TGM23 series diesel locomotives

TGM23 (diesel locomotive with hydraulic transmission, shunting, 23rd type) is a serial Soviet three-axle diesel shunting locomotive with hydraulic transmission.

History of creation

In 1962, the Murom Diesel Locomotive Plant. F.E. Dzerzhinsky built the first experimental three-axle diesel locomotive TGM23-001. In 1963, the plant manufactured three more experimental locomotives of the same type. The new diesel locomotives differed from their predecessors – TGM1 diesel locomotives, which had the same axial formula 0-3-0; at the same time, they retained a significant amount of equipment previously used in diesel locomotives of the TGM1 and TGM21 series.

diesel oil – 120 kg.




Significant differences from serial diesel locomotives were made by the factory in 1969, two experimental locomotives, designated TGM23A-001 and TGM23A-002. Modernized diesel engines 1D12N-500M were installed on these diesel locomotives, which, compared to the diesel engine 1D12N-500, had a higher boost pressure and a number of changes in the design. In hydraulic transmission, two hydraulic units were used instead of three, reverse-mode mechanisms of new construction were used. Has also undergone changes in the exhaust gas path, and therefore the muffler cover was removed from the top of the front hood. The last change was also made to the design of manufactured locomotives of the TGM23 series. One more diesel locomotive of the TGM23A series, the Murom plant manufactured in 1972 and 1973. They were also assigned serial numbers 001 and 002, but they had fundamental differences from diesel locomotives built in 1969: diesel engine 1D12-400N with a capacity of 400 hp, another hydraulic transmission, a modified body structure with buffer lights mounted in the end parts of cowls, and completely the refitted design of the refrigerator with lateral placement of cooling radiators and blinds.


It was notable for less powerful diesel without supercharging (such diesel engines were installed on TGM1 diesel locomotives), a softer spring suspension and a number of changes in the cooling system. Hydraulic transmission remained the same, used on TGM23. Already during the release of TGM23B, the frame design was changed. The diesel locomotives of the TGM23B series were manufactured from 1973 to 1985, altogether about 3400 units were manufactured.


Export version of the locomotive. It is known about two such cars (numbers 009 and 010), delivered to Germany (Wustermark), where they were designated as TGM23B. The further fate of these locomotives is unknown.


From the original series, these diesel locomotives differed diesel, generator and battery. The diesel locomotives of the TGM23V series were built from 1982 to 1991 inclusive. In 1985, the pilot version of the TGM23V diesel locomotive with hydraulic transmission, having two torque converters with a common turbine shaft, was produced. A total of 2667 copies were made.


The further development of TGM23V, the production of which was discontinued in June 1991. Hydrodynamic transmission with automatic gear shifting is used in the locomotive to realize a greater traction force when starting off and makes longer work at low speeds possible, which is especially important for shunting and industrial diesel locomotives. The driver’s cab is equipped with two control panels and has good sound insulation. From the beginning of the production, the diesel locomotive had a service weight the same as in its predecessor TGM23V – 48 tons, but with the number 212 the service weight of the locomotive was used as in the TGM23B – 44 tons, it became apparent on the series, first of all the diesel locomotive began to write no longer TGM23D48, and TGM23D44. It is with such a weight that the diesel locomotive is produced in small batches to this day, in February 2014, the diesel locomotive with No. 0523 was sent to Kazakhstan.


Variety TGM23D with engine KAMAZ-820.63-320, designed for gas fuel (the norm EURO-4). Gas reserves in a diesel locomotive are stored in special gas equipment. Declared fuel costs are 30% lower compared to diesel; the calculated reduction in the emission of harmful substances into the atmosphere by 2 … 2.5 times (expert evaluation).


Three-section version of the locomotive TGM23D. The documentation of the plant runs as a candy bar. In fact, it consists of three diesel locomotives TGM23D44, united by a system of many units. It can also be operated in two sections and one section.
