History
In the early 1930s, D.I. Kondratiev and a group of Leningrad specialists visited America to learn about local developments. A new model of the Leningrad tram was derived from this research trip based on the Peter Witt design. The design was modified in accordance with Soviet domestic requirements; in particular, the width of the wagon was reduced. The first tram of this design was produced by PTMF. It was originally named MA, and its unpowered trailer was named PA. The model quickly earned the nickname "American". Later for political reasons, the wagon names were changed to LM-33 and LP-33, respectively.LM-33 and LP-33 were built between 1933 and 1939.
