One person has been injured and three are missing after two freight trains collided head-on near the Texas town of Panhandle.
The crash, which happened around 8:40am local time, sent huge clouds of thick black smoke billowing into the sky.
Residents described hearing a screech of brakes, followed by what sounded like an explosion.
Billy Brown, a farmer who lives in the area, said he saw a fireball erupt after the collision.
“I don’t know how anyone survived,” said Mr Brown. “It’s terrible. I’ve seen a number of train wrecks but I’ve never seen one like this.”
The eastern district of Panhandle has been evacuated as fire fighters battle to put out the blaze. Parts of the passing road have also been shut.
It was not clear what was in the trains at the time.
The railway operator, BNSF, previously had an accident involving a collision with another train in December 2013 in Keithville, LA.
Two locomotives and 11 cars from the train derailed when it met head-on with a Union Pacific train.
The likely cause was eventually reported to be the BNSF conductor’s improper positioning for a switch onto a side track, according to the rail safety board.
