The RZD structure, private sidings and companies need facilities capable of performing shunting operations within the station. For these and other functions, shunting locomotives were created, which differ from train locomotives in efficiency.

Assignment of shunting diesel locomotives

A huge number of different diesel locomotives and electric locomotives run on railway transport. Each of them has its own application, and depending on their technical characteristics, they produce a certain type of work. Each station needs to rearrange wagons from one track to another, supply them to non-public tracks, and comply with the norms for the delivery of local cargo. These tasks are easily handled by a shunting diesel locomotive. If large diesel locomotives of high power, such as 2TE116, T10MK, 3TE116U, are used to supervise trains, then ChME3, TEM2, TGM diesel locomotives are used to perform shunting work, where there is no need to move trains of great weight. Shunting diesel locomotives remain the main means of producing local work at the station. Bryansk produces good quality locomotives, which are used in the Russian Railways structure.

History of Creation

ChME2 was the most common shunting diesel locomotive in the USSR until 1964. But due to insufficient power and subsequent non-fulfillment of the shunting work plan, it was decided to design new, more powerful locomotives of this series. The building was taken over by the Prague factory. In 1964, two experimental ChME3 models were launched on the rails, which passed all the tests perfectly. The diesel locomotive of this model, along with TEM2, is still the most common diesel locomotive for shunting work. Along with ČKD Praha, the Sokolovo plant produced T444 and T449 locomotives, which, due to their limited grip weight, were not widely used. Repair of shunting diesel locomotives should be carried out by specially trained people.

ChME3 specifications

ChME3 shunting diesel locomotive is equipped with a bonnet body and an H-shaped frame. Wheel boxes are completed on one bearing. The spring suspension of the locomotive is equipped with hydraulic shock absorbers. The locomotive is equipped with a six-cylinder four-stroke K6S310DK diesel engine, whose power is 1350 horsepower. The shaft speed is increased to 340-740 rpm compared to ChME2. The diesel is powered by a generator from the battery. Diesel has a considerable weight, which is 13 tons, diesel generator TD-802 weighs 20 tons.

NME3 indicators

• Design weight -114 t.
• The weight of the equipped diesel locomotive is 123 t.
• Fuel capacity - 5000 kg.
• Oil reserve - 500 liters
• Water supply -1100 liters
• Sand supply - 1500 kg.
• Maximum speed is 95 km/h
• Minimum radius of curves – 80 m.

Technical characteristics of shunting diesel locomotives of the TEM series

Diesel locomotives of the TEM1 and TEM2 series are widely used throughout the entire railway network. They are economical, reliable and have good power. The Bryansk Engineering Plant recently released a trial model TEM2M, which already has a 6D49 four-stroke diesel engine, as well as a more advanced cooling system.

No tool can cope with the local work of the station like a shunting diesel locomotive. Photo TEM 2 illustrates the appearance of the locomotive. It can run on curved sections of the track with a radius of up to 80 meters. Full supply of fuel, oil and sand will ensure uninterrupted operation for up to 10 days.

TEM2 is equipped with a PD1M diesel engine with a declared power of 880 kW, in which the speed of rotation of the crankshaft is increased, the air pressure is increased to 0.155 MPa. The PD1M uses a turbocharger, which is driven by exhaust gases. Air purification for the turbocharger is carried out by rotating the air cleaner mounted on the right side of the locomotive. But for air cooling, a finned tubular cooler is used, which functions with the help of a water circuit. A centrifugal fan is used to cool the traction motors. Immediately behind the driver's seat is the battery compartment. On the roof of the locomotive there arehatches of folding type for supply with sand. Shunting diesel locomotive TEM 2 is able to rearrange heavy weight wagons from track to track.

To ensure a favorable temperature in the driver's cab, a heater is used, and there are also foot warmers in the right and left parts of the cab directly at the workplaces of people servicing the diesel locomotive. Due to the good thermal insulation of the cabin, TEM 2 can be used at low temperatures. The control panel is equipped with safety devices, a speedometer SL-2M, a driver's crane for gaining or lowering positions, radio communications, control devices, control buttons for typhons and a pedal for supplying sand under the front and rear carts.

The locomotives of the TEM series have additional equipment that allows the driver to work alone, that is, without an assistant. To do this, the equipment is equipped with a portable control device.

Blinds are provided on the body of the locomotive for cooling water and oil. The fuel is heated with hot water, which comes from a running diesel engine. Since the body is a bonnet type, there is free access to all equipment of the locomotive.

The driver's cab is raised above the frame, which gives a good view. To ensure timely fire fighting and safety, the locomotive is equipped with two fire extinguishers. The driver of a shunting diesel locomotive must have the skills to manage and have the appropriate education.

Technical characteristics of diesel locomotives of the TGM series

The TGM shunting diesel locomotive is used to perform shunting work at the station and private sidings.

TGM-4B is equipped with a 6ChN21-21 diesel engine with a gas turbocharger. The speed, like many competitive models, is 1200 rpm, has 2 modes: shunting and train. The train mode of operation allows you to run within several stations, and the train mode is designed to perform assigned tasks within the station.

In terms of driving performance, the shunting locomotive is equipped with spring suspension mounted on two-axle bogies. Good dynamic properties soften loads and allow good entry into small radius curves. The locomotive is equipped with a manual mechanical brake. The body of the locomotive is made using hatches and foldinghoods for easy access to important parts of the machine.

The interior of the cab is equipped with lamps that signal the location of the driver, who can operate the machine from both sides. The shunting locomotive is operated alone, i.e. an assistant is not required. The cabin has good noise-absorbing qualities. Reliably executed fastenings of the case with a frame muffle any kind of vibration. And the heat-insulating materials used in the manufacture of the body contribute to the operation of the diesel locomotive at low temperatures. The new shunting diesel locomotives have significant differences compared to their predecessors.

Quality assurance in the repair of shunting diesel locomotives

• It is necessary to disassemble and assemble a shunting diesel locomotive with strict observance of technical documentation.
• Requires specialized, expensive equipment.
• Availability of all necessary spare parts and parts.
• Work must be carried out by highly qualified specialists.
• Before starting repairs, it is necessary to develop several options for the production of work.
