Konstal N was a tram model based on the German Kriegsstraßenbahnwagen concept, manufactured between 1948 and 1956 by the companies Konstal in Chorzów, Gdańsk Shipyard no. 3 and Sanok Railcar Factory "Sanowag". The narrow-gauge version (Konstal 2N) was built from 1950 to 1956. Trailers (tram units with no engine) were marked ND or 2ND. The N was the first tram manufactured in Poland after the Second World War.^[1]

The N was a bidirectional motor tramcar, equipped with four sliding doors.

In post-war Poland, many cities struggled with significant shortages of rolling stock, and therefore it was necessary to develop a tram with simple construction and easy assembly. It was decided to copy the construction of the German tram Kriegsstraßenbahnwagen (KSW),^[2] developed during the Second World War to satisfy the demand of local tram transport companies. Due to the lack of motors, initially the ND trailers for Upper Silesia were built.^[1]

The successor of Konstal N was Konstal 4N.^[3]

The N standard-gauge trams were supplied to: Gdańsk, Gorzów Wielkopolski, Sopot, the Upper silesian conurbation, Kraków, Poznań, Szczecin, Warsaw, and Wrocław, while narrow-gauge versions were used, among others, in Bielsko-Biała, Bydgoszcz, Grudziądz, Elbląg, Inowrocław, Jelenia Góra, Legnica, Łódź, Olsztyn, Słupsk, Toruń and Wałbrzych.

To this day, two units are operated in Bytom, where they are used on a single-track tram line no. 38 during weekends, replacing one regular tram. These are trams no. 954 from 1949, and no. 1118 from 1951.^[4]
