Updated December 2002This is not an area thickly populated with smaller railroads, but there are a few short lines here. One might note, from their websites, that there seems to be an inverse correlation between the size of the railroad and the elaboration of the website.
One can follow the Maryland Midland most of its length by car. It is extremely easy to chase a train and get lots of great pictures. There are also two stations to be mentioned. In in Union Bridge, there is a little brick and stone gem which houses the Western Maryland Historical Society's museum. At the west end, in Blue Ridge Summit, there is another station, near the Episcopal church, now the public library. It is immediately recognizable as a train station, but be warned that the side of the building away from the road have all been expanded, some more obviously than others.
There used to be excursion service on this line, separate from the railroad itself. It has been discontinued for years.
You can get a quick glimpse of the railroad main offices from the Harbor Tunnel Thruway heading North, if you are riding a bus. When you come out of the tunnel, there is a section of elevated roadway. If the bus is in the rightmost lane and you sit on the right, you will see a building with a large red and white cross on it that says "Canton Railroad". I don't think you can see this in a car, at least not if you are driving.
