In order to rationalize shunting operations at larger stations, the Zentralamt of German DB developed a two-axle diesel locomotive with hydrodynamic transmission together with the locomotive manufacturer Gmeinder. The first 300 copies still had a power transmission with chains, the others had a cardan shaft drive. The proven 240 hp RHS 518 from MWM was used as the engine for the series locomotives. The pre-series locomotives later classified as class 331 initially had to be content with a more…

In early 1950s young German Federal Railway (DB) introduced four axle two motor dieselhydraulic V200. The loco is powered by two 12 cylinder 1100 HP diesel made by Daimler-Benz, MAN or mostly a MD650 made by Maybach. For use in passenger service all locos received steam heating equipment by Hagenuk. With its maximum speed of 140 km/h the locos were used for multi purpose. After around 30 years DB discharged the locos. 13 locos went to Italian users, seven were sold to swiss SBB for traction of more…

The Rhetian Railway (RhB) of Switzerland ordered 10 four axle electric locos Ge 4/4 for the meter gauge Stammnetz at SLM in 1947. The 1184 kW locos reach a maximum speed of 80 km/h and are used for passenger and freight service. more…

In the late 1950s the narrow gauge Rhetian Railway (RhB) of Switzerland recommended stronger locos for haevy freight and passenger service. After a pre-series of two six axle locos (#701 and #702) the RhB ordered a series of five more locos (#703 - #707) that show differences in front design. Technical equipment of the locos is the same. The end trucks are interchangeable with those of four axle Ge 4/4 I. The locos develop 2398 HP and reach a maximum speed of 80 km/h. Even after around 50 years more…

Due to the lack of heavy express train steam locomotives of the 01 series, the 03, which was less suitable for these services, had to step in in the 1950s and 1960s. Since the locomotives were still quite new in the 1950s and in good general condition, the DR decided not to reconstruct them. However, after the very new boilers of the 22 decommissioned (reconstructed BR 39, ex. pr. P10) were available from 1969, 52 old building 03s were equipped with these Reko boilers. At this point, the DR's more…

From 1942 the class 52 was derived from the light but powerful class 50 goods train tender locomotive developed from 1937 and mass-produced from 1939. Despite numerous simplifications, the war locomotive with 1640 hp had the same performance as the 50 and also reached 80 km/h when driving forwards. Initially, smoke deflectors were also dispensed with, but after a short time smaller Witte plates were retrofitted compared to the 50. So that the locomotives could withstand the winter in the more…

The Deutsche Reichsbahn-Gesellschaft had the class 03 developed to supplement the heavy express train locomotive 01, which was designed for operation on well-developed main lines. Between 1930 and 1937, 298 examples of the 1980 hp two-cylinder locomotive with a top speed of 130 km/h were built. In front of light and medium-heavy passenger trains, the three-couplers impressed with their good driving characteristics, but in many DB departments in the 1950s the travel times of the express trains more…

In the late 1950s German Deutsche Reichsbahn DR decided to modernize war-design freight locomotive BR 52. Around 200 samples received new boilers. The locos developed 1600 hp and reached a maximum speed of 80 km/h. With its axle load of only 16,3 tons the locos were used for freight and passenger trains even on branch lines.

In 1939 German Deutsche Reichsbahn-Gesellschaft DRG received 1st of more than 3100 samples of 2-10-0 two-cylinder steam loco BR 50. The loco developed 1625 HP and reached a maximum speed of 80 km/h. With its axle load of just 15,2 tons the locos were used even on branch lines with light weight rails. Locos of DB quitted service in 1977, the DR locos were used for ten more years.
