There is a plan to replace to rearrange the subsurface lines so that:
- the Metropolitan is extended to Barking instead of the Hammersmith
and City
- the Hammersmith and City and Circle are replace by a new line running
from Hammersmith, via Paddington, Kings Cross, Tower Hill, Victoria and
Paddington to Edgware Road, where it would terminate/reverse.

Before questioning The Dave, check your scripture:

http://www.alwaystouchout.com/project/39

Which sayeth:

"2011 - New service pattern

"The peak hour service is currently 28tph on most of the subsurface
network in Zone 1 and is due to be increased to 30tph, to be achieved by
restructuring the service - in particular the Circle line.

"Metropolitan trains would run through from Liverpool Street to Barking,
and the Hammersmith & City service would run partially to Aldgate, and
partially all the way around the Circle terminating at Edgware Road - i.e.
Hammersmith - Edgware Road - Aldgate - Victoria - Edgware Road and
reverse.

"This is meant to give a period of recovery time which the Circle line
currently lacks. Detailed information is available at Tubeprune's site and
District Dave's site.

"Works will be undertaken on the Hammersmith & City line station at
Paddington to relieve overcrowding."

Note that because of the new shape of the H&C (which, AIUI, entirely
replaces the current Circle service), at Paddington, no trains on the
Circle/District platform will go beyond Edgware Road, so should that way
lie your destination, your only option is to go to the H&C platform, which
is easier than the choice you face at present.

Also, the frequency of trains from the H&C platforms to Liverpool
Street will be increased (doubled?). If that didn't happen (i.e. the
only change was that trains from the Circle platforms terminated at
Edgware Road) then it wouldn't be much of an improvement - although,
as you say, the choice would be easier. ;-)

Having said that, I'd hazard a guess that the Hammersmith-Aldgate
service won't run off-peak (otherwise why send the Met to Barking?),
which would mean this increase would only be at peak times.

Random PS - why didn't the Bakerloo get called the Regent Line, since it
runs via Regent's Park and Regent Street? That would be a much better
name. 'Bakerloo' makes me cringe every time i hear it.

Well, no. At least, "Rails Through the Clay" (2nd edition) says otherwise:

# The clumsy statutory titles of the three lines were, [of] course,
# too much for the man in the street. A writer in the Evening News
# (G.H.F. Nichols, or 'Quex') coined the tag Bakerloo for the Baker
# Street & Waterloo, a name used by the paper from 7th March 1906¹
# and quickly accepted by the company, which adopted it officially
# from July. This move staggered the prim anti-American editor of
# The Railway Magazine: 'for a railway itself to adopt its gutter
# title, is not what we expect from a railway company. English
# railway officers have more dignity than to act in this [manner].'
# Mr Nokes was spared further nicknames: the other two lines simply
# became known as the Piccadilly² Tube and the Hampstead³ Tube,
# titles which were officially promulgated and stuck well enough.
# A competition was held by the Evening News to find a short title
# for the Piccadilly tube, but none of the rather awkward suggestions
# proved acceptable to the company.

[] indicates places where I have corrected typos in the passage.

¹ 3 days before the line opened. The Piccadilly's opening followed in
December of the same year, so the competition was presumably held in
the intervening months; the Hampstead opened in June of 1907.

² Great Northern, Piccadilly & Brompton Railway.

³ Charing Cross, Euston & Hampstead Railway. The name Northern Line
was first used in 1937.

It had been called the Morden-Edgware line by then, indicating how much
it had expanded (also incorporating the City adn South London) since 1907

I refer you to your previous post:

"Metropolitan trains would run through from Liverpool Street to

Post by Tom Anderson

Perhaps it was a bit of a leap, but I was thinking that if the Teacup
service is 6tph off-peak, there might not be a need for additional
trains from Hammersmith as the frequency on that branch would be high
enough anyway. If the trains from Hammersmith to Barking don't run
off-peak, there would be no through service between the East End and
the northern Circle at those times - hence the Met/H&C Aldgate/Barking
swap.


Thinking about it a bit more, unless I'm missing something, the
suggested service pattern seems to be hopelessly inefficient in terms
of movements across Praed Street Junction.

