RR or MRR things to see in the Shenandoah Valley of VA

My Wife and I will be traveling to Strasburg, and Staunton VA next week. I wanted to go see the Pochahontas Coal mine but it is an additional 4.5 hours away according to Yahoo,maps. So what would be a must see RR wise and hobby shop wise in that area. I already know about the great old station in Staunton. Thanks, Dave
