Mecklenburg Friedrich Franz 2-6-0 Locomotives in Germany

Class T4 / BR 91.19 (Locobase 6039)

Data from US Military Railway Service Equipment Data Book -- German Locomotives supplied from the extensive collection of Allen Stanley (March 2004). Additional data and information from Christian Lindecke ([] ..., 15 May 2004).

These little tanks were modeled on the Prussian T9s for the MFFE and used an Adam axle as did the KPEV locomotives. One result of the use of a radial axle is the relatively great distance between the lead truck and the first driver set. Built in small numbers over a number of years by Henschel and Orenstein & Koppel, the class saw a slight increase in driver diameter (50 mm, to 1,200 mm/47 1/4") in the last 20 delivered from 1914 on, which raised maximum speed from 45 km/h (28 mph) to 50 km/h (31 mph). Water tank capacity grew to 1,584 US gal ( 6 cu m) and bunkers later accepted 2 US tons.

All 50 were taken into the DRG with most passing to the East German DRG after World War II. The 6 Deutsche Bundesbahn engines were out of service by 1950, but several DR engines lasted until 1968.
