This line, of the Edgemoor & Manetta Railroad, left the Seaboard Air Line mainline at Edgemoor and ambled a few miles to a mill in Lando. Its 2.5-mile length was owned by Manetta Mills, the line's only customer. Operations were discontinued July 9, 1975, when the road's steam locomotive was condemned, which is shown on display in Richburg, SC in the picture below. (While Richburg was not on the E&M, it is on the still-active Lancaster & Chester.)
