Three freight trains have collided in the Texas Panhandle, derailing up to 30 cars and leaving four crewmembers hurt including two with critical injuries.
The Department of Public Safety says the accident happened before dawn Wednesday just east of Amarillo.
Sr. Trooper Chris Ray says an eastbound train rear-ended a stopped train, and that a westbound train then collided with the two-train wreck.
BNSF Railway spokesman Joe Faust says two crewmembers on the first train have non-life threatening injuries and that two from the second train are critically hurt.
Faust says the trains were hauling flatbed cars carrying truck trailers and that no hazardous materials spilled.
Authorities are trying to determine what caused the accident.
