Except that (if I've got this right) in the evening peak you can use
off-peak tickets on the slower Turbo services but not on the HSTs, at

information is rather hard to come by.

Posters are up & visible at Paddington.....
And that is unlikely to change under Crossrail - just that they'll
need to change trains at Maidenhead / Reading.to get to Oxford in the
evening peak.

It won't be cross-platform - fast London's will leave from current

AIUI existing 5 & 8 will be the Down Main platforms, 9 and a new face
opposite it will be theUp Main platforms, and the Relief/Crossrail
platforms
will be two new islands beyond that.

You are correct - I got my current platform numbers in a mess!

Do they have any choice? Permitted development on the railways means
that they don't need planning permissions....

Sorry to contradict, but they are being developed by a single NR team,
with a single manager at the helm. I know this to be true because he
gave a presentation last week, at which I was present.

Thanks for this update.

4. NO-ONE has mentioned the plethora of hybrid battery-equipped
rollingstock
currently prototyped, on trial, in low volume production etc around the
world. Given Crossrail's gestation, can I assert with some confidence that
by then it will be quite normal for trains to extend a moderate distance
beyond the wires or juice rail. 25kV to Reading would not necessarily be a
pre-requisite to CrossRail service by the mid-10s.


As a mechanism purely for getting ECS Crossrail stockl to / from the
Rwading Depot & Maidenhead - yes, I guess this would be a possibility.

5. Also absent from discussion so far has been AirTrack. In some other
forums, we hear that BAA are firmly behind AirTrack. AIUI, provision has
been made in the Heathrow 5 station box for them.

Correct.

The discussion suggests
that HConn/Crossrail will run through to Reading via H5 and AirTrack.

Hmmm - brains trying to do overtime again?.....not a chance! Why on
earth would the DfT want to spend a lot extra on dual-voltage systems
to enable Crossrail to run on the third-rail system? Secondly,
AirTrack will be a BAA service, just like HEx - so BAA will purchase &
run their own trains for their services....not state-owned Crossrail
trains.

Those
with local route knowledge can fill me in here, but once the link is made,
basically would dual-voltage stock (one assumes Bombardier will have
recovered from their supply line and quality management difficulties by
then - ) provide a through Crossrail all-electric service?

Getting the Crossrail stock from the new Platform at REading back to
it's depot will also be somewhat of a challenge, as there is no
connector in the plans from the Airtrack line into Reading with high-
nuumbered Reading platforms, and thus a route to the depot. It's self-
contained. There is also an AirTrack depot shown in those plans, but I
can't remember where it was to be located....

The enhancements of the track at Reading as part of
the £425 million station redevelopment would also pave the way for
Airtrack
trains to use the station. Network Rail is also working with the
Department
for Transport and British Airports Association (BAA) on the scheme to
connect passengers directly to Terminal 5.

Yup - that's the new platform on the south-east side of Reading
together with the BAA-owned route into the airport.
\Nothing to back up the Crossrail stock being used there.

6. Given the time frames for Crossrail, and the rather modest scope of
AirTrack in comparison, could it be that AirTrack is up, and through
electric services running Paddington - Reading before Crossrail starts?

Quite likely - another reason that it won't be using Crossrail stock.
It won't be built in time....

7. While HConn only goes to H123 (old H Central, made more sense!), AIUI
that's a commercial decision. The AirTrack scheme clearly envisages
HConn/Crossrail coming into the H5 box and extending west out of it.

Proof please - just where does it state or heavily hint this is the
case? I understood they will be using separate platforms at T5, with
no connections.

1) "Other benefits of the new, environmentally friendly
services include:
improved rail services in areas to the west of
London and in the Thames Valley
improved public transport access for the local
community to Heathrow Airport and its associated
transport connections into London including
Heathrow Express, Heathrow Connect and London
Underground services ... "

2) "BAA also has an aspiration to extend the Heathrow
Express service to Staines. This would mean an
additional two trains per hour in each direction. ... "

3) "The purpose of this addendum to the initial public
consultation brochure is to clarify how Heathrow
Airtrack trains could be powered and the options
that are being considered.
Overhead Line or Third Rail Electrification?
At the Heathrow Terminal 5 station it is not feasible,
for technical reasons, to operate Heathrow Airtrack
trains with third rail electrification. Therefore trains
in the Terminal 5 station and tunnels will be powered
using overhead line electrification (OHLE). OHLE
involves a system of supports to hold electric cables
some 4-5 metres above the tracks. This system
is currently used by Heathrow Express trains operating
between London Paddington and Heathrow Airport.
As the existing rail network uses third rail electrification
it will be necessary to change from third rail to OHLE
at some point between the Heathrow Terminal 5
station and the rail network in Staines.
The Options
Three options for making the change from OHLE to
third rail electrification are currently being considered:
1 change over as close to the tunnel entrance as
possible, while trains are moving. It is possible that
in this option the overhead lines may not need
to extend onto the SSSI at Staines Moor
2 change over from OHLE to third rail electrification
at the new Staines High Street station, while trains
are stationary
3 run OHLE all the way to the existing Staines station.
This option would allow Heathrow Express services,
which currently use OHLE, to operate to the
existing Staines station and is favoured by BAA
for that reason
In addition, the adaptation of the current rolling
stock used by Heathrow Express is being considered.
If it is possible to adapt the trains, the need to extend
OHLE to the existing Staines station could be avoided.
One of the benefits of extending the Heathrow
Express service to the existing Staines station
is that there would be a direct service from Staines
to London Paddington. Passengers using other
services from London Waterloo would also benefit
from a more frequent service to Heathrow Airport,
as they would be able to interchange at Staines
station and board a Heathrow Express train. ... "
