I wonder if they plan to do a mock up anywhere in town.

Do we know why the initial TfL Rail sets for the Liverpool Street to
Shenfield service will only be seven-car? Are there some current platform
length restrictions?

As a follow up to my other post I have subsequently found this on the
web.

"2.4.4 Following the introduction of Crossrail services, the number of
platforms at London Liverpool Street station will reduce from 18 to
17. This is to enable platforms 16 and 17 to be lengthened to
accommodate Crossrail trains; platform 18 will be taken out of
commission."


Maybe I'm being really thick, but I see no reason why the trains running
through Liverpool Street deep have to fit in Liverpool Street surface.
Certainly not if they have to lose a platform to do it.

The new trains will be running into Liverpool St surface platforms before
the tunnel opens, hence the need for the initial batch to be shorter to
fit.

Even after the tunnel opens, some Crossrail trains will serve the surface
platforms, hence the need to lengthen (some of) the surface platforms. But
fewer surface platforms will be needed when most of the Shenfield trains
will be using the tunnel.

Certainly not if they have to lose a platform to do it.

The service level to be provided on the Shenfield line is such that
not all peak trains can run via the tunnel. Therefore some have to
run into the surface platforms. It's as simple as that. To allow the
9 car Class 345s to run into the local platforms on the east side of
LST requires the platform modifications.


I didn't make myself clear. I meant that I see no reason why the trains
terminating at Liverpool Street have to be as long as the trains going
through to Paddington. Certainly not if they have to lose a platform to
do it. How long are these trains and platforms now? Why would the
introduction of Crossrail bring about an increase in the number of
people using Liverpool Street, because I would expect a decrease.

Because over time the cost of not having a uniform fleet (spare sets,
scheduling problems for the normal timetable, flexibility when something
goes wrong ...) is probably greater than the cost of fiddling with
the end of one platform (2 faces). That's all its about. There _will_
be fewer passengers (and fewer trains) at Liverpool Street ("surface"),
so there's no reason not to lose one platform that is just long enough
for an 8-car 315.

No, the existing Shenfield trains use 16,17,18. When Crossrail opens
they will go through the centre (i.e. the new Liverpool Street Crossrail
platforms) except for some in the peak that will go into the existing

Yes, so a platform has been lost. And this is when TfL will at some point
want to increase the frequency of the Overground running to LS.

The Overground doesn't use that side (the old Electric Lines) of Liverpool
St, platforms 11-18. It uses some of the lowest numbered platforms (1-4?)
though it shares with AGA on them.

They don't use that side of the station, though. Is it even accessible from

I think he was suggesting that the tracks into the platforms all be
budged over one, rather than that trains from the westernmost track use
the easternmost platform. I have no idea how easy it would be to do that.

P1-7 - some peak LOROL services get as far across as Platform 7. As
you say the station is shared with AGA who run trains out of platforms
1-15 in totality. TfL Rail have P16-18 routinely but can run out of
other platforms if required.

I think 9 & 10 are for Norwich services with AGA services on 11-15 separate
from those on 1-8.

As I am sure you know the services are "grouped" into batches of
platforms to avoid excessive crossing of tracks in the station throat
at busy times.

Indeed. Which means that AGA services are subdivided into WA & mainline
groups.

No. All are long enough except 16,17,18. In terms of track layout

and I have seen all of 8-12 myself over the years.

That does imply that there's some period where there will be only 2

with 9 cars by that point? Presumably there will be a period when 9 cars
will go through the tunnel, but all surface services will still be 7?

The existing trains are two 4 car class 315 units running in mulitple.
Therefore 8 cars. The loadings are so bad people can't board trains and
TfL Rail has recently starting banning entry to llford station with
people forced to queue outside due to platform overcrowding.

You did better than me on the 315 capacities. I found seating but not
standing capacities.

the 345s will initially be 7 cars when they run into Liv St prior to
May 2019. From that point they need to be 9 cars and will have the 2
cars re-inserted for running through the tunnel. I think when
Crossrail takes over Heathrow Connect in May 2018 that those trains
will be 9 cars but they'll run solely on the surface at that time.
There is no 10 car design. The 345s are extendable to 11 cars and
the central area platforms are all built to that length but may need
finishing / fitting out whenever the 11 car decision is taken.

Timeline

May 2017 - 345s enter service Shenfield - Liv St (surface) 7 cars
May 2018 - Crossrail takes over Heathrow T4 - Paddington "Connect"
service. 9 cars.
Dec 2018 - Paddington (low level) - Abbey Wood service starts. 9 cars
May 2019 - Paddington (low level) - Shenfield service added. 9 cars
Dec 2019 - Full through service Shenfield / Abbey Wood - Heathrow /
Reading. 9 cars.
Sometime in the future - trains possibly extended to 11 cars.

The point of the 9-car Crossrail Aventras is that they are the length of a
10-car train of standard stock, e.g. 315s, which are 20m long. So the class
345 cars will be ~22m long, making a 7-car train similar in length to an
8-car class 315 formation.

These lengths are a bit approximate as was discovered when they wanted to
run 12-car trains of class 365 stock from Cambridge to King's Cross.
Platform 1 was supposed to be long enough for 12-car trains. It is, but only
for class 317s. 365s are that little bit longer and wouldn't fit between the
starting signal and the scissors crossover, hence expensive platform
lengthening work.

No. All are long enough except 16,17,18.

[Someone may have said this before, but I haven't seen it.]

Before the complete rebuild, 9 and 10 were significantly longer than the
rest. Then were the east side (11 to 18) which I think stayed the same
length when rebuilt, while the west side (1 to 8) were a lot shorter
(something like 6 or 8 chains).

In terms of track layout
(getting to and from the fast lines), all of 5-14 seem to be possible,
and I have seen all of 8-12 myself over the years.

The Suburbans connect to 1 to 10.

The Mains connect to 5 to 14.

The Electrics connect to 13 to 18, though Bishopgate Jn means that a
train on the Up Electric can switch to the Up Main.

Wasn't the throat moved east and the west side platforms extended at the
country end?

Thanks for the details, complete as ever, Clive.
