Railroad Passenger Ride Safety

摘要

Safety requirements for high cant deficiency rail passenger service address the dangers of vehicle derailment, track damage and unreasonable risks to standing passengers of falling. Safety criteria concerning vehicle derailment and track damage have been well developed. Those applicable to passenger vehicle test data are discussed, and the vehicle overturning safety criterion is shown to be the most restrictive. A literature search of ride criteria and research was conducted. The findings presented show that most criteria address ride comfort rather than ride safety. Objective experiments, described in the literature, relating the ability of test subjects to maintain equilibrium under various acceleration environments are described. Ride safety criteria are recommended which are based on the published experiments, recent vehicle acceleration measurements and railroad operating practices.
