Grassfires break out along 5200 block of FM1187 and at Stuart Phelps and FM1187.
A large cloud of smoke over an unincorporated part of Tarrant County could be seen miles away on Sunday.
On scene, Tarrant County Sheriff's deputies believe it may have been a result of sparks from a train on the tracks.
Two fires are believed to be responsible for the large cloud of smoke. They broke out along two stretches of FM 1187, southeast of Benbrook Lake.
The smoke was so thick it enveloped nearby homes.
"You could see the flames coming off tree tops when you were up a little further up the road," said Terry Covington. "It got so dense you couldn't see 50 yards."
The fire was across the road from Renee Lewis's home.
"We called 911," Lewis said. There was a lot of smoke, they warned us we might have to take off, packed four of the dogs and went down the road where I could breathe a little better."
The Tarrant County fire marshal is still investigating. No word on how many acres were burned as a result.
