Deutsche Reichsbahn 0-10-0T- Locomotives in Germany


Class Details by Steve Llanso of Sweat House Media

Class Aquarius (Locobase 5853)

Data from [] (24 January 2004) for data on this military light railway locomotive (link later revised to [], last accessed 18 July 2022). Henschel works numb ers were 26462-26466 in 1943/

[] (24 October 2004) explained that Borsig built the prototype in 1939 (Locobase 21159) for the Heeresfeldbahn, but dropped locomotive manufacture in favor of other war production. Henschel supplied five more in 1944 to the Borsig plans.

This is a tank engine with tender; the locomotive carries a small supply of coal and water and trails a two-axle tender as well. So perhaps the Whyte designation could be 0-10-0T+0-4-0

Together engine and tender weighed 40.7 metric tons and could negotiate curves as tight as 30 m (98 ft) in radius. Also note how lightly it rode the rails as it spread its weight over five axles. Its ability to negotiate curves was enhanced by a fixed wheelbase of only 2.7 m (6 ft).


Class Aquarius/60 cm (Locobase 21159)

Data from "Technische Daten und Lebenslauf" at [], last accessed 19 November 2023. Works number was 14806 in 1939.

The website celebrates one of the class in particular, Borsig works number 14806, which served in the German military, then for many years in industrial work, then on several museum railways.

[] (24 October 2004) explains that Borsig built the prototype in 1939, but dropped locomotive manufacture in favor of other war production. Henschel supplied five more in 1944 to the Borsig plans, but enlarged to run on the 75 cm gauge; see Locobase 5853.
