An official says cleanup is under way in West Texas after a freight train carrying hazardous materials derailed. Some residents were evacuated temporarily but no chemicals were released.

A Union Pacific spokesman says the train was traveling from Louisiana to California when 86 cars jumped the track late Tuesday night. The two-person crew was not injured.

About a dozen homes were evacuated near Alpine, Texas, about 220 miles east of El Paso. Residents are returning home after officials determined no chemicals had leaked.

Some cars were carrying a solvent used in the chemical and pharmaceutical fields.

The cause of the derailment is under investigation.
