ABSTRACT: This document reviews three phases of a study conducted to evaluate and improve the crashworthiness of passenger carrying vehicles in intercity service. Phase I surveyed the accident data over a period 1966 to 1973 and identified those areas responsible for the mS3jority of accidents involving human injury (both operating personnel and fare-paying passengers). An analysis was also conducted on the structural integrity of a commuter car -identified as the single largest source of injuries in the subject time frame. Phase II extended the structural survey to the caboose and the locomotive cab. Phase III developed a potential design for crash survivable locomotive cab and included both static and dynamic analyses of the crash scenarios. The design is predicated about the provision of a "Survivable Volume".
