The driver should use the engine to advance the tractionresistanceto reduce the speed, slow progress, and try to avoid the pursuit of the steering and brakes.
驾驶员应提前利用发动机牵引阻力作用来降低车速、缓慢前进，并尽量避免猛打方向和急刹车。

Low atmospheric pressure and temperature of surrounding air are both effected to locomotive output power at wheel rim and train resistance with diesel traction.
低气压和低气温均构成对机车轮周功率(内燃牵引时)和列车阻力的影响。
3
Rail must provide continuous, smooth, least resistance of rolling surfaces and good adhesion of tractionto the train wheels.
