The Utah Transit Authority is investigating why the crossing gates were in an upward position at an intersection where a FrontRunner train hit and tore apart a FedEx cargo semitruck on Saturday.
Police dashcam video of the crash in North Salt Lake shows the gates were up and the flashing lights and bells were not activated when the train struck the truck, UTA said in a Tuesday news release.
When there is a power outage or lack of signal, the release says, crossing gates are programmed to default to the "down and active" position as a safety precaution.
The gates at the intersection, about 1100 North and 100 East, had been affected by severe ice and snow conditions that day and had successfully defaulted to the "down and active" position, the release says. But after an employee arrived at the location, the gates moved to the upward position and remained up as the crash occurred.
