The ASME Plaque will read: HISTORIC MECHANICAL ENGINEERING LANDMARK GREAT NORTHERN RY 2313 (MONTANA WESTERN 31) GAS-ELECTRIC RAIL MOTORCAR 1925 GREAT NORTHERN 2313, LATER MONTANA WESTERN 31, IS THE OLDEST SURVIVING ELECTRO-MOTIVE CO (EMC) GAS-ELECTRIC RAIL MOTORCAR. THIS 32 TON CAR RETAINS BOTH THE ORIGINAL WINTON ENGINE TYPE AND GENERAL ELECTRIC TRACTION MOTOR TYPES. IT CONTAINS BAGGAGE AND PASSENGER SECTIONS, AND REDUCED OPERATING COSTS BY FIFTY PERCENT OVER THE STEAM-LOCOMOTIVE TRAINS IT REPLACED. THE EARLY EMC CARS MADE THE FIRST MAJOR USE OF HERMANN LEMP’S CONTROL SYSTEM, TODAY USED ON DIESEL-ELECTRIC LOCOMOTIVES WITH DIRECT CURRENT TRACTION MOTORS.
