Firefighters are battling a brush fire along U.S. 1 in north St. Johns County after a passing train shot sparks into dry grass along the rail line.
Trains have caused multiple fires along U.S. 1 Friday, but most were small and quickly handled. St. Johns County Fire Rescue says the fire along U.S. 1 a half mile south of Pine Island Road is by far the largest.
A Florida Forest Service tractor is on scene creating a fire line. No homes are threatened. No injuries have been reported.
