context_page_description: The SM15 is a Polish diesel shunter used by PKP and industry — where it carried the designation Ls750H. It is based on the Soviet ТГМ3 locomotive.
context_section_description: Between the years 1963–1966, a total of 56 locomotives had been produced — 27 of which were used by PKP. Of the latter 27, the first two units (SM15-01 and SM15-02) were built at the Людиновский тепловозостроительный завод (en: Lyudinovo Diesel Locomotive Factory) and exported to Poland. Production then resumed at the Fablok factory in Chrzanów where the remaining 25 units, earmarked for PKP, were built.
  The newly built SM15s were assigned to the depot in Kraków Płaszów, before being withdrawn from service in the late 1960s and early 1970s, when the SM42 series replaced them. Despite their relatively short operational history, the engineers who drove the locomotives remember them as being very powerful machines.
