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 ...
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 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.
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.
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.
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 ...
The LNER added a further five Class T1 locomotives in 1925. These locomotives had three cylinders, following Robinson's design for the 0-8-4T Class 8H of the Great Central Railway. [14] [15] In 1921, the London and South Western Railway (LSWR) built four G16 class two-cylinder tank locomotives to Urie's design, for use in the Feltham ...
The Pennsylvania Railroad K4 was a class of 425 4-6-2 steam locomotives built between 1914 and 1928 for the Pennsylvania Railroad (PRR), where they served as the primary mainline passenger steam locomotives on the entire PRR system until late 1957. Attempts were made to replace the K4s, including the K5 and the T1 duplex locomotive.
