Maine Central Railroad Company The Maine Central Railroad Company (reporting mark MEC) was a former U. S. Class I railroad in central and southern Maine. It was chartered in 1856 and began operations in 1862. By 1884, Maine Central was the longest railroad in New England. Maine Central had expanded to 1,358 mi when the United States Railroad Administration assumed control in 1917. The main line extended from South Portland, Maine, east to the Canada–United States border with New Brunswick, and a Mountain Division extended west from Portland to Vermont and north into Quebec. The main line was double track from South Portland to Royal Junction, where it split into a "lower road" through Brunswick and Augusta and a "back road" through Lewiston which converged at Waterville into single track to Bangor and points east. Branch lines served the industrial center of Rumford, a resort hotel on Moosehead Lake, and coastal communities from Bath to Eastport.
