context_section_description: The M&M Subdivision was the site of the deadliest crash in Amtrak's history.  On September 22, 1993 at 2:45 a.m., a barge lightly struck the line's bridge over Big Bayou Canot near Mobile.  The bridge had been designed as a swing bridge, but the center span was never operational and was not fully secured from movement when it was built.  The impact displaced the span, putting the rails out of alignment.  Amtrak's Sunset Limited crossed the bridge at full speed 8 minutes later and fell into the bayou, killing 47 people.
