French manufacturers built almost 700 BR44ük for the Germans during WW2. The BR44ük is the transitional war time design of the BR44: the design was simplified but provisions were made to allow the engines to be restored to their original type after the war. In the BR44ük, the smoke screens, the cab window, the running plate front end, the smoke box door central lock are removed. The German specifications were scrupulously followed but owing to war restrictions, some parts had been replaced by their French equivalent (buffer stock, compressor, injectors, …). Consequently, one engine may be slightly different from the next.

226 engines BR44ük still under construction in 1944 were taken over by the French railway (SNCF) when delivered and incorporated as 150X in SNCF rosters. They were very successfully used for the heavy haul of coal and iron in northern France. Most of the 150X were coupled to a 2'2'T34 tender (SNCF 34X).

In 1954, SNCF sold 48 engines made redundant by 25 KV electrification to TCDD. These 150X were barely 10 years old and in perfect condition. The 48 engines were picked for their original Knorr compressor and Knorr feed water heating already familiar to shop crews in Turkey. All the engines were fully overhauled by SNCF prior to delivery. Overland shipment occurred between 30 April and 25 July 1955. TCDD fitted them with a snowplough and a third light on the smoke box door. Later on, TCDD made other modification to the engines such as the restoration of the smoke box door central lock and the fitting of safety valves on the cylinders.

TCDD kept the 56700's in service until the late 70's (1977?). They were used on all kind of duties from long haul passenger to local freight. Most of them were based at and around Adana shed and were frequently seen (and photographed) working up the Taurus bank to Ulukisla. A batch were used at Bilecik for banking duties up the Karakoy ramp. The cover of the April 1970 issue of Trains magazine has five of these locos together with a 5700 congregating around the Bilecik turntable awaiting their next call to duty.

Engine numbering

The following table give the translation between SNCF numbers and TCDD numbers. On delivery, in 1945, SNCF numbered these loco by using the DRG number prefix by the SNCF class code 150X. In March 1950, SNCF completely renumbered these locos, sequentially starting from 150X1. TCDD numbered the locos more or less in their order of arrival in Turkey. They were given an initial service at Haydarpaşa (H.) or Eskişehir (E.)
