M-10002

The Union Pacific Railroad's M-10002 was a diesel-electric streamliner train built in 1936 by Pullman-Standard, with prime movers from the Winton Engine division of General Motors Corporation and General Electric generator, control equipment and traction motors.

However, the demands of Chicago-to-west-coast service led UP to expand the consists from six to nine cars and seek more power for the larger trainsets.

M-10002 entered service as the City of Los Angeles on May 15, 1936, the day after the Santa Fe Railroad introduced their first non-streamlined diesel-hauled, heavyweight Super Chief on their competing Chicago, Illinois to Los Angeles, California route.

The train was reactivated in April 1942 to operate on a Portland-Seattle connection, then withdrawn for the third and final time in May 1943 and the passenger cars removed.

[1] M-10002 remained the longest in Chicago-to-west-coast service among the original fleet of Union Pacific streamliners, just under five years.
