"The Office of Research and Development of the Federal Railroad Administration (FRA) is investigating how to improve rule provisions addressing the safe, timely, and effective emergency evacuation of occupants from rail passenger vehicles in various emergency scenarios. A variety of evacuation concepts, strategies, and techniques for applicability to U.S. rail passenger cars are being investigated and evaluated. Under the sponsorship of the FRA, and with the partnership of the Washington Metropolitan Area Transit Authority (WMATA) and New Jersey Transit, an Emergency Evacuation Simulator (Rollover Rig) for passenger cars was constructed at the Carmen E. Turner Training Facility, located in Landover, MD. The original idea for this rotating rail car came from a British design built to evaluate evacuation equipment and scenarios. The FRA Simulator can 'roll' the car 'over' in 10-degree increments in place to simulate rail car positions after derailments or other rail accidents. The Simulator is intended for use as a training tool by emergency response organizations, and for equipment designers to evaluate different types of emergency equipment."
