See the big brown 6x6 (or maybe 8x8, I forget…) post between the sidings? The ore bin/tipple/loader structure will need to cover the lower part of this. The mine cars will come out of the mine (at the extreme other end of the sidings) and run down a track between the two sidings to a dump pit that feeds the bucket loader/elevator/conveyor that fills the bin. This is both functional for the “operations plan” of the railroad, but also serves to hide one of a few beams that need to be taken out of the forground of any picture taken!
