GLS 30 + 2 WAGONY-KOLEBY POLSKI WĄSKOTOROWY POCIĄG PRZEMYSŁOWY Z 1957 ROKU

GLs30 is a series of narrow-gauge diesel industrial locomotives, which were produced in the years 1961-1964 at the ZRMB plant in Gliwice. The service weight of a single locomotive was 4 tons, and its length with buffers - 2.91 m. The locomotive was constructed using the B axis system. In total, about 160 were produced. The GLs30 locomotive was created due to the demand of the Polish heavy industry for narrow-gauge locomotives, as well as the lack of spare parts for structures of this type manufactured abroad, and used in Poland after 1945. When producing GLs30, it was decided to rely only on Polish subassemblies and components. The locomotive was powered by a single 30 HP S-322 engine, it also had a mechanical transmission and a small fuel tank. Due to the commencement of production of narrow-gauge locomotives at the plants in Fablok and in Poznań, the GLs30 locomotive ceased to be ordered. At present, it is used to a minimal extent.
