Chesapeake & Ohio Tests the PRR T1 - Chesapeake and Ohio Historical Magazine, May 2005 by Stephenson, David R - The C&O test report contains information that is not widely known, and some of it contradicts generally accepted beliefs about the T1. Photos of PRR 4-4-4-4 locomotives; An N Scale PRR T1 4-4-4-4 scratch building project; A group that ...
The PRR also desired to apply the duplex principle to freight haulage, and the Q1 was the first experiment in that direction. It was a 4-6-4-4 fast freight locomotive, delivered in May 1942. Like the B&O's George H. Emerson it had the second pair of cylinders facing backwards, and all were fitted with standard Walschaerts valve gear.
Nine T-1's (Nos. 2107, 2111-2115, 2119, and 2128) were leased to the Pennsylvania Railroad (PRR), while others ran upstate in Pennsylvania on the RDG, until early 1957. Some T-1s were also loaned as steam generators to Steel mills. Upon returning to the RDG the following year, the PRR-leased locomotives, with the exception of No. 2128, were ...
The whole S1-T1 venture resulted in losses for PRR and investment in a dead-end development effort for Baldwin at a critical time for both companies. In the early 1940s Baldwin embarked upon its efforts to develop steam turbine power, producing the S2 direct-drive turbine locomotive in 1944.
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.
Besides the R1, the PRR did not build or order any other 4-8-4 locomotives, however the T1 duplex was essentially a 4-8-4 with two sets of driving wheels as a 4-4-4-4. In many respects the design resembled the earlier, lighter P5, but with an extra driving axle and lower axle loads.
Hours after the St. Petersburg City Council approved spending $23.7 million to repair Tropicana Field after it was damaged during Hurricane Milton, the council reversed its decision in a second vote.
PRR FF1 experimental locomotive PRR GG1 #4890 at the National Railroad Museum in Green Bay, Wisconsin. When work on the Hudson River tunnels and New York's Penn Station was in progress, the type of electric locomotives to be used was an important consideration. At that time only a few electric locomotives existed.
