History:
Designed for fastest passenger service the T1 locomotive was everything: beautiful to behold, unusual, powerful, & fast. The Pennsylvania Railroad's 52 T1 class duplex-drive 4-4-4-4 steam locomotives, introduced in 1942 (2 prototypes) and 1946 (50 production), were their last-built steam locomotives and their most controversial. They were ambitious, technologically sophisticated, powerful, fast, and uniquely streamlined by Raymond Loewy. However, they were also prone to violent wheelslip both when starting and at speed, complicated to maintain, and expensive to run. In 1948, the PRR vowed to place diesel locomotives on all express passenger trains, leaving unanswered whether the T1's flaws were solvable. However, a Spring, 2008 article in the Pennsylvania Railroad Technical and Historical Society Magazine revealed that the wheel-slip problems were caused by the failure to properly train engineers transitioning to the T1, resulting in excessive throttle applications, which in turn caused the wheel-slips on this very powerful locomotive.

There were two experimental engines, the first, the 6110, and the second the 6111, both were built in 1942 by Baldwin for the war time traffic. The 6111 was equipped with a Franklin booster in its trailing truck; this added 13,500 lbs. of tractive effort, no other T1's had boosters. In April 1944, the 6110 was sent to Altoona test plant for a thorough instrument check after compiling 120,000 miles of road service. The test reports were excellent and elated PRR motive power men placed orders for fifty engines. All of the engines were built during 1945 and 1946. Altoona built locomotives 5500-5524, plus all the tenders, while Baldwin built locomotives 5525-5549. Only very slight modifications appeared in the design. The T1 was the last steam locomotive to be built in the Altoona Juniata Locomotive Shops. Their memory will remain strong for many years to come, and sorry to say none were saved. All of the engines were sent to the scrap yards.
