These posts are sort of in chronological order in how I visited them over the weekend. I did stop at the Gallitzin Tunnels and Horseshoe Curve briefly on the way into town. The Curve was closed and there were no trains going through the tunnel, so I will save those posts for when I saw the bulk of things there. The first thing I visited was the Railroaders Museum.
If you ever find yourself in Altoona, you should make it a point to visit this museum. Especially if you like railroads and their history.
