Diesel locomotives were of interest to the Wehrmacht at a very early stage, as they did not indicate their locations by plumes of smoke. Accordingly, the WR 360 C 14 locomotives were created in the late 1930s as switching locomotives for the army. The war locomotives were used throughout Europe and also in North Africa during the Second World War. The original series was repeatedly further developed, especially with regard to the engine and power transmission. After the war, both the Bundesbahn and the Reichsbahn re-designated diesel locomotives of this type as the V 36 series. More machines were procured from the Bundesbahn in 1950. But it was also used in many European countries, e.g. in Austria by ÖBB as type 2065, in Italy by FS as D 236, in Czechoslovakia by ČSD as T 334.0 and in France by SNCF as Y 50100.

V 36 401
This machine was accepted by the Bundesbahn in Nuremberg in 1950 and put into service in Frankfurt as the V36 401. It changed locations several times during its service life: Frankfurt-Griesheim, Hanau, Wiesbaden, Gießen. In 1968 it was given the code 236 401-6. In 1976 it returned to Frankfurt and was retired there in 1978.
V 36 411
This locomotive was also accepted by the Bundesbahn in Nuremberg in 1950 and put into service in Frankfurt as V36 411. During its time in service it also changed its place of operation: Frankfurt-Griesheim, Hanau, Gießen. In 1968 it was given the code 236 411-5. In 1979 it was taken out of service in Frankfurt and came to our museum in 1982.
