Built in the late 1980's by GE, the DASH 8-40BW diesel locomotives were identified by their dynamic brake gear located along the roof line between the cab and engine compartment, with ventilation provided by large roof-top grilles. At this time, U.S. railroads began adopting the comfort car wide-nose designs, the "W" in Dash 8-40BW reflects this cab style. These four-axle, high horsepower engines are still in service today in North America.
