NTSB trying to determine why tractor-trailer stopped on train tracks before deadly West Texas crash

PECOS, Texas (AP) — Federal officials investigating the deadly West Texas collision between at Union Pacific train and a tractor-trailer hauling heavy equipment are trying to determine why the tractor-trailer was stopped on the tracks. Two employees of Omaha, Nebraska-based Union Pacific were killed in the Wednesday crash at a railway crossing in Pecos. The National Transportation Safety Board says the crash derailed the train and caused the heavy equipment to fly into the air and hit a building.
