Crossrail Elizabeth Line trainset unveiled
http://www.railwaygazette.com/news/t...-unveiled.html

"UK: The first of 66 electric multiple-units for the Crossrail project was unveiled by Transport for London at Bombardier’s Derby factory on July 29.

Following dynamic testing at the Derby plant, the first train is to undergo trials at the Old Dalby test centre during August. This will include carrying more than 100 tonnes of weight to simulate passengers. A car is also to be sent to a climatic chamber. Once trials are completed, the test equipment will be removed from the first trains and the interiors will be fitted out with seats before delivery for passenger service.

The Class 345 EMUs are part of Bombardier’s Aventra family, and according to TfL production in Derby is helping to support 760 jobs and 80 apprenticeships. Barber & Osgerby is acting as design adviser.

The EMUs feature wide gangways, air-conditioning, CCTV and real-time travel information, and are equipped for regenerative braking which is expected to result in energy savings of up to 30%.

The Class 345 is scheduled to enter service on TfL Rail services between London Liverpool Street and Shenfield in May 2017. The first trainsets will initially comprise seven cars and be 160 m long to fit the existing platforms at Liverpool Street. Nine-car sets 200 m long with a capacity of 1 500 passengers are expected to be introduced from May 2018, initially running between Heathrow Airport and Paddington.

The full route linking Reading and Heathrow in the west and Shenfield and Abbey Wood in the east via new tunnels under central London is scheduled to open in 2019, and will be called the Elizabeth Line.

‘The Elizabeth Line trains, which are a great showcase of British design and manufacture, will be running on part of our network within a year’, said London Transport Commissioner Mike Brown at the unveiling event. ‘The trains are fully accessible, will have air-cooling, and once the whole line opens, they will help our passengers move more easily into and across the city every day.’"


Thanks. They seem to have put the full Elizabeth Line map over the door
at 1:12 ... surely they will need a Liverpool Street - Shenfield only
map initially!

So is it air-conditioning or air-cooling? (Both terms used in the last 4
paragraphs.) After the fiasco of "air cooling" on the New Routemaster,
TfL should be more careful in describing it. Hopefully proper air-con
as on LU's S stock.

The seats look about as well padded and comfortable as a slab of granite as
seems to be the norm these days.

Why did they need a completely new type of train anyway on both crossrail and
thameslink. What would have been the problem with ordering another load of
electrostars? Surely it would have saved 10s of millions in design costs.

I don't suppose the maps are applied in the factory with the production
trains. They'll be stuck in and updated as needed by the operator.

But will the initial trains even be labelled as 'Elizabeth Line'? I
thought the new name would only be used once the trains can use the tunnel.

I'd hope so too. These are just next-gen Electrostars, so the aircon should
be similar.

Aventras *are* the generation of Electrostars, with updated technology,
lower weight and compliant with the latest safety standards.

The DfT ordered the TL class 700s, and did it in such an inept way that
Siemens won, not because it was offering a better or cheaper train, but
because the company had a better credit rating. Had the trains been
ordered through a ROSCO they'd certainly be cheaper, and would probably
have included features that the civil servants forgot, such as tray tables
and wifi.

Some of that is already in place. Ventilation has been significantly
improved in many stations, and I think some use heat exchangers to cool the
air using pumped ground water.

As for the trains, the NTfL is intended to incorporate saloon cooling, as
well as emitting less heat in the first place. See page 24 in
http://content.tfl.gov.uk/ntfl-feasibility-report.pdf

There are doors to the service tunnel and it is at higher pressure in
case of fire so it doesn't really play a part in heat removal. There
are air shafts linking the two running tunnels and there are cold
water pipes in each tunnel to provide cooling.

The other difference between the Channel Tunnel and the tube is there
are no stations so limited braking and acceleration to generate heat.

Wasn't the need for an upgraded cooling system one of the major reasons
for the cost over-run and delayed opening of the tunnel?

http://batisseurs-tunnel.com/wp-content/uploads/2015/03/1-Le-Projet-Tunnel-sous-La-Manche_C1.pdf
says

Cooling system: compensates heat from air friction generated by trains,
and heat produced by engines or electrical equipments. It is based on a
closed circuit chilled water, and includes 2 cooling plants, total
40 MW, located at Sangatte and Shakespeare Cliff, supplying cold water
(4 degree C, 220 l/s) through 200 km of pipes of diameters 400 and
320 mm.

There's more in

Out of the tunnel, there's a cooling plant at each end. I guess it's
configured as 25 km out and return rather than all the way through.
The plants supply water at 4 C, no idea of the return temperature.

Yeah, and that means that they don't have to worry about the stations
being uncomfortably hot.

