An Amtrak train traveling from Los Angeles to Chicago crashed in northern Missouri Monday.

Amtrak says the train, eight cars and two locomotives with 243 passengers, crashed in Mendon, Missouri at 1:42 p.m. when it hit a dump truck at a public crossing.

The train was headed to Fort Madison, Iowa before reaching its destination in Chicago. Amtrak says there are early reports of injuries but did not say how many or how serious they were.

The westbound train from Chicago back to Los Angeles has been canceled tonight.

Photos posted to Twitter show the train cars on its side with passengers helping others get out of the train.
