ABSTRACT: Gauge widening resulting from a loss of adequate rail restraint is one of the major track failure modes and the cause of a large number of derailments. A recent field and laboratory test program conducted by the Transportation Systems Center aimed at the determination of minimum rail strength capacity as influenced by tie and fastener condition resulted in the development of criteria and rail strength capacity limits for the prevention of excessive gauge widening.
