Er, yes, assuming TfL aren't lying to us.

Lying about what?

There being cross-platform interchange at Edgware Road between all
terminating Teacups and through Eastbound trains.

I know that's been said here but where did TfL claim that?

I don't think TfL did, it isn't in their press release. It may have been one
of the TfL 'spokesmans comments' in a newpaper article, but it quickly
becomes apparent that it can only be one direction for any individual train.

If in practice they always use the same platform for Wimbleware and the
other one for Circle, something could be shown on advance signage, but then
the 'curtailed at HSK' Wimblewares come into play. That hasn't been formally
announced to the public either as far as I can see, even though the
possibility has been floated here, I think as a result of LU insider info...

Wherever else, it was in the MR article back ... whenever. There was
a diagram showing peak and off-peak frequencies which showed off-peak
Wimbles being reduced north of HSK.

We still haven't stood up this as far as was said until this thread

BRAINWAVE.

On this group, we have two long-standing conundra: how to run the circle
line efficiently, and what to do with the recently disused Widened Lines.

Each is, of course, the solution to the other. We have the exclusive use
of the Widened Lines between Farringdon junction and Moorgate. On that
stretch, there are platforms at Barbican. We build two new bits of track,
and a bunch of crossovers:

- a trailing link from the inner Circle to the up Widened as far west as
possible; east of Farringdon, west of Barbican - this would be a trivial
extension of the Cowcross Street sidings

- a facing crossover from the up to the down Widened immediately east of
the above

- a facing crossover from the outer to the inner Circle also immediately
east of the link

- a facing link from the up Widened to the inner Circle west of Moorgate -
probably involving the Met sidings at Moorgate, at their western end

- a trailing crossover from the up Widened to the inner Circle west of the
link, which probably means west of the existing facing crossover (which is
west of the existing trailing crossover)

- a trailing crossover from the down to the up Widened west of the link

You then redesignate (fast/slow is arbitrary here):

- outer Circle - outer Circle fast
- inner Circle - outer Circle slow
- up Widened - inner Circle slow
- down Widened - outer Circle fast

And you have a four-track Circle between Farringdon and Moorgate, with no
flat crossings. Essentially, Barbican looks just like Edgware Road. You
can have trains on the slows sit in the platforms for as long as they need

Currently looks like this (|- denotes the severed tracks at Farringdon):

Barbican Moorgate

### ###
------------------------------+---------+---------
\ /
--+-----------------------------+---+-+-----------
\ ### \ ####
CX St ------+-+-------#
sgds \ #
+-----#
### ####
|------------------------------------------------#
#
|------------------------------------------------#

And would become (tracks not in routine use dashed):

### ###
---+---------------------+---+---------+---------
\ / \ /
---+-+-----------------+- - - -+-+-+-+-----------
\ ### / \ ####
\ +- - -+-+- - - -#

|- - - - -+-+-------------+-+- - - - - - - - - -#
\ / #
|- - - - - - -+---------+- - - - - - - - - - - -#
### ####

The stubs of Widened line at the Farringdon end probably wouldn't be long
enough to be of any use, but the stubs at the Moorgate end would all be
usable in one way or another. You might need a few more links or
crossovers to make full use of them. Whatever you do, they'll involve flat
crossings, though.

Actually, a cheaper version of this plan would just be to rearrange the
Cowcross Street sidings as a short four-track stretch. I'm not sure it's
long enough, but if it is, that would be somewhere to hold trains which
needed holding.

Argumentative and pedantic, oh, yes. Although it's properly called
"correct" -- Huge

A study of Underground history will show a similar situation at Gloucester
Rd and South Kensington dating from the days of District vs Met egos. You
have side platforms @ Barbican. Unless extensively rebuilt as well, you
won't have the outer rail splitting to sharing sides of one island, inner
rail the other. Instead, the outer rail will be split to one side platform
and one side of the central island. If the down widened lines platform space
is still there, the same would appy to the inner rail. So, there'll be a
load of hoofing it up/down stairs involved. Bifurcation is a good idea, but
only with ISLAND platforms.

By changing at High St or Paddington to a Circle train, a same
platform interchange, this meant the only stairs to be negotiated were
at East Putney (since the King's Cross lift was installed). Changing
at Edgware Road far too often involves crossing the footbridge and the
requirement for that is unpredictable. Now it will be mandatory much
of the time. :-((

The claim is that such changes at Edgware Road will always be cross-
platform.

I presume this will be achieved by the following layout:

Plat 1: H&C/Teacup from Paddington to Baker Street
Plat 2: Teacup from Paddington terminate
Plat 3: Wimbleware from Paddington terminate
Plat 4: H&C/Teacup from Baker Street to Paddington

Possibly with platforms 2 and 3 the other way round; but either way,
passengers who wish to go HSK/NHG/Bayswater to Baker Street or beyond
will be able to know which type of terminating train to get for a cross-
platform.

How will they know? Both types will simply be a C Stock train bound
for Edgware Road.
