利用前苏联《牵引计算手册》的有关公式，确定出无缝线路及轴重增加对重载牵引货物列车基本阻力的影响程度。并以此来修正全滚动轴承Ｃ６２型货车的单位基本阻力，用来计算重载列车的阻力。讨论并确定了牵引５０００ｔ及６０００ｔ的内燃机车功率及轴式。
Using the relevant formula of “traction calculation manual” in the former Soviet Union, the influence of the increase of CWR and axle load on the basic resistance of heavy haul freight trains is determined. And in order to amend the whole rolling bearing C62-type truck basic unit resistance, used to calculate the resistance of heavy-haul trains. Discusses and determines the traction 5000t and 6000t diesel locomotive power and shaft.
