3 trains collide near school outside Amarillo, Texas.

AMARILLO (September 25, 2013)--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.

Three freight trains collided in the Texas Panhandle before dawn Wednesday, derailing up to 30 cars and injuring four crewmembers, including two critically.
An eastbound BNSF Railway train rear-ended a stopped train, then moments later a westbound train collided with the two-train wreck, just east of Amarillo, according to the Department of Public Safety. The accident was reported shortly after 4:30 a.m.
"The wreckage was mangled up," said Sr. Trooper Chris Ray.
Joe Faust, a spokesman for Fort Worth-based BNSF, said no hazardous material spilled and that the trains were hauling flatbed cars carrying truck trailers.

Two workers on the first train suffered injuries not believed to be life-threatening. Two crewmembers on the second train were critically injured and transported to an Amarillo hospital, Faust said. Names of the workers and details of their injuries were not immediately released.