Let's assume the Wimbleware frequency is 6tph (as at present), the
Teacup runs at 7tph peak / 6tph off-peak (same as the current
Circle/H&C frequency), and suppose for now the Hammersmith-Aldgate
frequency is 0tph. This results in exactly the same number of
movements across Praed St Jn as at present. The frequency of trains
from Edgware Road to each of Hammersmith, Wimbledon, and Gloucester
Road (and beyond) stays the same, but the frequency of trains through
to Baker Street and King's Cross is halved. That would, however, allow
more trains to run through from the Met to the City (perhaps that's
the whole idea?).

Now add in say 6tph Hammersmith-Aldgate. This restores the frequency
on all routes to present levels, except it doubles the frequency on
the Hammersmith branch. This is, of course, good. However, Praed St Jn
is now hopelessly congested.

What am I missing here?

Two possibilities:
- Hammermsith to Aldgate is a transitional stage before the T-Cup is
introduced
- Hammermsith to Aldgate will be an extension of the T-Cup service (ie
trains will do a lap of the circle before terminating)

Just done a quick calculation. I make the distances:

54.69km Epping - West Ruislip
56.76km Amersham - Barking

So the Met line would end up longer (and longer still if trains ran
through to Chesham).

The off peak service pattern is:
Aldgate - Uxbridge (All Stations)
Baker Street - Watford (All Stations)
Baker Street - Amersham (Fast - Wembley Park to Harrow and Harrow to
Moor Park)

In the peak there are all sorts of fast, stopping and semi-fast
services running the whole or part of the line, as well as 2 with flow
peak Chesham - Aldgate Fast services, there are also some other early
morning and late night Chesham 8 car services. Of course the Controller
often amends the stopping patterns if gaps arise in the service or
divert trains to cover other branches gaps.

Don't forget that the entire Sub-Surface Railway will be very very
different in 10-15 years tim to what it currently is, including the
District running to Uxbridge instead of the Piccadilly

Presumably this will allow the future signalling upgrade on the Piccadilly

Uxbridge?

A higher frequency on the rest of the Piccadilly I guess, because the
line will be shorter in the end, while there would be enough
sub-surface stock to extend the District back to Uxbridge.
This would be a very unattractive service for everyone from North
Ealing to Uxbridge though, since virtually all of those people will
want to get on the express. It doesn't make much sense to make the
longer line the slowest one here, and the shorter (Ealing Broadway)
line the express.

Surely Ealing Broadway would remain District too... the point of the plan is

Broadway would defeat the point of ceasing to serve Uxbridge.

Anyway, didn't they rebuild a Sudbury station or two to have platforms level

You need less trains for an Ealing Broadway picc. branch than an

[chunky munky]

There are a number of reasons why the District will end up at Uxbridge
eventually (with the Picc going to Ealing Bdway?).
- The Piccadilly will benefit from the additional rolling stock, when
Terminal 5 opens. There is no new stock for many years yet.
- The platform to train heights will be "level/ step free" between
Rayners Lane and Uxbridge. As set out in the PPP Contract
- The ATO systems for Tube Lines and Metronet will be different, though
thinking about it now must be compatible for the North Ealing to Acton
Town section, unless as some have said the District runs to Ealing
Broadway.

The SSR will be different in that it will have new trains, new
signalling systems with 12 control/signalling locations being replaced
by one Command & Control centre, step free access to the trains,
changes to the lines.

at Ealing Common or between Rayners Lane and Uxbridge.

The southern Circle couldn't handle a fifth western destination - the
frequency on each is bad enough with 4. Perhaps Ealing Broadway could
be served instead by an Ealing Broadway - High Street Kensington
service. Or the District service could even become a bit like the Met,
with a proportion of trains from all branches terminating at HSK (cf
Baker Street) instead of running onto the Circle.

Here's an alternative idea, though it's a bit off the wall. By this
time, the District will run under ATO. The driver won't actually drive
the train (under normal circumstances), but will just press "go" and
the train will drive itself to the next station. This would mean that,
just like on the DLR, the driver wouldn't need to be sitting at the
front end of the train - he could reside in an area with door controls
(like the guard's areas on pre-DOO Tube stock), or roam the train
(like on the DLR).

Build a west-to-north curve so that trains can run through from Ealing
Broadway to North Ealing. District trains to Uxbridge would run
Central London - Ealing Common - Ealing Broadway (reverse) - North
Ealing - Uxbridge. A reversal en route wouldn't be a problem as
there'd be no need for the driver to change ends.

Result: Ealing Broadway and Uxbridge branches both served; new local
service to Ealing Broadway from the north; faster journey for London
commuters (by changing to Crossrail at Ealing Broadway).

