Interesting stuff on this proposed museum in Niskayuna, NY, which never came about. It was to be a large, modern campus with displays ranging from a submarine to the steeplecab Black Maria locomotive.

And what happened to the railroad equipment?

Both North Shore cars and both pieces of equipment from Ponemah Mills (the historic "Black Maria" locomotive and a small work motor) went to the Connecticut Trolley Museum in the early 1970's. NYC S-motor #100 was somehow involved in the AME for a time, I believe, and it ended up with the Mohawk & Hudson NRHS chapter.
