Lionel pellets or Megasteam fluid?
that looks alot like the abandoned warehouse it used to be parked under. It fell down years ago.
I didn't know about the compressed air test, but it makes sense considering there is no steam at the cylinder cocks or packing. Also don't hear any steam powered appliances running. Still a shame to see such a large beast go by the wayside, but I suspect at this point it may be doomed to the scrap pile. A remnant of a bygone era that simply doesn't translate well into a new purpose like pulling excursion trains. The price is now actually somewhat reasonable given the size of the equipment, but being on dead rail in McKees Rocks, near a class one that isn't particularly friendly to steam locomotives, isn't doing it any favors.