This is a rumour that surfaces from time to time (usually when one of
those Green railways types takes a wrong stick at Hanger Lane) which has
no factual substance.

The fact that some of the platforms down the Rayners Branch have been
recently rebuilt to tube gauge stock suggests that TPTB have no plans to
do this.

What about Hammersmith to Barking? There used to be a Circle Line
train, no. 201, that started from Hammersmith (H&C) at about 04:49, went
20 times round the circle and finished up at Barking at 00:58. Total
distance about 440 km (273 miles) in continuous public service with no
reversing.

Can someone with the current WTTs check whether it still runs?

[chunky munky]

The last Barking Train (ex Edgware Road) is indeed an Outer Rail
Circle.

Haven't got a Timetable with me at the minute but I think 4 or 5
Circles stable at Barking in the Evening and there are 3 Start-Ups.
These run advertised as Circles until their last arrival at either Glos
Rd or Edg Rd on the Outer Rail or Glos Rd/ Tower Hill on the Inner
Rail.
It is common for the Train to display the correct destination and the
Dot Matrix to have the wrong destination. This is either because the
DMI can' t show the data or the signalling system can't input it (like
Edgware Road to Glos Rd Inner Rail)

54.69km Epping - West Ruislip
56.76km Amersham - Barking
So the Met line would end up longer (and longer still if trains ran
through to Chesham).

This should throw up some interesting things

- on the linear map of the Hammersmith and City line
Paddington and Edgware Road appear twice

- Two different ways to go from Paddington to Edgware Road via
Hammersmith and City - from totally seperate platforms

- Idea of going from Embankment to Monument via Westbound Hammersmith &
City - just weird

- You could walk between Royal Oak and Bayswater in ten minutes, or
take tube - over an hour Id guess

- Three lines to choose from between Gloucester Road and Hammersmith,
two stops on Piccadilly, three on the district, or 31 on the
Hammersmith and City

- If they build the tunnel connecting Euston Sq and Euston three ways
to get from Euston to Kings Cross - Eastbound H&C Northbound Victoria

Not to mention that all the way from Gloucester Road to Tower Hill,
there are trains to Hammersmith in both directions, and the one
advertised as going there is most likely the slower one.

Similarly, the fastest way to Hammersmith from Bayswater, Notting Hill
Gate, and High Street Kensington is to take a train towards Hammersmith
only as far as Gloucester Road and change to a District/Piccadilly train
in the opposite direction.

In another thread, Dave Arquanti commented that "The new service pattern
on the Circle and H&C lines will make using Paddington much easier"
Could anyone expand on this please? A brief google has returned nothing.

Yeah what does Dave mean?

http://www.alwaystouchout.com/project/39
"2011 - New service pattern
"The peak hour service is currently 28tph on most of the subsurface
network in Zone 1 and is due to be increased to 30tph, to be achieved by
restructuring the service - in particular the Circle line.
"Metropolitan trains would run through from Liverpool Street to Barking,
and the Hammersmith & City service would run partially to Aldgate, and
partially all the way around the Circle terminating at Edgware Road -
i.e. Hammersmith - Edgware Road - Aldgate - Victoria - Edgware Road and
reverse.
"This is meant to give a period of recovery time which the Circle line
currently lacks. Detailed information is available at Tubeprune's site
and District Dave's site.
"Works will be undertaken on the Hammersmith & City line station at
Paddington to relieve overcrowding."
Note that because of the new shape of the H&C (which, AIUI, entirely
replaces the current Circle service), at Paddington, no trains on the
Circle/District platform will go beyond Edgware Road, so should that way
lie your destination, your only option is to go to the H&C platform,
which is easier than the choice you face at present.
tom

To add some clarification on service frequencies to this, I believe the
idea is to double the frequency of Hammersmith departures. The current
frequency on each of the H&C, Circle and Wimbleware services is 8tph
(every 7.5 mins). The "teacup" plan would (theoretically) involve 16tph
departing from Hammersmith, resulting in a doubling of service on the
Hammersmith-Paddington section, giving a much improved service to the
White City shopping centre which will push up demand on the line (via
the new station at Wood Lane).

It will also provide big benefits at Paddington, where interchange
passengers from National Rail can head to the Bishop's Bridge (current
H&C) station for 16tph (direct) to the east, an improvement over the
current situation with direct trains split equally between those
platforms and the Praed Street (Circle line) platforms. Additionally,
the extensive development in the Paddington Basin is closer to the
Bishop's Bridge platforms and will benefit from a better service to them.

