The locomotives of the series Ty37 of the Polish state railway PKP are freight locomotives with the wheel arrangement 1'E.
The constructive successor of the PKP series Ty23 was the Ty37, which, with similar proportions, was able to offer higher performance, especially due to the increased boiler pressure. The locomotives were developed and built at Cegielski in Poznan. A larger number was not built, but the Ty37 for the DR became the model for a two-cylinder 1'E in the axle load class between 15 t and 20 t, which was then realized as the DR series 42 . For the PKP, 27 units were initially delivered and put into service. After the Polish campaign , 18 Ty37s were initially taken over by the DR. Due to the good performance and experience with these locomotives, it was decided to reorder ten more. These were delivered in 1940 by DWM Posen, as Cegielski had been called since November 1, 1939. Initially, the first five subsequently delivered locomotives were numbered as 58 2718p - 2722p , but later classified with the rest of the number series 58.29 . Of the eight locomotives of this series registered by the NKPS in September 1939, only the former Ty37-10 came into German possession during the German-Soviet War and was classified as 58 2929 as the last locomotive. After the Second World War, eight locomotives remained in the western zone and were added to the DB . 13 came back directly to the PKP and eight were registered in the Soviet Zone . The latter locomotives had to be returned to the PKP in 1949, which increased the number of locomotives to 21 Ty37s.
In Poland the last Ty37s were retired in 1977. The Ty37 of the DB were already scrapped in 1951 due to an instruction from the occupiers because of the steel shortage during the Korean War. Ty37-17 (ex 58 2909, ex Ty37-16) has been preserved as a museum locomotive in Jaworzyna Śląska .
