Yesterday, I visited the recently renovated and opened Lee Hall Depot in Newport News, VA. Built in 1881 by the C&O when its line was extended from Richmond to provide a deep water port for the export of coal, the station was one of several along the right of way. Very nice restoration with period fixtures and artifacts. (Free admission with reserved tickets.)
One of the main movers in the project was also a fan of 3-rail trains and some were on display.