No they won't. TfL Rail applies until Dec 2018. It will apply even
when TfL take Heathrow Connect services in May 2018. All changes come
Dec 2018. See the footnotes to this press release about Paddington
Bakerloo Line reopening.

It replaces Heathrow Connect, which terminates at T4. HEx has T5. But I
still doubt the long term future of HEx. If it gets merged into Crossrail,
then all the terminals would be served by the same Tube and Rail services,
which would be much simpler.

What's particularly confusing to a visitor today is that the HCon station
in T4 is labelled as a HEx, not a HCon station, despite the fact that only
HCon trains serve it:

If/when the western link opens, and there are through trains, then I'm sure
Crossrail will have to serve T5.

I haven't followed that story closely - so Siemen's superior credit

One imagines that the missing tray tables must have been bought up by
Siemens.

Missing wifi I can kinda understand - those who really need/want it will
have their own mobile data connectivity, and it's yet more electronic
kit for the train - but no tray tables is a daft omission.

From
http://www.thameslinkprogramme.co.uk...-trains-QA.pdf

"It has been decided not to have tables in standard class. Passenger
research for the rail watchdog, Passenger Focus and London TravelWatch
showed that people recognised the main priority was to maximise capacity.
Seat tables are a nice to have but they also slow people down getting on
and off trains – and we’ll have just 30 seconds to get people on and off
these new trains in central London.
Our priority is to get more people from A to B as quickly and as reliably
as possible. These new trains will give us more carriages and more capacity
and much better reliability than existing trains, which is what people
want.

....

Wi-Fi was not included in the original specification laid out in 2008.
However, the trains have been designed to make it as easy as possible for
Wi-Fi (or an alternative next generation technology) to be fitted."


Of course, the actual order was confirmed in, I think, 2013, not 2008, when
discussions first started. So there's really no good reason why the spec
wasn't updated to include Wi-Fi in the intervening five years of debate,
discussion and negotiation.

The reason it all took so long was that the DfT wished to place the order
itself, as it thought it could do better than the hated ROSCOs. The
manufacturers had to finance the trains, as the Treasury wanted the
purchase to be off the government's books, and that's where Siemens (with
its much better credit rating) had the advantage over Bombardier. Of
course, the government could have borrowed the money itself much more
cheaply than either manufacturer...

It is noticeable that the 365 'refresh' has removed the tray tables,
procured by the very same TOC.

They were of limited usefulness: had a hole for a cup and a small space, but
not enough to put much on, and tended to collect dirt. However they were
also a useful shelf to prop up a laptop.

Is there any plan to fit them with wifi post-delivery?
And do they allow or block mobile signals?

I can't believe the 365 tables (there are still some I'm sure) are large
enough to affect dwell times.

No hole for a cup. Your memory is faulty.

Didn't one lot of Virgin X-Country trains get covered with some form of
foil wrap that blocked GSM signals?

The point was aesthetic rather than a deliberate attempt to prevent "I'M
ON THE TRAIN" conversations but nevertheless that was the net effect.

It's a mixture of satellite and HSDPA mobile. Coverage can be very
patchy outside of urban areas. The main problem with the Elizabeth Line
will be whether there's any mobile coverage in the tunnels. Existing HEx
tunnels do have GSM coverage.

Assuming a unified fares structure, does the layout preclude HEx

taking the tunnel and going to Abbey Wood, say? I can understand Heathrow
passengers not wanting an additional 6 stops between Heathrow and
Paddington.

Actually, I don't think I've seen the service pattern fully described
anywhere. (ie which branches will be joined together, what will fast and

Interesting. That new phased array certainly makes more sense on a moving train

No, only the Relief lines are connected to the tunnel. Trains on the
Main lines would have to cross the Reliefs on the flat to access the
tunnel.

From memory, there will be four Abbey Wood trains an hour to Heathrow.
The two Reading trains will go to the Shenfield branch. All the
Crossrail trains are, I think, stoppers.

I bet the tunnels will have leaky feeder aerials for 4G or some other radio
technology. It's a well-established technology. At work (still Philips then)
we did most of the central London tube stations for emergency coverage after
the King's Cross fire. That was for voice comms. Data is probably easier.

I'd be surprised if there isn't, but then I'm still surprised that the
HS1 tunnels are not fitted. After all, they will have had GSM-R
installed.

Specify the wrong numbers of trains and you get inner suburban trains used
on long distance (Portsmouth fast) services.

How likely is it that anyone other than the driver will actually be on the
train for that length of time? The routes and stopping patterns seem to be
arranged in a way that the overwhelming majority of journeys will be a lot
shorter.
