of freight locomotives, and is often referred to as a Dash 8-40CM. Mechanically identical to the Dash 8-40CW, the Dash 8-40CM was constructed only for Canadian railways, with a production total of 84 units. It is distinguished from the Dash 8-40CW by the addition of a full-width "Draper Taper" style cowl body, of which they are the last locomotives built with this feature, and the use of a Canadian-specific nose and windshield configuration. The trucks also differ; all units built ride on Dofasco Hi-Ad trucks identical to locomotives built by Montreal Locomotive Works, Bombardier, and Morrison-Knudsen.

Technical

The Dash 8-40CM is powered by a 7FDL- 16 diesel engine driving a GE GMG187 main

alternator An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature.G ...

. The power generated by the main alternator drives six GE 752AG or 752AH

, each with a gear ratio of 83:20 and connected to wheels which allow the Dash 8-40CM a maximum speed of 70 mph (110 km/h). Depending on customer options, the Dash 8-40CM carries approximately of diesel fuel, of lubricating oil, and of coolant. Like most North American diesel locomotives, the Dash 8-40CM uses normal water for cooling. The Dash 8-40CM has a tractive effort rating of at . Overall dimensions for the Dash 8-40CM are in Length, in height and in width.
