TREAD BRAKING VERSUS THE WHEEL
Many railroads, when initiating 100-ton car unit train operation, have experienced wheel problems. The bulk of these problems have centered around the tread of the wheel, and have taken the form of what has been described over the years as 'shelling'. The purpose of this paper is to determine if there are any links between 'shelling' and tread braking. While it has been shown that the detrimental effect can be catastrophic, the converse has also been shown that identical cars operate with no problems. The report makes several recommendations, including: (1) Through strong operating rules, use of locomotive dynamic brakes should be required to control or decrease the speed of the train. (2) Empty-load brake equipment should be used on the cars.
