I have maybe 30 gold (estimated, I forget the exact amount), so I won't have enough to supply the whole thing. However, I will calculate the amount needed.
Also, it'll vary by 32 or 34 rail pieces depending on whether I make the rails go into the ravine observation deck or not. For now, I'll measure from the end point of the station. I'll also include the wall coords of the corners to factor those in.
Edit: Its 109 (technically 108.5 and 108.7, going by what I calculated) gold and 773 or 774 (or 775? again, due to rounding issues) iron. If I include the iron in the warehouse, collective storage, and scattered elsewhere, I probably have enough iron, but I've got 20 gold. Although if I grab some out of public storage and/or supplement with the track pieces in public storage.....
Edit: Nm, on the boosters in storage as theres only one, but I'll use the gold from public storage. Should have enough that way. I'll also borrow a stack of track pieces, just in case.
