FLINT, Mich. (AP) _ A fire inside a propane-filled train car burned out Saturday, ending a tense 24 hours in which scores of homes were evacuated, two schools were closed and an interstate was shut down.

No injuries were reported.

Flames were spotted spewing from a valve in the tanker at the CSX rail yard Friday morning.

Fire officials, fearing it would ignite a half-million gallons of propane in 54 other cars or explode, ordered 600 people from their homes and shut down nearby Interstate 475.

Early Saturday, firefighters started a ``vent and burn'' procedure _ explosives were used to blow holes in the top and bottom of the car to release pressure and gas _ that allowed the fire to burn out more rapidly, Fire Chief Theron Wiggins said.

Residents were allowed back into neighborhoods near the rail yard at about 2:30 a.m.
