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. It was delivered on October 2, 1934, and was used for display, test and record-setting runs for the next two months before being returned to Pullman-Standard for an increase in power and capacity, following which it was placed into service as the City of Portland train. It has been nicknamed "The Banana".
