Penn Station is one of the busiest passenger transportation facilities in the U.S., serving more than 600,000 commuter rail and Amtrak passengers each day. In late March and early April, Penn Station suffered two train derailments within a week of each other. Following both derailments, U.S. DOT’s Volpe Center supported the Federal Railroad Administration by sending mechanical engineer Brian Marquis to take measurements at both sites and conduct a track and equipment data analysis.