However, the obvious problem is that 16 circular services do not fit
along either the southern Circle or into the terminating platforms at
Edgware Road - so it seems likely that 8tph will halt at Aldgate and
reverse, with the other 8tph continuing round to Edgware Road via
Victoria and back, just as the current Circle service.

Unfortunately, it means a bit of a raw deal for journeys on the western
part of the Circle, as there will be no frequency increase and a break
in journeys passing through Edgware Road - but hopefully with the prize
of improved reliability.

Other people may know more than I do, so please step in to correct if
necessary!

[chunky munky]

Must be the plan for the Hammersmith & Circle line, which has to wait
for the new S7 stock to arrive, as there isn't enogh C Stocks about.
The current idea is Hammersmith (Met) -> Edgware Road -> Aldgate ->
Gloucester Road -> then either up to Edgware Road or down to Wimbledon.
The Met will then be diverted from Liverpool Street to Barking.

No idea about frequencies or if the service will run past Edgware Road
as a loop?

- current Aldgate junction is too crowded.

Yes, it's additional change for passengers, but it will result in

No - witness any line at Oxford Circus, where a mob get off a train to
be replaced by a mob getting on. Imagine if the Central line didn't go
west of Marble Arch - the trains would get emptier and emptier as they
approached Marble Arch from the east, whereas there is currently a

reversing some Districts at Tower Hill would come into play. The only case
where you need to preserve the full District service beyond Tower Hill is
if there's much more demand for trips from the eastern end of the

In the daytime off-peak, it's basically the Ealing Broadway trains that
reverse at Tower Hill, while the Richmonds and Wimbledons go to
Upminster. So the answer is about a third, or about a quarter of all
eastbound traffic if you include the Circle. In the peaks, it may well
be different.

OK, here's some data to chew on - Figure 4C.2 of the Mayor's Transport
Strategy is a particularly useful diagram showing Underground crowding
levels for 2001, with the following figure showing predictions for 2011
- so imagine something between the two. The width of the lines is the
magnitude of demand, and the colour is the crowding level. (You need
good zoom or good eyesight to check that you're looking at the correct
direction of travel.)

2001 shows a higher and crowded passenger flow from Aldgate East to
Tower Hill, and a much lower (but still crowded) flow from Aldgate East
to Liverpool Street.

2011 prediction (albeit this is meant to be without the Transport
Strategy) shows crowding again to Tower Hill and a still low but "very
crowded" service (i.e. crammed) from Aldgate East to Liverpool Street.

Demand from the western branches into Victoria and the City is very high
and very overcrowded, compared to that from the east.

The difference in the magnitude of demand in the east suggests that the
Tower Hill service should be much more frequent than the Liverpool
Street service (perhaps doubly so), which I think is about the shape of
things at the moment.

It's also worth bearing in mind that a reduced-frequency
east-District/southern-Circle service may push people onto the
very-high-frequency Central line at Mile End to get to Bank or St Paul's
(whereas they would have stayed on to Monument, Cannon St or Mansion
House), and the Central line already suffers worse overcrowding than
either the District or the H&C in this area.

To me this suggests that the District frequency to/from the east should
be maintained, as the balance is quite delicate.

Indeed. However, whilst the downside is that they're complicated, the
upside is that they end up matching demand more closely than simpler
Underground all-or-nothing service patterns.

They do also relieve some stress from the Underground by offering a
choice of termini...

[j***@gmail.com]

An improved service from the north side of the circle down to Barking
would have a great effect on the central, plenty of people (myself
included) could take either into the city, but opt for the central
(which involves changing) on the basis of reliability, frequency and
speed. With a decent frequency and spanking new ACed up S Stock I know
I'd prefer that to standing with my head at a 45 degree angle squashed
up against the doors in 40 degrees on the central.

T-cup seems to make a lot of sence, the paddington stations
improvements would also be well recieved, I do Paddington - Bow Road a
fair bit, and will normally take bakerloo, central and district rather
than gamble on the cooperation of the H&C. Thought the unified aldgate
interchange is interesting (I do this on foot a fair bit, one of the
great irritations of oyster is that it would not let me do this
without paying for the privalage of walking), If that could be done it
would be a very usefull addition for people living/working on the
district.
