Crews are trying to keep a freight train from falling into the Trinity River near Livingston after a trestle buckled overnight.
A 60-car Union Pacific train was crossing the bridge when a concrete support shifted and a span slipped off its support. The tracks separated in two places, causing freight cars loaded with plastic pellets to slip off their tracks, spilling some pellets into the river.
Officials say the pellets aren't hazardous. No injuries were reported in the incident, and the derailed train remains perched precariously on the bridge.
