The West Virginia Railroad Museum sits beside the old rail corridor in downtown Elkins, where the town's identity still makes the most sense. It is a small museum, but the subject is exactly right: timber, coal, mountain grades, and the rail lines that made this part of West Virginia reachable.
Go for context before taking one of the excursion trains or driving into the national forest. The museum helps explain why a remote valley town ended up with substantial brick buildings, a depot district, and a stronger cultural life than its size suggests.
