The far more logical routes are via Oxford Circus to the Central
Line or via Paddington to the Circle / District lines and then
either to Notting Hill Gate and then the Central Line or else a
District or Circle to Earls Court or Gloucester Road to change to
a District to Ealing Broadway.

Er, the destination was actually Turnham Green. So the Central Line will
only work if you implement the 1922 (not 1928 as I wrote earlier )
extension proposal (Shepherd's Bush to Gunnersbury).

Ooops - well that's me looking like an idiot. Still nothing stunningly
new there then.

Earls Court is a level interchange while Gloucester Road
is awful M-F but a cross platform at weekends due to the platform
usage at Gloucester Road. Can your system cope with those
subtleties?

It used to be the case that westbound Districts used Platform 2 at
weekends, but I don't think that happens any more. They all used
Platform 1 in WTT129 (29 Sep 2002), the most recent that I have.

Double oops.

The most basic rule for calculating journey times is 2 minutes
average time between stations and 5 minutes for a non zone 1
interchange and 10 minutes for a Zone 1 interchange. This assumes
normal mobility and a reasonable walking speed. There are obvious
exceptions to this rule but it works pretty well IME.

There are off peak journey times shown on timetables for each tube
line on the Journey Planner so you can see exactly how long a trip
should take. Peak trips obviously take substantially longer due to
more trains running and extra congestion.

Obviously? More trains running ought to make journeys quicker. But it
would need better signalling and/or ATO and/or operating efficiency to
prevent the increased dwell times that make journey times longer. London
is still catching up with Paris in this respect, 20+ years later.

I take the point but we all know that LU is not at that level of
sophistication yet. Lines like the sub surface ones tend to crawl in
the rush hours as there are so many flat junctions and without
absolutely on time running you will get tail backs.

The same is true for the Northern and Piccadilly Lines where Camden,
Kennington, Arnos Grove and Acton Town are all pinch points. If
everything is OK then the Vic runs fine and the Jubilee seems to have
improved. However there is still the issue of station congestion which
will increase - sometimes substantially - the time for interchange
between lines.
