GARY, Ind. - Fire officials in Gary responded to the scene of a freight train derailment at Miller and Hobalt roads Sunday.

Gary Fire Department Battalion Chief Donald Williamson says the two eastbound engines collided early Sunday morning. He says the accident was apparently caused by a faulty switch gear.

Dozens of train cars went off the tracks into the Miller neighborhood.

According to the Chicago Tribune, firefighters had to extricate two people, including a crew member who had a broken leg.

Williamson says the train wasn't hauling hazardous materials or tankers and there are no leaks. He said emergency crews responded as if there were hazardous materials as a precaution.

The cause of the derailment was not known Sunday.
