HazMat crew clearing train derailment scene in Spring

SPRING, TX (KTRK) -- Crews are working to remove a train that derailed Monday afternoon in Spring.

Six cargo cars ended up just feet away from spilling into the 2600 block of West Hardy.

Grain was tossed everywhere, and the rear locomotive car was left on its side, leaking diesel. Officials say the engineer wasn't hurt.

Rhonda Watson sitting in her car, waiting for the train to pass.

"As I look at the caboose, it is like wobbling," Watson said.

That wobble quickly turned into a tumble.

"It was going it just like dominoes effect," she said.

Sources close to the investigation say Union Pacific is looking into wether excessive heat caused the tracks to expand.

Crews now working into the night, cleaning up and hoping to get things back on track by morning.
