A Central Railroad of New Jersey commuter train runs through an open drawbridge at the Newark Bay, killing 48.

The 1958 Newark Bay rail accident occurred on September 15, 1958 in Newark Bay, New Jersey, United States, when a Central Railroad of New Jersey (CNJ) morning commuter train, #3314, ran through a restricting and a stop signal, derailed, and slid off the open Newark Bay lift bridge. Both diesel locomotives and the first two coaches plunged into Newark Bay and sank immediately, killing 48 people and injuring the same number. A third coach, snagged by its rear truck (bogie), hung precariously off the bridge for two hours before it also toppled into the water. As the locomotive crew was killed, the cause of the accident was never determined nor reinvestigated.

The Central Railroad of New Jersey, also known as the Jersey Central or Jersey Central Lines (reporting mark CNJ), was a Class I railroad with origins in the 1830s. It was absorbed into Conrail in April 1976 along with several other prominent bankrupt railroads of the northeastern United States.
