According to some sources, they can't do the
"next train" indicators that we have, as it's "too
complex", which I think is b*ll*cks, but there you are.....

Well, LUL can't do the next train indicators either,
at least they can't do them properly!

True, but at least they give you some idea!

What I meant was that although they are very useful on the Victoria Line and
certain other lines, there are stations on the Circle Line where the nice
multiline LED displays only tell you about one train[1], and only when it is
practically in the station anyway. The Piccadilly Line displays are great at
telling you about the next three trains to Heathrow but neglecting to give
any clues about the next train to Rayners. It is almost as if the system was
bought off the shelf, having been originally designed for a network with
simpler lines (such as Tokyo or Paris Metro).

[1] That's one LU train, not one ONE train.

You know I never even considered that it would be more useful to show
the next trains to Heathrow and Rayners Lane rather than just the next
three trains whereever they go. I suspect that it wouldn't cause much
problem on the Piccadilly technically... but I think they prefer people
to just get on the first train to Acton anyway if there's no Rayners in
the next three, to ease possible overcrowding.

After all, in the winter when you're waiting in a warm tunnel, if you
knew the next Rayners train was in ten minutes and that it was the fifth
train, would you still get the first train to Acton Town and change...?

Seems to work pretty well on the Northern Line, though, than which you
can't get much more complicated. I'm learning rather more about its
vagaries than I ever wished to know, at the moment..... the Jubilee line
seems far simpler.

You've obviously missed the best ones:

"This train terminates at NEASDEN" - NEASDEN said with in a very stern,
angry tone after the almost cheery "this train terminates".

"This train terminates at FINCHLEY Road" - FINCHLEY is said about five
octaves higher than the rest of the announcement. This one's a real
classic. The first time I was on a train terminating there you could
see everyone laughing every time she said it.

Yes, I haven't heard those yet. Only Stanmore, which is pretty normal,
and "Willesden Green" in the isn't-that-interesting tone of voice a
friend of mine uses to speak to small children in!

While I acknowledge the points that you have made about refining the
information provision the main point is that the dot matrix indicators
(DMIs) were a simple upgrade off the back of existing signalling
systems. In the case of the Circle the signalling system and design is
not sophisticated enough to look back far enough to correctly determine
the sequence of trains. There is also the issue of trains terminating /
departing at key junctions (edgware rd, aldgate) that add to the
complication as to what will be e.g the next s/b train at Paddington on
the Circle / District line.

The Jubilee Line and Central Lines are better because there is a much
more up to date control system which can better understand where the
trains are relative to the timetable and can therefore provide a better
prediction of arrival times and destinations to both the controller and
to the DMIs. Almost every other LUL line is decades behind modern day
practice - new displays will be provided at all stations and when Line
Upgrades come into operation there should be the level of sophistication
of information that deals with the network's apparent complications. I
look forward to that day.

The westbound District and H&C lines at West Ham are a classic example.
You can see the train in the distance either before or at the same time
as being able to see it on the indicators. That said, my generaly
experience of the indicators is that they work well and are a handy
thing to have.
