A railroad bridge partially collapsed early Monday causing a train to derail in northeast Houston.

Houston police were on the scene just after midnight after a Union Pacific train came off its tracks closing both sides of Wayside Drive at Liberty Road.

"Wayside just south of the Loop will be closed in both directions for the next several hours," police tweeted. "Union Pacific is working to clear a derailment."

The bridge partially collapsed and might have caused the derailment, according to OnScene TV.

Houston Metro rail service in the area was affected, according to the transit agency.

No other information is known at this time.
