Crossovers behind the station, unless their geometry is vastly different to those ahead of the station, won't help reduce headways on the line. They certainly won't at Finch, in any of its potential configurations.Yes, the geometry at Finch, with it's longer crossovers since it has a center platform, mean a longer headway, a side platform terminal station should have the crossovers beyond the station
Double crossovers as a general rule have a reasonably high minimum theoretical headway because no matter what you are going to have a number of different situations during the cycle where one train will tie up the entirety of the interlocking plant. There are other methods of turning trains that allow for far lower headways.
