Harpers Ferry tunnel

The Harpers Ferry tunnel is a location in the Mire region of Appalachia. It is a historic train tunnel near the town of Harpers Ferry that was once the site of an underground pipeline project by the Bysshe Company.

Background
In 2104, the Vault Dweller had to pass large sets of strangler vines blocking passages in Bysshe Company's secret, underground natural gas pipeline facility in Harpers Ferry tunnel. To achieve this, the Vault Dweller would utilize a strong herbicide developed by the Bysshe employees prior to weaken the vines enough to allow them to be cut or shot down.
