After the increasingly critical situation in the German locomotive building industry around 1929 the works was closed in November 1929.
Locomotive number 80 030 in the Bochum-Dahlhausen Railway Museum was one of the last built by the Lokomotivbau Hohenzollern and is preserved today in photograph-grey livery.
Hohenzollern supplied a 1,200 horsepower (890 kW) diesel-mechanical locomotive to the Russian State Railways in the 1920s.
Around the same time, Russian State Railways also took delivery of a 1,200 horsepower (890 kW) diesel-electric locomotive, class E el-2, designed in Russia by Professor Lomonosov.
Work on this locomotive was started by Hohenzollern, but for political reasons, it was later transferred to Maschinenfabrik Esslingen.
