So fill us in on how removing a set of points increases operational
flexibility then.


It doesn't.


But the cost of that operational flexiblity is increased disruption
(points fail more often than plain track) and increased cost (points
need more maintenance then plain track).


If they're clipped out of use most of the time they can't fail short of a
rail breaking.


Moreover, when they are needed, the returns in goodwill and
convenience to passengers is enormous. *If one of the two lines is not
available on Monday morning after a weekend possession the ability to
still move at least some passengers to work is great asset.


But you can still do that on whichever service is still running and
you'll get more trains through the area that way than trying to run
two 'special' services over one track with the problems in pathing
over the pointwork at each end.

Well that's the Mile End of the conversation.

What about St Pauls?

Victoria lines.

All the signals have been sellotaped and bagged over, including the
platform repeaters - I used to use the trio cluster of signal
repeaters on the Jubilee concourse at Stratford to know if I should
make a hasty run for the next departure or casually walk to the
opposite platforms and travel on the next train.

In comparison to the Central and Victoria line systems, the Jubilee
ATO drives the train at a very humble and civilised pace, unlike on
the other said lines which have the touch of an elephant and drive the
trains as “fast as possible between stations” (the words of a Central
Line manager who I once spoke with) and brake on a sixpence at the
very last possible moment. From what I experienced today, the ATO
accelerates to line speed then coasts and gradually notches back up
should the speed fall, unlike on the Central line that I notice is
driven by only using acceleration and braking without coasting in a
constant power-brake-power-brake-power state.

I believe that pre-ATO the 1996 stock (and Northern 1995s) were
restricted to 60-70% power - now that ATO is in operation have they
been let off their leashes? It was difficult to notice any significant
acceleration/braking difference.

One last question, I know that on the Central Line that the platform
staff are informed that the train is ready to depart by ***MIND THE
DOORS*** appearing on the dot matrix displays and on the Victoria the
platform repeaters are still used but I couldn’t understand how the
platform staff at Westminster knew when to announce that the train was
ready to depart now that the signals have been obscured?
They have white lights:

at Westminster there is one where they have the lights.
