Having ‘chopped up’ part of the original layout, removing the coke ovens and the rock behind them I was left with a small stub of On18 track about 9 inches above the lower level. I printed out a quick and dirty model of an ore bin for this location with the idea that ore would be delivered by the On18 line to the ore bin where it would be picked up at the lower level by the On30 line.
Note: One thing I would change given the chance would be to have the layout in sections that could be removed to be worked on. The On18 line is extremely hard to get to. If I could sit the section on saw horses I could add something like .. oh . I donno .. a siding for example. *sigh*
