What were they doing to the railroad tracks?

Question:
i was driving on the highway which runs along a track for about 15 miles and on a particular stretch of about 150 yards (it was night) there was a fire centered directly in the middle of the tracks...the flames were uniform as if there were a propane line running down the center of the tracks and the were flames about 8 inches apart ...it was in a straight line and perfectly centered and the flames were the same size and intensity....was this some kind of routine maintenance and if so what were they doing...there was a csx vehicle parked on the side of the tracks also so it appeared controlled...this is the first time in 25 years of driving that stretch of track i have ever seen this...anyone?
