Swiss Federal Railways
1001 & 1002
(later 18451 & 18452)


During 1939 Swiss Federal Railways took delivery of two 1,200hp Bo-Bo diesel-electric locomotives for use on secondary routes.


Built by SLM, with electrical equipment by Brown Boveri Company and powered by a Sulzer 8LDA28 in line power unit, the locomotive weighed only 65 tons with a maximum speed of 68mph (110km/h). A dc traction generator and train heating alternator were carried on the same frame running at 750rpm. They were equipped for multiple unit operation, allowing them to be used on sleeper trains.
