All I'm trying to do is to understand your reasoning. You say that the
HSE wouldn't allow a new situation where tube and mainline trains share
the same track, and cite the vulnerability of tube trains in a crash.
But that's not the logic that was followed after the Ladbroke Grove
crash where the leading car of the 165 was destroyed by impact with the
HST power car. The solution was not to segregate DMUs and HSTs but to
improve safety systems to reduce the risk of a collision. It seems to
me that the same principle would apply to any future tube/mainline track
sharing.

Well I would agree with you , but whoever said the HSE were logical?
As far as
I'm concerned they're nothing more than a bunch of bed wetters who'd
like
nothing better than to cover everyone in cotton wool and lock us away
in a padded room for our own safety.

All I know from reading things in print and online is that the HSE
wouldn't
allow any new situations where sharing of track between tube size and
mainline
size trains occurs but they do allow the current status quo to
continue. IIRC
they even have a beef about the met and piccadilly trains sharing
tracks.
