Track Skid
July 21st, 2010
Is an “emergency stop” the fatest way to stop a moving freight train?
I guess when you “lock the brakes down” on a long train you are basically sliding metal on metal as the locked wheels skid down the track. Is it more effective though to have a controlled application of the brakes where the wheels do not lock (is this even possible in an emergency or are you required to hit the emergency stop)? When a lock up does occur, does it mean that all of the wheel sets on the train will experience some degree of damage due to flat spots?
Vehicles have implemented ABS to prevent lock ups. This is because vehicles travel in two dimensions and control is limited if not impossible if thw wheels where to lock
Trains are one dimensional in that they travel along a straight line. To answer youre question, No, it would not be better to have a controlled action to stop the train. The wheels will have negligible “flat spots” or imbalances as the material used has good abrasion, indentation and other properties to reduce the loss of material when grinding between the wheels and the track occur. Friction is the only way to stop the train, so by controlling it or intermittently interupting it will serve no purpose.
