TEM-1, made by joint-stock kompany "Bryansk Engineering Works" (BMZ), was the first serial
shunting diesel locomotive in Russia, although two experimental shunting diesel-locomotives
O-el were made in Russia before the WW2. In the time of the Russian accelerated industrialization
there was a problem, how to utilize the quite useful, but not powerful old steam locomotives,
and the railways usually turned them for shunting. The shunting work was not the main factor
of coal expenditure, and the mass production of shunting diesels required only after 1955.
But in 1957 the BMS got the rush job: the powerful shunting diesel - locomotives pressed 
in need. To accelerate the design and technology preparation, the Bryansk engineers unified
the bogies with serial freight diesel - locomotive TE-3, and used the D50 diesel, designed 
for the produced  after WW2 diesel - locomotive TE-1. In Juny, 19, BMZ build the first TEM-1.<br>
Main technical data: two three-axle bogies, diesel power 1000 hp, max. speed 90 km/h.<br>
