The Class 44 (German: Baureihe 44 or BR 44) was a ten-coupled, heavy goods train steam locomotive built for the Deutsche Reichsbahn as a standard steam engine class (Einheitsdampflokomotive). Its sub-class was G 56.20 and it had triple cylinders. It was intended for hauling goods trains of up to 1,200 tonnes (1,200 long tons; 1,300 short tons) on the routes through Germany's hilly regions (Mittelgebirge) and up to 600 tonnes (590 long tons; 660 short tons) on steep inclines.
The first 10 examples were built in 1926. These engines had a somewhat higher steam consumption than the first ten units of the DRG Class 43 procured in parallel for comparison purposes, and which were equipped with two cylinders. Not until 1937 were further 44s procured, because by then the rising demands of rail transportation could be better met with a triple-cylinder configuration.
From 1926 to 1949, a total of 1,989 locomotives were manufactured. During the Second World War an austerity variant was built with simplified construction and delivery, known as the Class 44ÜK (one of the so-called Übergangskriegslokomotive). This primarily used home-produced materials; components were simplified, both in manufacturing methods and design, or left out completely. The most striking features of the ÜK locomotives were the omission of the smoke deflectors (that from 44 013 was standard) and also the forward side windows of the driver's cab.
After the war, Class 44 locomotives remained with the following railway administrations:
The Austrian Federal Railways (ÖBB) gave 9 engines back to the Deutsche Bundesbahn (DB) in 1952. The DB transferred at least 291 engines to the French railways SNCF as reparations. These were predominantly locomotives that had been built in France. The SNCF sold on 48 engines in 1955 to the Turkish State Railway (TCDD).
