The locomotives of the SŽD series 2ТЭ40 (German transcription 2TE 40) of the Soviet Railways (SŽD) were broad-gauge diesel locomotives with diesel-electric power transmission primarily for freight train service. They were among the first diesel-electric locomotives of the SŽD with a 16-cylinder four-stroke diesel engine and turbocharger and can be described as a prototype for the 2ТЭ116 , which was later produced in larger numbers . They were derived from the 2ТЭ10 and were nicknamed Ukraina 2 .
Creation of the diesel engine
The first diesel locomotives of the SŽD in the 1960s were built with two-stroke diesel engines that came from shipbuilding. These were the SŽD series ТЭ3 with the diesel engine 2D 100 and the SŽD series ТЭ10 with the diesel engine 9D 100 or 11D 45 . Due to the performance characteristics and fuel consumption, these solutions were judged to be impractical. The existing diesel locomotives with four-stroke diesel engines ( SŽD series ТЭ1 , SŽD series ТЭ2 ) had the diesel engine type D50, which was already obsolete at the time. Therefore, a two-cylinder cell was designed in the Kharkov locomotive factory in cooperation with the Motor Institute , which was seen as the basis for the future four-stroke diesel engine. The diameter of its cylinders was 240 mm and the piston stroke 270 mm. After the experiment, a sketch project with two variants of the turbocharger was created in 1962 . In the first variant, the original turbocharger should be used, in the second variant, a gas turbine should squeeze out the excess pressure, which meant that lower fuel consumption was expected.
After detailed consultation, the decision was made for the first variant and a 16-cylinder four-stroke diesel engine with a V-shaped arrangement of the cylinders, which was given the designation 16VD70 . The engine developed an output of 3000 hp at an engine revolution of 1000 min −1 , it had a specific fuel consumption of 150 to 155 g / PSh compared to the 160 to 170 g / PSh of the two-stroke diesel engines. This reduced the stress on individual components such as pistons , valves , cylinder heads and cylinder liners . Likewise, there was a greater possibility of heat dissipation, whereby the cooling system could be reduced. On the basis of this engine type, it was possible to create type sizes with different outputs for different diesel locomotives.
Construction of the diesel locomotive and whereabouts
In the middle of 1963, the Kharkov locomotive factory began planning the new two-section diesel locomotive with the D70 diesel engine with an output of 2 × 3,000 hp. The main designer for locomotive construction, Александр Александрович Кирнарский, was responsible for the elaboration. In the middle of the following year, the plant built the first test locomotive, which was given the designation 2ТЭ40-001 and the plant name Ukraina-2 . Apart from the new diesel engine, the new locomotive received the same generator unit and also the same bogies, drive and auxiliary units as the 2ТЭ10 and the ТЭ30 . The face of the vehicle and the bogies had a certain resemblance to those of the Taiga drum later known in Central Europe . The locomotive was able to develop a pulling force of 54,000 kp, the design speed was 100 km / h. At the same time, a single-section passenger locomotive with a speed of 140 km / h was created on the basis of their design.
From 1965 to 1967 the Kharkov locomotive factory delivered four diesel locomotives of this type with the inventory numbers 2ТЭ40.002–005 , which were equipped with other traction motors that were already used with the ТЭП10 and 2ТЭ10Л . The fire extinguishing system for these locomotives has been changed. They also had a different transmission ratio, which reduced the pulling force to 52,000 kp. The locomotives of the series 2ТЭ40 were together with the ТЭП10 the last locomotives from the Kharkov locomotive factory. In 1968 the locomotives were completely handed over to the Ministry of Defense, and the company then specialized in the manufacture of tanks.
In 1965 the diesel locomotive 2TЭ40-001 was handed over to the Yuzhnaya zhelesnaja doroga locomotive depot . The other four machines were also given there in 1968, although the 2ТЭ40-003 was considered to be retired a little later. Given the small number of units, it is hardly surprising that the locomotives did not have a long life; the beginning of the production of diesel locomotives in the Luhansk locomotive factory with the types ТЭ109 and 2ТЭ116 soon made the locomotives superfluous. In 1971 the 2ТЭ40-001 and 2ТЭ40-002 were retired. The 2ТЭ40-004 and 2ТЭ40-005 were put aside by the train service in 1974 and handed over to the track construction.
