Firefighters from several departments responded to the North Carolina Transportation Museum in Spencer on Saturday morning after it was reported that several rail cars were on fire. The fire was reported just after 7:00 am. The burning cars were located on a series of tracks on the back side of the museum property. They appeared to be old and unrestored cars. The burning cars were located on a rail line that was between other lines, so firefighters had to bring hoses beneath rail cars that were parked on the other line. Firefighters had to crawl between and beneath rail cars to get to the burning cars. Fire officials on scene pointed out that this is the third suspicious fire in the last three days. Rowan County Fire Division Chief Deborah Horne said that a joint investigation is currently underway.
