UPDATE: All three firefighters were released from the hospital Wednesday night. Lieutenant Greg Goettsch of the Abilene Fire Department said they will have to follow up with a doctor before returning to duty.

The fires were extinguished Wednesday afternoon, but the cause is still under investigation. Witnesses said the fire started from sparks flying from a passing train.

Firefighters are trying to repair the brush truck that flipped. They will know whether or not the truck is repairable in several days.

Molly Ann Flores was driving down Treadaway Boulevard around 3:30 p.m. Wednesday when she noticed smoke rising from behind her home on the 1400 block of Cottonwood Street on the northeast side of Abilene.

Two grass fires, which were burning near the railroad tracks more than 50 feet away from Flores’ house, consumed more than 10 acres of land and sent three firefighters to the hospital.

Firefighters were trying to douse the first fire when the second started four blocks north from the first fire. A brush truck with three firefighter passengers flipped on its way to the second blaze. All three firefighters were taken to Hendrick Medical Center and were treated for “mostly bumps and bruises,” said Lieutenant Greg Goettsch of the Abilene Fire Department.

The cause of the fires is under investigation.

“It could be transient activity along the tracks, but we haven’t ruled out anything yet,” Goettsch said.

Traffic was briefly stopped on North 10th Street but not for the duration of the fire, which lasted approximately three hours.
