@wmeehan @ndhapple I think the real dark horse candidates for messiness are:
- Stillwell (low capacity/holdouts)
- Nostrand (peak service levels here are lower than you think)
- Forest Hills (usually congests back to ~63rd drive at peak; all day 20tph into here will need some serious ops reform)
- 145/BPB (both north ends of the B are single pocket terminals, one of which backs onto a major junction. Not a recipe for fun)
