The Waterville Railway, claimed to be the shortest railroad in the United States, ran from a connection with the Mansfield Branch (also abandoned) of the Great Northern Railway at Douglas, to Waterville to the northwest, at a length close to 5 miles. The line was built in 1910 using the labor and equipment of the GN.
In 1948, the line suffered from flooding and washouts, and was consequently never rebuilt; abandonment came in 1954.
