Hungarian State Railways and Košice–Bohumín Railway XII
Hungarian State Railways class 377, Czechoslovak State Railways class 310.4, and Yugoslav Railway class 152
Austria-Hungary 1885 562 produced
The XII was a small tank locomotive for service on secondary lines, which was produced in large numbers by almost every factory in Austria-Hungary. However, it was only used outside the Austrian part of the empire, since the MÁV had received 549 locomotives and the KsOd 13. It only got its striking appearance later through the installation of a long smokebox that protruded over the buffer beam. After the First World War, the majority was located in Hungary, Czechoslovakia and Yugoslavia. The state railways usually retired the locomotives in the fifties, but in industry they could last into the seventies.
