该机车的试运是在列宁格勒——塔林铁路区段内进行的,这条铁路长为368公里,是一条世界上采用最大功率客运内燃机车的铁路。TЭΠ75型机车是由科洛姆纳机车厂制造的,并于1978年在谢宾卡城展出的,但到目前为止才正式宣布这台试验型机车可以牵引列车。运行状况由一组工程师严密地监视着。 TЭΠ75型机车最高速度为160公里/小时,比目前苏联铁路上所采用的任一内燃机车的速度都高。一台6000马力柴油机驱动一台牵引交流发电机,还有一台列车取暖用的装在同一壳体内的800千瓦交流发电机。电流经过整流后,供给六根动轴上的直流电动机。机车
The trial run of the locomotive was carried out within the Leningrad-Tallinn Railway Section, which is 368 km long and is the world’s largest railway with the largest power passenger diesel locomotive. The Tܶ75 was built by the Kolomna Locomotive Works and was exhibited in the city of Shepbacca in 1978, but until now it was officially announced that the pilot locomotive could tow the train. Health was closely watched by a group of engineers. The maximum speed of the TÜÖ75 locomotive is 160 km / h, which is higher than any of the diesel locomotives currently used on the Soviet railway. A 6000 horsepower diesel engine drives a traction alternator and a 800-kilowatt alternator for heating the train in the same housing. The current is rectified and supplied to the DC motors on the six moving axes. locomotive
