Union Pacific crews are in Monahans after two trains were involved in a crash overnight.

According to UP, one train hit the back of another train that was stopped at a train yard. This crash caused the cars to derail and pile up along the tracks.

The train that was hit was unoccupied. A conductor and an engineer were cut out of the second train and taken to Medical Center Hospital where they are now in stable condition.

Contractors are now assembling to begin clearing the scene. The work is expected to continue throughout the day and into the night.

Investigators have also arrived and are working to determine the cause of the crash. That process will include reviews of onboard video.

CBS 7 will continue to update this story as more information is released.
