Railroad officials helped shuttled firefighters from Auburn and New Gloucester to a pair of fires along the tracks near Brown’s Crossing Wednesday afternoon. The first fire, reported at abut 1:45 p.m. and believed to have been caused by a passing train, was roughly 100 feet long by 100 feet wide. It took a half-dozen firefighters 20 minutes to snuff it out with hand tools. Railroad officials riding up and down the tracks soon found a second fire a mile away. That one covered roughly 2 acres. Crews from St. Lawrence & Atlantic Railroad shuttled 13 firefighters from Auburn and another 10 from New Gloucester to the scene of the second blaze near Cobb’s Crossing. Firefighters remained at the scene until about 4:30 p.m. A pair of officials from the Maine Forest Service went out to investigate. A short time later, that agency declared a red-flag warning for wildfire danger in the area.
