An 18-wheeler and Amtrak’s northbound City of New Orleans passenger train collided south of Ponchatoula in Tangipahoa Parish on Tuesday afternoon.

The train’s engineer was taken to a hospital to be evaluated but the truck driver was not injured in the collision, which occurred about 3 p.m. on U.S. 51 just off the Interstate 55 exit, The Hammond Star reported.

Amtrak spokesman Marc Magliari said no passengers on the train were injured in the collision.

The northbound passenger train — which was headed to Chicago from New Orleans — was delayed near Ponchatoula while the Tangipahoa Parish Sheriff’s Office conducted its investigation, Magliari said. Officials with the Tangipahoa Parish Sheriff’s Office could not be reached Tuesday.

The train’s locomotive was damaged in the collision, Magliari said, and a replacement was brought in from New Orleans to continue the train’s journey toward Chicago.

Tuesday’s southbound Amtrak train had already arrived in New Orleans ahead of the collision and other passenger trains were not delayed, Magliari said. It wasn’t immediately clear if the collision had closed the stretch of track to freight traffic.
