==History== KTM/KTP1 development began after World War II. The production of experimental KTM/KTP-1 trams began in December 1947 in a tram manufacturing plant in Ust' Katavsk City. In the next year, the plant started serial production of the trams. Production lasted until 1961, when the plant switched to the production more modern KTM/KTP-2 trams.
