Tapeworm Railroad
The Tapeworm Railroad was a railway line planned by Congressman Thaddeus Stevens and nicknamed by opponents ridiculing a lengthy serpentine section around the Green Ridge of South Mountain after an orator compared the path to a tapeworm depiction on a product's packaging. Switchbacks were planned on the west slope at Hughs Forge along the E Br Antietam Creek and on the east slope at Stevens' 1822 Maria Furnace along Toms Creek, with 3 east slope tunnels through spurs of Jacks Mountain.
In 1836, Herman Haupt had surveyed the "road from Gettysburg across South Mountain to the Potomac" and in 1838, the rail "bed" was "graded for a number of miles, never got further than Monterey", and included the following :
After Thaddeus Stevens lost his position on the Canal Commission, the commonwealth ended the railroad's financing and work was suspended in 1838, and an 1839 survey was ordered of the planned line.
The Tapeworm Railroad right-of-way was later used by the Susquehanna, Gettysburg and Potomac Railway and its successor, the Baltimore and Harrisburg Railway to build a line from Gettysburg west to Highfield, Maryland. These companies were acquired by the Western Maryland Railway in 1917.
