Below is the module through the Harper's Ferry Tunnel.
The Weaverton module attaches to the bottom of this corner piece and the
Harper's Ferry module attaches on the right. This part of the layout is short and sweet.
It will be in a corner. The tunnel at Harper's Ferry is unique in
that it is one of the few tunnels to have a switch in it. The tunnel
also exits, heading west onto the huge Harper's Ferry bridges. The
first water way you cross heading west is the Chesepeake & Ohio canal.
The C&O canal competed directly with the B&O line along this route.
The C&O at the time was not a railroad, but a canal company.
