Nells; better have a Maine map to understand this. Yes,the "beautiful people" in Belfast have "ridden" themsleves of that grubbly railroad property on their waterfront,an obstacle in their egocentric/elitist minds to making Belfast an example of "yuppiedom".
So trains WON'T run to Belfast. The B&ML has made Unity,roughly at the mid point of the line,for several years now. Trains will run NORTH from Unity to the end of the line at Burnham Jct.,where the B&ML connects with the Guilford Freight Mainline. There is a wye there.
This ride is NOT as scenic as near the coast,and I hope they do well. Unity has the restored station,enlarged,with a visitors center/museum,as well as the engine house etc.
Haven't been "up there" from my home in S. Maine in about 3 years,but there are "a few" derelict cars, bldgs. etc. But these are mostly SOUTH of Unity,at Thorndike,once the site of a huge feedmill,that brought the B&ML its last prosperous freight days,hauling many thousand feed hoppers,for the now defunct chicken industry in Waldo County.
Haven't heard if they will run their Swedish steam engine this summer,or use a 70 ton G.E.
I know they have a website.
Hope this helps.
