Before Pennsylvania Railroad commissioned Baldwin Locomotive Works for the T1 in 1940, it had already begun developing duplex designs for fast locomotives since 1938, including a rigid-frame 4-2-2-4 and three-cylinder 4-4-4 for lightweight trains and the preliminary design for a 4-4-4-4 for heavy trains; BLW presented these designs to several ...
In 1949, few railroads were interested in new steam locomotives due to steady improvements in diesel-electric locomotives. It is possible that CB&Q 4-8-4 5601 was experimentally equipped with a six-wheel trailing truck to allow use on branch lines with lighter rail, but the experiment was unsuccessful.
Most powerful steam locomotive ever static tested. PRR S1: Pennsylvania Railroad: 6100 Altoona Works: 1939 Steam 6-4-4-6: 487 tonnes (537 short tons) 76,403 pounds-force (340 kN) 7,200 horsepower (5,369 kW) Fast passenger steam locomotive; the magazine Popular Mechanics cites 1941 a speed of 133.4 mph (214.7 km/h) PRR S2: Pennsylvania Railroad ...
Stourbridge Lion was one of these three locomotives built by Rastrick, but Stephenson's shop had completed their locomotive, the Pride of Newcastle, before any of Rastrick's locomotives. The Pride of Newcastle even arrived in America nearly two months before the Stourbridge Lion , but it was the latter that was used for the first railroad trials.
Pennsylvania Railroad 5550 (PRR 5550) is a mainline duplex drive steam locomotive under construction in the United States. With an estimated completion by 2030, the locomotive will become the 53rd example of the Pennsylvania Railroad's T1 steam locomotive class and the only operational locomotive of its type, [7] as well as the largest steam locomotive built in the United States since 1952.
No. 123 was designed by the Caledonian Railway's chief locomotive engineer Dugald Drummond in partnership with Neilson and Company which built the locomotive. The engine was a one-off design intended to represent both the railway and the builder at the International Exhibition of Industry, Science and Art held in Edinburgh rather than to fulfill any specific need for such a locomotive by the ...
The museum operates a 7 + 1 ⁄ 2 in (190.5 mm) gauge miniature railway on which these locomotives pull trains that the public can ride. The museum also has multiple smaller gauge railroad layouts for members usage in 4.75" gauge, 3.5" gauge, elevated 1 gauge, and g-scale.
Nos. 630 and 722 pulled many main line excursion trains for the SOU steam program until they were both loaned to the Tennessee Valley Railroad Museum (TVRM) in 1978 and 1980, respectively to make way for larger steam locomotives such as Canadian Pacific 2839, Texas and Pacific 610 and Chesapeake and Ohio 2716 to pull the longer and heavier ...
