The Midland Police Department is investigating what caused a bus to crash into a stationary train Monday afternoon.

At 1:19 p.m. officers with the department were dispatched to a crash near the area of West Highway 80 and South Loop 250 involving a vehicle and a train.

When police arrived at the scene they found that a TRAX Bus had crashed into a stationary Union Pacific train. The driver of the bus was treated on-scene before being transported while in a life-threatening condition. Two passengers riding in the bus were treated and transported with minor injuries.

According to City of Midland spokesperson Sara Bustilloz, police believe at this time that the driver of the bus, a woman, suffered a medical episode before the crash.

As of 6 p.m. Monday evening the driver was listed as in critical condition, according to a City of Midland

.

Initial investigation of the scene appears to show that the bus left the roadway around 200 yards away from the train before crashing into it. According to Bustilloz, police do not believe the bus was travelling at a high rate of speed at the time of impact.

Traffic was not affected as the crash happened away from the roadway, Bustilloz said. The Midland Police Department is taking the lead in the investigation.

According to Union Pacific Director of Corporate Relations and Media Jeff DeGraff, their crews responded to the scene to check both the locomotives and the track for any and all damage from the crash.

Only one of the four locomotives involved was damaged and will need to be repaired, according to DeGraff. The other three locomotives and the track itself were found to be undamaged and operable.

All four locomotives were unoccupied at the time of the crash.

While Union Pacific will not be taking part in the investigation, DeGraff says that they will be willing to help out investigators any way they can. DeGraff adds that Union Pacific wishes for speedy recoveries for those injured in the crash.
