DIESEL PASSENGER LOCOMOTIVE Designed and Built For THE GREAT NORTHERN RAILWAY COMPANY By Electro-Motive Division * General Motors * La Grange, Illinois This diesel passenger locomotive consists of two lead units. Each unit is equipped with two General Motors 12 cylinder, V-type, 2-cycle Diesel engines having a bore of 8 1/2 inches, stroke 10 inches and a unit fuel injection system. These engines are rated at 1000 HP each at 800 RPM, providing a total of 4000 HP for the locomotives. Each engine is directly coupled to a DC generator. Current from these generators is fed through control apparatus to four traction motors - two to each truck - and geared directly to the driving axles. Two six-wheel trucks are used in each of these units for smoother operation in the upper high-speed range, middle wheels being designed to aid in weight distribution only. SPECIFICATIONS: Dimensions: Overall length over couplers: 142'-2 1/2" Maximum width over grab irons: 10'-6 7/8" Width over body posts: 9'-10" Height overall above rails: 14'-10" Wheel diameter: 36" Rigid wheel base of trucks: 14'-1" Roller bearing journals: 6 1/2"-12" Truck swing designed for 21 degree curve or 274-foot radius Distance between truck centers (each unit): 43'-0" Supplies: Fuel oil: 2400 gals. Sand: 32 cu. ft. Lubricating oil: 560 gals. Engine cooling water: 600 gals. Boiler water: 2400 gals. Weights: Total weight fully loaded: 634,240 lbs. Weight with one half of variable supplies: 613,500 lbs. Maximum tractive effort at rim of driving wheels at 25% adhesion: 103,380 lbs. The Great Northern Railway was first of the northern transcontinentals to utilize 5400 HP Diesel freight locomotives, built by Electro-Motive Division of General Motors. A large fleet of these and 6000 HP diesels transport freight faster over mountain territory. |
