M-10002The Union Pacific Railroad's M-10002 was a diesel-electric streamliner train built in 1936 by Pullman-Standard with an engine from General Motors' Electro-Motive Division and General Electric generator and traction motors. It was the UP's third streamliner, and the last turret-cab streamliner. It had two power cars, the lead, cab-equipped one fitted with a 1,200 hp V16 Winton 201-A diesel engine and the second equipped with a 900 hp V12 Winton 201-A that had been removed from the M-10001 when it was rebuilt. The two power cars were articulated together with a span bolster, giving them an effective wheel arrangement of B-B+B-B, but they were not articulated with the train and therefore formed the Union Pacific's first seperable diesel locomotive. The train was of nine passenger cars plus the two power cars, making it at eleven cars the longest streamliner trainset yet introduced. It entered service as the City of Los Angeles on May 15, 1936, the day after the Santa Fe introduced their first diesel-hauled, heavyweight Super Chief on the same Chicago, Illinois to Los Angeles, California route. At some point after the introduction of the new EMD E1 locomotives for the City of Los Angeles, the train was reassigned to the City of Portland to replace the M-10001. In July 1941, the trainset was placed in storage after it was replaced on that route also. It was reactivated in April 1942 to operate a Portland-Seattle connection. It was withdrawn for the second and final time in May 1943, when the passenger cars were removed. The power cars were eventually sold to Northrup-Hendy for gas turbine train testing in December 1946; they went for scrap in 1947. References
