The St. Johnsbury and Lamoille County Railroad (StJ&LC) was a railroad located in northern Vermont. It provided service to rural parts of the state for over a century, until track deterioration and flood damage made the line unusable and uneconomical to repair, which forced the line to close in 1995. Vermont is in the process of converting the roughly 96-mile route from St. Johnsbury to Swanton into a rail trail, known as the Lamoille Valley Rail Trail. Once completed it will be the longest rail trail in New England.

The Portland & Ogdensburg Railroad was a railroad planned to connect Portland, Maine to Ogdensburg, New York. The plan failed, and in 1880 the Vermont section was reorganized and leased by the Boston & Lowell Railroad. In 1886, the Maine and New Hampshire section was reorganized as the Portland & Ogdensburg Railway. That part was leased to the Maine Central Railroad in 1888, and in 1912 the Maine Central leased the eastern part of the Vermont section from the Boston & Maine Railroad, the successor to the B&L.
