The exhibit is a representative of DRG (Deutsche Reichsbahn Gesellschaft) German railways  standardized express steam locomotives of 03 series, manufacture of which between 1930-1937 (in number of 298 copies)  was undertaken apart from the BMAG, also by the following companies: Lokomotiv Borsig-Werke GmbH (Berlin-Hennigsdorf), Friedrich Krupp AG Lokomotivfabrik (Essen) and Henschel & Sohn (Kassel). Locomotives were  assigned to service on the routes where permitted axle load limit on the surface is 18 t. Between 1945-46 the Polish State Railways took over 35 of such machines, which during their service stationed in the following locomotive sheds: Osobowa Poznań, Bydgoszcz Główna, Iława, Toruń and Olsztyn. Pm2 locomotives played an important role in handling express  traffic and were remembered by the traction staff as a very slick construction. The exploitation of  the series was ended in 1978.
