Ligonier Valley Rail Road
This map of the Ligonier Valley Rail Road System is a part of an interactive display in a museum in the Ligonier Valley. Below the map is a reader-rail that contains push buttons that illuminate the different rail road lines on the map. Each stop along the track is a part of a select group of led colored lights that represent the different lines.
