The vehicles of the series V 36.48 (also V 36 K ) were narrow-gauge diesel locomotives of the Deutsche Reichsbahn . The twin-engine locomotives for 750 mm gauge were supposed to replace the steam locomotives on the Saxon narrow-gauge railways, especially the outdated Saxon IV K.
history
There was a wide range of services for the development of the locomotives, which the planned 100 locomotives were supposed to fulfill. For example, the requirements for the universal locomotive for passenger, freight and shunting services included the conveyance of train weights of up to 250 t horizontally at 30 km / h and 100 t on a 35 ‰ gradient at 10 km / h, the smallest passable arc radius of 50 m. Heating and lighting for passenger coaches and use of components from standard-gauge vehicles. Lokomotivbau Karl Marx Babelsberg began developing the locomotive in 1956.
The prototype locomotives V 36 4801 and V 36 4802 were completed in 1960 and 1961, respectively. Since the wheelset driving mass of 9.2 t was above the limit of 7.5 t required for the series vehicles, the test drives could not be carried out on all routes. First tests were carried out in the Wilsdruffer network . The traction achieved met expectations. However, since the wheel set mass was too high, it was impossible to use it on all Saxon routes. The two locomotives also revealed many “teething troubles”. The soundproofing was inadequate, there was a high level of noise in the driver's cab and outside the locomotives, and the accessibility of the units was also poor.
After the trials were completed in autumn 1962, the locomotives were shut down. The reusable components and units have been removed. The locomotives were in Bertsdorf until they were finally scrapped .
