There were 12 of these 3000hp, six-axle units on the WM. The first seven units, 7470-7474 and 7495-7496, were delivered in Speedlettering, with the last five delivered in Circus. The units were equipped with 26L brake gear and brake current limiting on the dynamic brakes. As of the Spring of 1996, all twelve of the ex-WM SD40 units remined in service. All but 4 were working for CSXT. Unit 4618 remained in the Chessie paint scheme, with the WM logo under the cab.
