Soviet Railways series КЧ-4 (KCh-4)
Soviet Union 1949 424 produced
After the Second World War, the Soviet Union needed a large number of narrow-gauge steam locomotives for use on forest and industrial railways with a gauge of 750 mm. As reparations, a total of 424 locomotives of the КЧ-4 (KCh-4) series were built in Czechoslovakia by Škoda. Like the similar models from East Germany, Poland, Hungary and Finland, it was a 0-8-0 with a separate tender. Originally their plans had been drawn under the type designation П24 (P24) by Kolomna. Some have been preserved and No. 332 has already been operated in Estonia, Latvia and Lithuania.
