ABSTRACT: Advancements in the design of rail cars can potentially prevent the structural collapse of space occupied by a cab car engineer during a train collision. With adequate survival space maintained, the next crashworthiness objective is to minimize the consequences of any resulting secondary impact between the engineer and the control stand. A conceptual Engineer Protection System (EPS) has been developed to meet these design objectives and requirements, using finite element analyses and component-level tests. The system was fabricated and dynamically tested using an instrumented Hybrid III 95th percentile male anthropomorphic test device (ATD).
