The Enginehouse pictures are on pg 1 of this Thread. I'd say the TT predated the Enginehouse by the first heavy snowfall.
Keith, I'm glad I'm not the only one to get N/S/E/W turned around.

I'll look in my files for the s.g. trackage map. There was little changed apart from adding the Wye leg and additional tracks up in the Mill area: I doubt there even was a spur there before the mid 1910's.
