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.

I'm sure I've seen some plans which either confirm or deny a breach in
the Farringdon (Mt Pleasant) area. But I can't find them currently.

My understanding was that the main reason it closed was because the
facilities served by many of the "stations" were no longer used.

The Royal Mail changed their whole distribution strategy to out-of-town
depots.
