GE Dash 8-40CM


The GE C40-8M is a 6-axle diesel locomotive built by GE Transportation Systems from 1990 to 1994. It is part of the GE Dash 8 Series 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 cowl body and the use of a Canada-specific nose and windshield configuration. The trucks also differ; all units built ride on Dofasco trucks identical to locomotives built by Montreal Locomotive Works, Bombardier, and Morrison-Knudsen.

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 maximum tractive effort of at with the 83:20 gearing. Overall dimensions for the Dash 8-40CM are in Length, in height and in width.
