First built for Union Pacific in the late 1980's by General Electric, the DASH 8-40C diesel locomotives were identified by an enlarged exhaust stack and the mounting of the dynamic brake grids in a square-like unit behind the cab, which housed an enlarged equipment blower fan. These six-axle, 4,000 hp engines are still in service today in North America.
