ORANGE, Va. (AP) — A new tour guide aims to connect railroad enthusiasts with Orange County's rail history and today's railroad presence in the county. The "Tracks Through Time" tour guide is scheduled to be launched on Tuesday at the Orange County Visitor Center in the restored Orange County Train Depot. Orange County tourism manager Leigh Mawyer says in a news release that the guide has hundreds of notes on 27 sites. The guide also includes a map and GPS waypoint references to each site.
