2TE116 (2-section diesel locomotive with power transmission, type 116) – a series of main two-section freight diesel locomotives with electrical transmission, produced in the USSR and Ukraine, at the Lugansk Diesel Locomotive Plant (PJSC “Luganskteplovoz”, formerly VZOR – Voroshilovgrad October Revolution Plant).
One of the most common freight diesel locomotives in Russia and the post-Soviet countries. The railroad also received the nickname “Hunchback” (for the characteristic shape of the roof), “Fantômas” and “Boeing”.
The main directions of development of the national economy of the USSR for 1976-1980 included the development of the production of two-section mainline diesel locomotives with a capacity of up to 8,000 horsepower. The prototype for the creation of such locomotives was the diesel locomotive 2TE116, which marked the beginning of a new family of freight locomotives, the first sample of which was built in 1971

The main two-section diesel locomotive 2TE116 with a power of 2 × 3060 hp, intended for the cargo service on the USSR railways, was created by the diesel locomotive plant named after October Revolution (Voroshilovgrad), together with other enterprises: diesel locomotive building plant them. Kuibyshev (Kolomna), the plant for transport engineering them. Malysheva, “Electrotyazhmash” them. Lenin, “Elektromashina” (Kharkiv), as well as sectoral institutes of diesel locomotive engineering (VNITI) and the Ministry of Railways (Central Research Institute of Railway Transport Ministry).
In total, from 1971 to 2016, 2176 copies of all versions of the 2TE116 diesel locomotive were produced. The largest number of diesel locomotives of the series was produced in the 1980s and 2012, 2013. Since the beginning of the 1990s, after the collapse of the USSR, the production of diesel locomotives has significantly decreased from several dozen per year to several locomotives per year, and for some years locomotives have not been produced. However, since 2004, the production volume has increased significantly and continued through 2007, after which the plant switched to the production of an improved modification of 2TE116U. At present, the production of diesel locomotives of the 2TE116U series is minimized due to the military conflict in the Donbas.
2TE116G – gas-powered diesel locomotive. It consists of three sections – two diesel (with cabs, as in the usual diesel 2TE116) and one cryogenic – with a gasifier (without control cabs). The diesel locomotive used 1GDG gas-diesel generator with electronic control, regulation and protection of diesel engines (SKRZD-3), additional systems for water and gas supply, control of gas equipment, control and protection, alarm, gas activation (shield-2-1 ), ventilation of electric compartments and gas equipment compartment, remote uncoupling of diesel sections from cryogenic. Built in 1988.
2TE116M is a modification of the diesel locomotive 2TE116 (in particular, 2TE116M-140, 316, 317), during which a rheostat brake was installed, which was subsequently installed on serial versions 2TE116 and 2TE116U. The electric circuit of this diesel locomotive is characterized by the preservation of the power of three-phase asynchronous electric motors of auxiliary machines from the traction generator and during electric braking, as well as control of the electric braking mode using the automatic braking control system (CART). The system allows, in particular, to automatically maintain a given speed on descents.
2TE116A is a diesel locomotive, which was designed for maximum unification with the new diesel locomotive 2TE121, which was under construction in the 80s, and was also the prototype of the 4TE130 diesel locomotive.
2TE116UP – passenger-cargo modification, in 1996 was built a single copy. The power of the diesel engine is increased to 3600 hp, the diesel locomotive is equipped with a rheostat brake and an electric heating system for the train. The traction unit consists of a traction and auxiliary synchronous generators mounted in one housing. An auxiliary generator through a rectifier provides power to a passenger train with a voltage of 3000 V DC with a capacity of 575 kW from each section in nominal mode. The thrust force of the long-term regime is 2 * 323 kN (2 * 33 tf), the design speed is 120 km / h.
2TE116U – “advanced”. Modification of the 2TE116 locomotive for the Russian Railways, equipped with a new cabin (of the type 2TE126 / 136) with the installation of air conditioning, with resistive braking, with an increased diesel output of 3,600 hp and microprocessor control and diagnostics system (MSU-TP).

3TE116U – three-section version 2TE116. The structure has an intermediate section, in which the head part has a control cabin of a simplified design with an intersectional transition.
2TE116UM – modification for Mongolia with an improved charge air cleaning system and an increased power of diesel engines. Has its own numbering, started again from 001. Built 31 copies. It is worth noting the diesel locomotive 2TE116U-0062 from increased to 4100 hp power of diesel engines produced for the Mongolian railways. Due to this change, the rear part of the roof of the sections is slightly modified; the locomotive received the additional nickname “two-humped”.
2TE116UK – for PromTransManagement, LLP, without microprocessor control system, power 3060 hp, without air conditioners.
2TE116UD is a modification with a diesel engine manufactured by General Electris (GEVO V12 produced by GE Transportation with a capacity of 4,215 kW and a traction unit A723MU2 manufactured by SE Plant Electrotyazhmash).
2TE116UR – modification with a diesel engine company MTU.
