Crews worked Tuesday night and through the morning Wednesday to clear derailed cars and upright locomotives after two Union Pacific freight trains crashed Tuesday afternoon in Mid-Missouri.
As of Wednesday afternoon, UP officials said track repairs also had to be done in the area. If all went well, they hoped the tracks would re-open late Wednesday night.
The cause is still under investigation.
Authorities said the trains derailed after one train hit the other from behind in Morrison, near the Gasconade/Osage county line.
The conductor of one of the trains was taken to a hospital for treatment of minor injuries.
Nine rail cars and two locomotives derailed. The trains were carrying a variety of cargo, and there was no concern about hazardous materials leaking.
Amtrak passenger rail service bused passengers around the derailment to get them to their destinations.
