The 1993 Big Bayou Canot train wreck was the derailing of an Amtrak train on the CSXT Big Bayou Canot bridge in northeast Mobile, Alabama, USA, on September 22, 1993. It was caused by displacement of a span and deformation of the rails when a formation of heavy barges had collided with the bridge eight minutes earlier. Casualties were 47 killed and 103 injured.
