what is it?
The Union Pacific Railroad's M-10001 was a diesel-electric streamlined train built in 1934 by Pullman-Standard with a power system developed by General Motors Electro-Motive Corporation using a Winton 201A Diesel engine and General Electric generator, control equipment and traction motors. It was the UP's second streamliner after the M-10000, their first equipped with a diesel engine and was a longer train (six cars) than its three-car predecessor. All cars were articulated—trucks were shared between each car.
