HistoryEdit

The first two T1's (6110 and 6111) were built by the Baldwin Locomotive Works in 1942; unlike later T1 designs (which were built at the PRR's own workshops in Altoona, they were slightly different. Their number keystone was on the bottom of the front and the tender was different. From 1945-1946, fifty more T1's (5500-5549) were built. They were to be the next generation of steam passenger service. But like the Erie Triplex before and the S1 No. 6100 which was soon to perish, due to the troublesome nature with the drive gear, the T1 was susceptible to wheelslip, But they could reach the steam locomotive speed record easily. When the PRR purchased diesel engines, they were downgraded to mail and secondary express passenger service, they were retired in 1952 and scrapped in 1956.

PRR T1 TrustEdit

In 2014, a non profit group called The Pennsylvania T1 Steam Locomotive Trust was formed by some preservation experts to build a new T1 and number it #5550. The year 2015 was a major turning point for the company as they reached for their goal of $20,000. The new T1 is expected to be completed in 2030.

TriviaEdit

  • The South Australian Railways 520 Class has a similar design to these shark-nosed giants; however, those engines are 4-8-4 Northern type engines.
  • The original T1's had a rounded bottom front with the number printed on it and the tender had the legend Pennsylvania painted in yellow and the PRR Keystone printed in a circle next to it. In the first few 5500 class engines, the tender was repainted to have the keystone painted above the lettering; on the last few engines built, the rounded front was flatter, The Keystone was made of brass and it was moved to the "nose" of the engine.
