I was at South Station once, early for my bus to Hyannis, and one of these was on a track waiting to be hooked up. I love trains and was giving it a good hard look. The people on the car saw me peering in the windows and they invited me on to see it! They were sitting around drinking coffee (it was about 9;30 in the morning) -- wish I'd asked more questions but they said a rich friend of theirs owned and invited them to use it. Pretty sweet.
