This is very roughly based on the coal facility at Vance Junction on the Rio Grande
Southern Railroad. I had a partial set of plans, a partial photo of the real item,
and a partial photo of a HO scale model of the item. No two looked completely alike so
this is an amalgamation of the three. Neither picture showed the top so is based on
the partial plan which seems to indicate coal was shoveled in from low side gons. This
is animated and interactive on all 8 chutes with smoke and sound. Since they are close
together trigger radius is small (1 meter).
