extra manpower to manage the public and ensure smooth operations, which the railroads are often unwilling to provide. The amounts needed for indemnification and insurance coverage are probably beyond even the T1 Trust. But beyond that, most excursion steam locomotives run with a diesel helper no matter what, to be sure the train can be pulled off the main line if the steam loco fails. But no diesel helper can run at 100-140 mph in any case.
So as a practicasl matter, the T1 will normally operate on museum or preservation railroads where the speed limit is much lower and the track might not even accommodate the T1's weight. But let's grant the best possible case: let's say the DOT allows the faux T! on its test track, and it smashes the previous official world speed record for a steam locomotive of 126 mph -- hey, grant that it'll do over 140. This will never be anything but an asterisk in the record book, taking place maybe a century after the last record, which was set during the actual age of steam.
The PRR of railfan and modeler fantasy never actually existed, and I say this as someone whose lifetime train riding mileage was overwhelmingly on the old, actual PRR -- I commuted to school several times a year on the whole length of the norheast corridor. It was never much fun. The T1 Trust is a chimera.
