They were no longer in service there, because the Reich railways purchased them immediately after their delivery.
Locomotive 102 was still occasionally working in 1918 (as a so-called Auswaschlokomotive) in the Mühlhausen area.
The locomotives had an inside frame and the boiler had three shells, the rear one being crowned by the steam dome.
The locomotive had an outside, twin-cylinder wet steam engine and an inside Allan valve gear.
The locomotives were later fitted with a Westinghouse compressed-air brake, a steam heating system, washout equipment, sand distributor and adjustable blastpipe.
