Police say a freight train transporting petrol got caught in flames after hitting a lorry at a crossery in the US state of Texas.
Footage of the incident in the city of Cameroon in Milam County showed a cloud of black smoke throughout the sky.
Police said the surrounding houses had to be evacuated and at least one property destroyed by the fire.
The driver of the car and the occupants of the vehicle went uncontrolled and no one was reported injured.
Milam County Sheriff Chris White told reporters on Tuesday, “Luckily, everyone seems to be fine,” adding that “there was no more danger at this point” and the focus was to “get the fire out and clean up the mess” to do”.
According to local media reports, at least three sections of the train caught fire and some units left the tracks.
Mr White said the train was carrying “some dangerous material” in the rear trucks, and a section was cut off and driven away from the fire.
“By the grace of God we survived on that one,” he said, without giving further detail to the material he was referring to.
Along with petrol, the train was also reportedly carrying coal.
Mr White said several fire departments were deployed at the scene, but the explosion was very hot when the crew first arrived, adding that they were hoping to extinguish the fire using “heavy foam”.
He The train that described the lorry hit as an 18-wheel “flatbed” vehicle, and said there was no indication that it was transporting anything at the time of the accident.
Police said emergency services were made aware of the incident at around 06:40 local time (12:40 GMT).
Many properties in the area were evacuated as a precautionary measure and some roads were blocked while people were urged to evacuate.
The cause of the collision, described by police as a regular road crossing with obstacles, is not yet clear.
