Now that I think of it, you could take a ride to Harpers Ferry Wva. Nice area, lots of history. CSX regularly runs through town over bridges and through tunnel. Beautifully restored B&O depot.
Just outside of town at a guys house is the Joy Line Miniature Railroad and Toy Train Museum. He has a loop of 16" gauge track in his front yard with classic "park trains" from area amusement and city parks he has restored. In his barn is a large standard gauge layout and toy train collection. He is usually open weekends Apri - October. Lots of fun, just a mile or two outside of downtown HF.
