Residents are back at home after an evacuation prompted by a train derailment in the West University area of Houston on Monday night.

At least one of the train’s cars contained Liquefied Propane Gas. Four hopper cars, carrying wheat and lumber, were on their sides along the track.

The LPG car was upright, but fire officials called for an evacuation as a precaution. A Union Pacific spokesman said in all seven cars derailed; four on their sides and three still up right but off the tracks.

Officials confirmed that the LPG was actually empty, but had not been cleaned and contained residual LPG product.

The derailment occurred on a Union Pacific rail line near the intersection of Community and Judson. The evacuation covered a three-block area along Community between Judson and Bissonnet.

In addition to the 20 nearby homes that were evacuated, the Bissonnet was shut down at the railroad crossing. That portion of the road had yet to reopen as of 10 p.m. Residents were allowed back into their homes about 9:30 p.m.

CenterPoint Energy crews were called in to remove power lines to allow Union Pacific crews the ability to get heavy equipment in to upright the derailed train cars.
