Knoxville (AP) -- Fire officials in Knoxville say a fire that burned up the slope of Sharp's Ridge within the city might have been started by sparks from a train's wheels.
A witness told firefighters there had been sparks shortly before the blaze broke out Monday. Consuming about 100 acres of brush on the steep ridge and threatening broadcast towers and a cable TV "dish yard" atop it.
The Knoxville Fire Department and US Forestry Division firefighters worked to subdue the fire, which began around 3:00 p.m. Monday. It took about six hours to contain the fire.
