SNCF Class BB 66400

The SNCF Class BB 66400 is a class of centre cab mixed traffic diesel locomotives, a development of the BB 66000 with three phase electric transmission. The 106 locomotives were built for SNCF by a consortium of CAFL, CEM, Alsthom, Fives-Lille and SACM between 1968 and 1971. They are 14.972 metres long and weigh 64 tonnes. The prime mover is an MGO V16BSHR diesel engine developing 1,030 kilowatts, and the maximum speed is 120 kilometres per hour. As built they had no train heating, but they were later fitted with electric train heating and equipped for push-pull working to operate local passenger trains. From 2004 some 75 members of the class were rebuilt with new MTU 12V 4000 R41 engines and reclassified as the BB 69400.
