Exhibit description

Shunting diesel locomotive TEM1-0026

Engineering thought

The first type of shunting locomotive was built on the proven diesel locomotive type 3₀-3₀ of the TE1-20 series and new developments implemented on the mainline diesel locomotives TE-3.

The TEM-1 diesel locomotives used a bonnet-type body and three-axle bogies of the TEZ diesel locomotives. The body rested on each bogie through four side supports, and the traction and braking force from the bogie to the body was transmitted through the central kingpins. The locomotives were equipped with a four-stroke, six-cylinder 2D50 diesel engine with a gas turbine supercharger. This diesel engine developed a power of 1,000 hp.

Exhibit equipment

The diesel locomotive consisted of a main generator, traction electric motors, a two-machine unit and electrical devices. It also had a fuel tank, a fan reducer, refrigerators and a cooling fan for the traction electric motors.

The service weight of the locomotive was 126 tons. The reserves of fuel (5,500 kg), oil (400 kg), water (950 kg) and sand (2,000 kg) allowed the locomotive not to go into equipment for ten days. Which is extremely important for a shunting locomotive, most often tied to work at the station. The design speed of the locomotive was 90 km/h.

Lightweight design

The bonnet locomotives had only one control cabin, which simplified and reduced the cost of the design, and provided easy access from the driver's platform to the locomotive units. The driver in the locomotive cabin always sat on the right side in the direction of travel, so he could see the signals standing to the right of the tracks.

Replacement of steam locomotives

In 1958 the plant produced the first diesel locomotive TEM1-0001. TEM1 locomotives were built throughout the period from 1958 to 1968. A total of 1,946 units of this series were produced. In June 1964 the Bryansk Machine-Building Plant produced the thousandth diesel locomotive of this series.

TEM1 diesel locomotives were used for shunting work at many stations, and also replaced steam locomotives on some industrial and sidings.

In the museum

The Russian Railway Museum displays the diesel locomotive TEM1-0026, one of the first shunting diesel locomotives on the October Railway. It was built in 1959 and had a driver's cab with slanted walls. Later, diesel locomotives were built with vertical straight walls.

Historical context

After the war, the development of diesel locomotive production followed the path of creating bonnet locomotives. They had only one control cabin - this simplified and reduced the cost of the design, and also provided easy access from the driver's platform to the locomotive units. Most often, the cabin was shifted from the center of the locomotive to one of the ends. This was due to the fact that under the longer hood there was equipment for cooling water and oil, and then there was a diesel generator unit. Under the small hood were batteries. There were two control posts in the cabin (on the left and right sides), and the driver used them depending on the direction of travel. The driver in the locomotive cabin always sits on the right side in the direction of travel - this way he sees the signals standing to the right of the tracks.

A similar scheme took root on all shunting diesel locomotives from D^A and TE1-20 to modern machines.

TEM1 locomotives were used for shunting work at many stations, and also replaced steam locomotives on some industrial and sidings.

Starting with locomotive #0390, the driver's cab was made without beveled side walls, as was previously done on TEM2 locomotives. And starting with locomotive #0950, they stopped installing buffers.
