Huh? Grade-separating the scissors crossover is hardly a huge leap of

So? That doesn't change the fact that with almost all of the
conflicting movements created by a flat terminal layout removed by
grade-separating the scissors crossover, line capacity can be massively
increased.

If it's so humdrum, why hasn't it been done yet?

The idea may be trivial, but finding the will and the funding to
actually do it most certainly isn't!

Especially considering it would only really be necessary from (year
when new Vic stock is introduced) until (year when Crossrail 2 opens)
- projected at 7 years, though no doubt it will be nearer 20
