| Abstract |
| | The modern freight car truck is a relatively simple structure which provides for weight transfer between the car and track, maintains the proper positioning of the wheels with respect to the rail, contains the suspension elements for isolating the effects of wheel/rail forces and acts as a support for the brake. The number of freight car truck components which fail and cause accidents is low with respect to the number of cars in the railroad fleet. Most freight car truck components function as safe-life rather than fail-safe structures requiring a conservative approach to their design. The reliability problem is complicated by the practical difficulties of making adequate field inspections. Current efforts to improve reliability include gaining a better understanding of complex wheel failure phenomena, improving design and performance specifications, developing new systems for wayside inspection and developing new truck designs for the reduction of wheel/rail forces. 10 ref.-AA |
