M-10002

The Union Pacific Railroad's M-10002 was a diesel-electric streamliner train built in 1936 by Pullman-Standard with a prime mover from the Winton engine division of General Motors Corporation and General Electric generator, control equipment 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 convert|1200|hp|abbr=on V16 Winton 201-A diesel engine and the second equipped with a convert|900|hp|abbr=on 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 separable 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 non-streamlined diesel-hauled, heavyweight "Super Chief" on their competing Chicago, Illinois to Los Angeles, California route.

After the introduction of the new EMD E2 locomotives for the "City of Los Angeles" in December 1937, 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 It was withdrawn for the second and final time in May 1943, when the passenger cars were removed.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.
