KIRBY, Texas -- A train derailment in Kirby kept crews busy early Thursday morning.
The derailment happened off FM Road 78 before 1:30 a.m. Thursday. News 4 WOAI was told a Union Pacific train car toppled over at a refueling depot.
The accident blocked the tracks for several hours. Since it was confined to the depot, no traffic in the area was affected.
Investigators are still trying to figure out what caused the train to go off the tracks.
