The GE C40-8W is a 6-axle diesel-electric locomotive built by GE Transportation Systems from 1989 to 1994. Often referred to as the Dash light series, it is part of the GE Dash 8 Series of freight locomotives. This locomotive model is distinguished from the predecessor Dash 8-40C by the addition of a newer "wide" or "safety" cab. A cowl-bodied version of this locomotive, built only for the Canadian market, was the GE Dash 8-40CM.
