Swiss Federal Railways
1001 & 1002
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.
They were later renumbered 18451 & 18452 (Class BM 4/4 II), up to 1976 they had covered 770,000 & 910,000 miles respectively. 18451 is preserved.
One of the 6LV26 engined 200hp railcars from 1914 survived into preservation and is seen here in 2003 at a museum in Lucerne. (From a photograph by T B Kohler)
