The locomotives of the SŽD series 2ТЭ10M (German transcription 2TE10M ) of the Soviet Railways (SŽD) are wide-gauge diesel locomotives with diesel-electric direct current power transmission, which are mainly used in freight transport. From 1981 to 1990 the Luhansk locomotive factory delivered 3513 units of this series.
The double locomotives belong to the family of ТЭ10 locomotives and are a further development of the 2ТЭ10B series . The M in the name stands for М одернизация (German: "Modernization"). The changes mainly relate to the control circuits, the locomotive body , which is identical to the 2ТЭ116, and the drive system with the opposed piston diesel engine 10D100 were carried over from the previous series.
Many locomotives were modernized in 2005, with a sixteen-cylinder diesel engine with electronic fuel injection and a more powerful cooling system. This is intended to extend the service life of the locomotives until 2020.
technology
The 2ТЭ10M was characterized by the following improvements over the 2ТЭ10B:
- Possibility to control three sections from one driver's cab
- Possibility to operate one or two sections in idle with the diesel engine speed of drive level 8. This enables the compressor to have a greater capacity when idling and the diesel engine to cool down quickly, because the speed of the cooling air fans is directly dependent on the engine speed
- Larger number of instruments on the driver's desk so that the operating status of the individual sections can be displayed separately. The warning lights for the individual sections are located on a separate control panel
- In the control circuit, the coils of the electromechanical devices were provided with circuits against harmful overvoltages in the control circuit, which typically arise when relay contacts are opened
- Electrically controlled release of the compressed air brake
- Electrically controlled air dryer in the compressed air supply
- Electrical lines between the sections are routed through three sockets, which makes troubleshooting easier
- Changed plugs for the control batteries on some locomotives
- The minus line of the control power supply at the apparatus chamber and at the driver's desk can be separated with a plug, which makes troubleshooting easier
- Radiotelephony between the cabs of the sections.
3ТЭ10М
At the same time as the 2ТЭ10M series, 639 3ТЭ10М with three sections and an output of 6.6 were also created MW. In addition to the end sections of the same construction as the 2ТЭ10М, they received a middle section without a driver's cab. An auxiliary driver's cab with a maneuvering brake valve allows the middle section to be moved on its own, which, however, in contrast to the end sections, cannot be used for hauling trains due to the missing driver's brake valve.
4ТЭ10С
25 locomotives 4ТЭ10С were with four sections and a total power of 8.8 MW delivered. The locomotives were given two middle sections without a driver's cab in addition to the two end sections that were identical in construction to the 2ТЭ10М, as described in the section on the 3ТЭ10М.
2ТЭ10МK
In 1981 the Luhansk locomotive factory delivered a series of 20 locomotives of the 2ТЭ10МK series , which, like the 2ТЭ116, are equipped with the 5D49 diesel engine from the Kolomna locomotive factory . The K in the designation stands for K olomna.
