Also don't know where you're coming from, but MA, NH and VT offer great opportunities to and from Maine...lots of track, lots of scenery, few trains. But lots of fun. Just pick one or two places. Note that Portland is as far north as Whitehall, NY and Rutland, VT, so it you are coming from the south (NYC, etc,) or the west, consider crossing NE on a northerly course or on Route 2 across MA (paralleling the B&M) and drop down to see Hoosac Tunnel, the Mowhawk trail and East Deerfield. The routes are endless, scenic, and full of tracks.
