Can't be all that hard though. The northern line got them in 1980s.

When you've got signalling equipment dating back to the 1920's operating on
the SSL, plugging in new kit to interface with that isn't likely to be a
simple job - and anyhow, any such efforts are better expended on the
wholesale signalling upgrade.

There was old equipment on the northern and piccadilly too but they managed
to get them working on there so where theres a will...

As I said I'm not expert, but my understanding is that the signalling
equipment was/is newer on those lines than on the SSL.

Where there's a will *and a budget* there's a way - generally it's difficult
to do such things without any funding.

The point is, the Northern and the Piccadilly weren't scheduled for
major signalling upgrades until long after the SSL upgrade was
supposed to take place.

Two scenarios:
a) you buy a dilapidated house, move in, then start applying for
planning permission, organising builders, etc, to have it knocked down
and completely rebuilt. You're planning to start building work in six
months or so, and get the new house done within 18 months.

b) you buy a dilapidated house, move in, and although you'd like to
have it knocked down and rebuilt at some point, you won't be able to
afford to do so for at least five years.

In case a, you're probably not going to install a new kitchen or
bathroom, have the house rewired, or do anything other than basic
repairs that make it just about habitable. In case b, you'll probably
make some changes, because although they're temporary and you don't
want to spend too much on them, they'll make the next five years much
more bearable.

Of course, if you're aiming for scenario A, but your builder goes
bankrupt and you end up spending several years suing each other, then
you'll probably regret not installing the new shower and cooker that
you'd have put in if you knew you were going to be stuck there for
years. But that's the benefit, and the problem, of hindsight...

Yes, but the northern line had electronic train indicators installed almost
25 years ago! Any signalling upgrdes to SSL weren't even a twinkle in
someones eye then so theres no reason not to have done them too.

I would respectfully suggest that you simply don't appreciate how antiquated
some of the signalling is on the SSL network. I'm not sure this discussion
is really going to move beyond that point though.

So you're suggesting theres no sort of timetable machine of any vintage
controlling the signalling on the H&C? Its all just reactive signalling -
train goes past , signal goes red, end of?
