Aug 12 (Reuters) - A Union Pacific Railroad

train derailed two miles east of Gordon, Texas, on Tuesday, the

company said, and emergency responders said the derailed cars

did not appear to be leaking their contents.

The emergency responders in Palo Pinto County said that,

nonetheless, the derailment was "being treated as a HazMat

situation."

"At about 2 p.m. CDT today, approximately 35 Union Pacific ( UNP )

cars derailed," the company said in a statement.

It was not clear what caused the derailment just outside

Gordon, a town with a population of 460 located about 95 miles

(153 kilometers) west of Dallas.

The company did not immediately respond to a request for

comment on what materials were being carried in the derailed

cars.

Officials with the Palo Pinto County Emergency Services

District 1 said the derailment had sparked some small grass

fires, which firefighters were working to control.

"At this time, there are no confirmed hazardous material

leaks," the emergency officials wrote on social media.

They said that nobody was hurt in the incident and all

railroad personnel had been accounted for.

The railroad said additional crews were in transit and an

incident investigation was underway.
