ATSF #2912 - The 2912 was built by Baldwin in 1944.  Wartime restrictions of materials made unavailable certain steel alloys, resulting in the 2900 series being the heaviest of the 4-8-4 "Northern" locomotives built.  The 2912 with tender weighs just under a million pounds.  The 2900's were also among the fastest, carrying 300 lbs. boiler pressure and 80" diameter drivers.  They usually served in passenger service between LaJunta, Colorado and Los Angeles, California.  Northerns, however, were "general purpose" engines and could be seen on both passenger and freight consists.
