A historic train tunnel near the town of Harpers Ferry in West Virginia, prior to the Great War the infrastructure was used to travel east across the mountains. Unbeknownst to the public, it was also the site of an underground pipeline project by the Bysshe Company.
At some point after the war, the tunnel was used by the Blue Ridge Caravan Company to transport goods and people into Appalachia.
In 2104, the Vault Dweller had to pass large sets of strangler vines blocking passages in Bysshe underground natural gas pipeline facility. 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.

- Aries: "Just your run-of-the-mill illegal natural gas pipeline, courtesy of the fine people at the Bysshe Company. A bit before the War, Bysshe offered to maintain this historic train tunnel out of the goodness of their cold, corporate hearts. And, wouldn't you know it, they may have had an ulterior motive."
