On February 6, 1951, a Pennsylvania Railroad train derailed on a temporary wooden trestle in Woodbridge, New Jersey, killing 85 passengers. It remains New Jersey's deadliest train wreck, the deadliest U.S. derailment since 1918, and the deadliest peacetime rail disaster in the United States. Description Around 5 p.m. on Tuesday, February 6, 1951, Pennsylvania Railroad Train No. 733 left Exchange Place in Jersey City. An express train to Bay Head via the North Jersey Coast Line, No. 733 was crowded that day due to a labor strike on the nearby Jersey Central Railroad. It carried over 1,000 passengers in 11 cars drawn by PRR K4 4-6-2 steam locomotive No. 2445. That afternoon, rail traffic through Woodbridge was being diverted onto a temporary wooden trestle and a shoofly near Fulton Street, allowing laborers building the New Jersey Turnpike to work on the main line. A notice had gone out to train engineers in late January: after 1:01 p.m. on February 6, they were to proceed through Woodbridge not at the normal but at . Before Train No. 733 left Jersey City, conductor John Bishop reminded engineer Joseph Fitzsimmons about the speed restriction. It was not the railroad's practice to install warning lights in such cases, and Fitzsimmons failed to slow the train as it approached Woodbridge. Bishop, alarmed at the train's speed, tried to pull the emergency cord, but the crush of passengers made it impossible. The train was traveling faster than when it reached the curve approaching the trestle, according to a subsequent inquiry. At 5:43 p.m., the tracks shifted under the massive locomotive, and eight of the train's eleven passenger cars derailed. The first two cars fell on their sides. The third and fourth cars crashed into each other as they hurtled down a embankment. It was in these two cars that most of the 85 deaths occurred. The fifth and sixth cars were left hanging in mid-air over a street that glistened from rain. Some passengers may have jumped to their deaths, believing they would land in water. The accident occurred in a heavily populated area, so help soon arrived. Neighbors opened their houses and businesses to those in need. The critically injured were taken to nearby hospitals. Although Fitzsimmons initially claimed that he had been traveling at only , the inquiry estimated that the train's speed was between . The report concluded that the wreck was caused
