They dont measure it in torque figures. Locomotives have tonnage ratings and the power desk matches up a train with appropriate locomotives based on what subdivisions (lines) the train will be traveling from source to destination. Each railroad has track charts and timetables that list how much trailing tonnage a locomotive is rated for on that subdivision.
