LM-57 ( Russian ЛМ-57 ) is the name of a tram vehicle built by the Wagonoremontny Sawod in Leningrad (WARS, today Peterburgski Tramwajno-Mechanitscheski Sawod, Saint Petersburg , Russia ) . The abbreviation LM means L eningradski M otorny ( Russian Ленинградский Моторный , German Leningrad railcars), the number 57 corresponds to the development of 1957. All of the cars of this type were way vehicles and perverse only on lines with turning loops or triangles to the path statements.

construction

From a technical point of view, the LM-57 was a transitional design from old cars to the more modern PCC- like trams. It has two identical frameless bogies with only a single suspension stage as authentic PCC cars, but unlike them, it was equipped with the old direct control instead of an accelerator. This constructive solution made driving in traction in the standard version impossible. The LM-57 did not have a sidecar variant either, so it could only be operated as a solo multiple unit.

commitment

WARS manufactured the LM-57 prototype in 1957, after the production and reworking of the small pilot series in 1958–1960, series production of the vehicle began in 1961. Overall, the WARS built 1038 LM-57 from 1957 to 1969. Then this car was replaced in series production by the more modern LM-68 four-axle vehicle that could drive in traction. The LM-57 trams ran in Leningrad, Kiev , Tashkent , Gorky , Arkhangelsk , Kazan , Saratov , Magnitogorsk and Nizhny Tagil from 1957 to 1986. Due to its streamlined shape and many chrome-plated parts, the LM-57 was given the unofficial nickname "Stiljaga" ( Russian Стиляга , the dandy).

In the late 1970s and early 1980s, the management of the Soviet transport company took the vehicles out of service as obsolete. The discarded wagons were almost all scrapped; only two LM-57s have been preserved as museum exhibits to this day. The roadworthy LM-57 is exhibited in the St. Petersburg Tram Museum, the other vehicle is a standstill exhibit in the Electric Transport Museum in Nizhny Novgorod.
