In the early days of the railroads, some tunnels were lined and the portals faced with wood timbers. Many of these have been abandoned or replaced with concrete, brick or stone, but some are still in use today. All wood pieces are precision cut typical of Campbell Scale Models. Finely detailed instructions help make this another or our outstanding kits.

The "N scale" portals can also be used as dandy mine entrances for our HO enthusiasts.
