Where trains once ran, but no longer do. Abandoned rails, bridges, empty tunnels, rights-of-way, rolling stock. Cold locomotives, quiet stations. Rails to trails. Rail-bikes.

Live and active tourist and regional shortlines are not ghosts. Archive photos are not ghosts. Plenty of other groups where those photos can be posted.
