以古比雪夫命名的科洛姆纳内燃机车制造工厂设计和制造了两台单节4000马力TЭП70新型客运内燃机车的样机(图1)。在五年计划的最后一年(1975年——译注)还要制造几台这种机车。ТЭП70机车的功率比其上一代——ТЭП60、机车要大30％以上,而重量仅增加1.5％。机车较小的轴重——21.5吨保证它能通过国内所有的铁路线。 A prototype of two new 4,000 horsepower TÜП70 passenger diesel locomotives was designed and manufactured at the Kolomna diesel locomotive manufacturing plant named after Gobishev (Figure 1). Several such locomotives were to be built in the last year of the five-year plan (1975). ТЭП 70 locomotive power than its predecessor - ТЭП60, locomotive to be more than 30%, while the weight increased by only 1.5%. The smaller axle weight of the locomotive - 21.5 tons guarantees that it can pass all the domestic railway lines.
