There's also a train from Jim Thorpe to Pittston (near Scranton), at least for the spring and summer.

Edit: I actually looked into this a bit more. The train ride is more "something you do" more than something you take. It's $50 round trip and only runs once per day, and is designed to be taken from Pittston. You have to buy tickets two weeks in advance. Definitely more of a private touristy thing. And it takes over 2 hours. You can do it by car in 1.
