I recently toured this line. The stations at Franklin City, Girdletree, and Snow Hill are extant. There are also a couple of vintage RR crossing signs in girdletree where the line used to be. The station has been moved a few blocks away. If you make a trip out to trace this line there is a great restaurant in Greenbackville (the only one) run by a gourmet chef that you need to eat at.
The station building at Franklin City has seen better days and looks like it is going to fall into the bay eventually.
