On February 6, 1951, a Pennsylvania Railroad train derailed on a temporary wooden trestle in Woodbridge, New Jersey, United States, killing 85 passengers.

on Tuesday, February 6, 1951, Pennsylvania Railroad (PRR) Train #733, nicknamed "The Broker", left Exchange Place in Jersey City.

[3] 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.

[4] However, the PRR at the time did not require any signal to be in place to warn approaching trains about the diversion, believing the verbal notification to be sufficient.

[2] Before "The Broker" left Jersey City, conductor John Bishop reminded engineman (that is the Pennsylvania Railroad's referring for engineer) Joseph Fitzsimmons about the speed restriction.

At 5:43 pm, the tracks, which were not secured to sleepers but resting in shallow grooves on the top of the trestle, shifted under the massive locomotive, and eight of the train's eleven passenger cars derailed.
