There was certainly a comment a few years ago that crossrail would be a lot
more expensive if it didnt breach the tunnels . *Presumably they are going
ahead with the version that does.
Why does it need to breach the Post Office Railway? They follow more
or less the same route, and the Post Office Railway keeps mainly to
the north of Oxford Street - as that's where the postal offices are/
were - while Crossrail mainly keeps to the south (think of where the
stations are).

Even when Crossrail deviates at farringdon, the Post Office Railway
deviates further to the north to reach mount pleasant.
