frictional force
The force required to overcome friction when a set of tubs or a run of wagons is hauled along a level track at uniform speed. For ordinary pit tubs the frictional force is about 40 lb/st (20 kg/t) load, and for mine cars or wagons it is about 28 lb/st (14 kg/t) load. This resistance is sometimes called traction.
