COMPARISON OF EFFECTIVENESS OF FREIGHT CAR ROLL CONTROL DEVICES

The expected cost of derailments attributable to excessive car roll over a period of time can be reduced by various modifications to the car purporting to restrain wheel lifts and stabilize the car in roll. The decreased derailment cost over this period can be traded-off against the installation and maintenance costs of the modifications over the same period to find an optimum balance, i.e. maximum rate of return on investment in roll control devices. For open top hopper cars, double Barber side coils or stiffer A-3 springs were found to be most economic. For covered hopper cars, the Roll Stabilizer or 2 Holland snubbers per spring group were found to be the optimum solution.
