Numbers 501-506 were Lima Built for the US Army in 1942, but they were
not the classic WAR TIME CONSOLIDATIONS with export dimmensions.

Class engines showed up on the railroad during the war. The 550 class
were all built by Baldwin except for the last unit number 562 was
Alco built but looked identical. Locomotives nos. 501 and 502 were
received and placed in service by the Alaska Railroad on May 30, 1942 and
June 4, 1942 respectively.
Shown here is number 502 on the turntable waiting to go to work. You can
