Well, as long as they will not try to "save" by cutting and de-scoping permanent structures - it's all good.

No new trains to be designed eh? Do I here odds-on for more 378s? ;D

The report actually says that the trains will be based on "tried and tested designs", which will mean no fancy untried technology. I imagine that there will still be plenty of competition for the Electrostar family (class 375-378), from the likes of Siemens (class 350), Alstom and the Japanese.

Hang on, Crossrail Ltd aren't the UK government, so how can they insist that stations won't be cut, when its up to the government, and they haven't decided yet?

I imagine that Crossrail Ltd have been asked to save x% from their budget and have been able to do this without removing stations and/or routes from the plans. Remember that in June, Philip Hammond, the transport secretary, did say that Crossrail would be build in full. See www.bbc.co.uk/news/10323035

They were going to design a new train? Why? When we have so many lovely trains already existing to choose from. That sounds like a worthy cut to me. In fact, you sometimes wonder if some projects pad their budgets with superfluous items that they can later "cut" when the pressure is on.
But yes, I agree that we don't want to cut things that we're going to have to live with later. So no to making the tunnels tube gauge. And make the underground stations as they were conceived. However, the revamps of some of the existing stations on the ends can probably be deferred. Does Ealing Broadway need a facelift to work? It would be a really-nice-to-have, but probably not essential, at least not in full. These can be done later when there is more money kicking around or when we actually ask First to pay for its own damn investment like Chiltern do.

Tube gauge would be better. I don't see why it has to be mainline gauge. If it was tube frequency rather than mainline frequency there would be a better service.
Its only going as far as Shenfield and Reading. That's not really any further than Chesham on the Met line.

Surely tube gauge is a thing of the past. It was brought in by the limits of the technology for the original tubes, the limits of budget for Victoria and the legacy of using already existing tube tunnels for the Jubilee.
Also, this service will be going to Heathrow and will displace Heathrow Connect. That would be a massive downgrade of service from the lush class 360s. We're already have to live with the consequences of making the Piccadilly line the one to serve the airport (and I assume the tunnels eliminate the possibility of changing it over to the District).
But that raises an even more important question. With Crossrail providing through services into Central London from Heathrow in a much more comfortable environment, we might expect significant movement from the Pic to Crossrail as it is a quicker and more comfortable ride. Could the Pic be dialed back? Or will it still cost £6.50 to get as far as Ealing Broadway and thereby make the Pic still by far the most economical route?

You want to send a tube gauge line to Reading?!! Do you mean SSR gauge stock? Chesham is to Maidenhead as Aylesbury is to Reading; its a long way further. Whereas Chesham tollerates SSR stock, and argueably Aylesbury would have been ok with A stock, neither would be acceptable with tube gauge stock. And Reading is about the same size as Watford, Amersham and Aylesbury combined. If you did mean SSR gauge then my apologies; 16-car S stock anyone? Where would the pantograph go however....

Isn't SSR stock gauge basically the same as NR gauge? The A stock in fact seem bigger than any NR train.
I was just thinking S stock for Crossrail. Looking at the pics, there are these hatches on the top. Are they based on a design that was intended to use overhead AC?

Why would you remove the Picc from Heathrow? Lots of people will still need the connection from places like Hounslow, Chiswick, Acton etc to the airport (lots of workers live in the immediate area) and won't really want to have to use alternative means.

It's the BAA that control the levy on Heathrow services. I'm sure that the Picc would always be the cheaper option, much slower service, smaller trains and no prospect of A/C anytime soon etc.

But that'll be its maximum frequency. The tubes will be eventually about 30-33tph.

Absolutely. And for that matter the 10 will eventually become 12; hopefully!

Regarding the trains, why can't they simply order more air-conditioned "S Stock", as a run-on from the current order, and insert two extra cars with pantographs near each end - that would do nicely. I heard that the "S-Stock" could be readily adapted to accept pantographs, much like the current Southeastern Class 376 trains, also manufactured by Bombardier...

Where on the Mainline network do they run a train to a station every three minutes (give or take 20 seconds). I'm not talking about places like Clapham Junction which probably has a train movement in the peak every 30 seconds in and out, but to a single platform - stop, open doors, dis & embark passengers and luggage, close doors and off; every 3 minutes?
ATO for the mainline anyone? Forget Crossrail, use the money to upgrade the tube network - which has the experience, knowledge and expertise of the best rapid transit system in the world - instead of trying to put another tube system in London.
LO is the closest NR has to a 'Metro' system, and they can't run trains on any sort of time when they suggest a 5 minute service NX/NXG - Dalston Junction. And the suggestion is to HALF that frequency?
All Crossrail is, is a milk cow for consultants; take them away and the line would probably only cost £4b, not the advertised £16b....

we have so many lovely trains already existing to choose from Glom, please delete Class 315s from your list if they are on it. I have to use the damn things from time to time between Chadwell Heath and Liverpool Street. Far too similar to 313s for my liking and I was pleased to see the back of them on the Overground. I'll be interested to see what sort of seating plans they're considering for Crossrail trains especially bearing in mind the likely passenger numbers. The wrath of Amersham Alan will be nothing compared to that of Romford Ron if he get's even a whiff of longitudinal seating only..........I'd be happy with 10 car 378s with a slightly modified seating plan to keep everybody happy.

The Brighton Mainline has a train about every 3 minutes in the morning peak heading to London!

As you bought up Clapham Junction, the South West Trains mainline suburban services are run at 3 minute frequency (with the odd 4 minute) all stations Wimbledon - London Waterloo. This applies especially London direction in the morning peak. ATO is/was planned for the central sections of Thameslink and for Crossrail. The Central line, which Crossrail will relieve, can't possibly be upgraded to give the capacity needed now, let alone in the future. The East London line part of LO will goto a four minute frequency when the Clapham Junction extension is opened, not quite your three minutes, but that is partly due to having several start points and sharing tracks with Southern trains. Crossrail will be fairly self contained and the three minute frequencies will be in the central tunnel section.

This applies especially London direction in the morning peak. A quick look at the timetable shows similar frequencies between London Bridge and Charing Cross on Table 199 (to which must be added the long-distance services as they are not shown on that table), so the frequency at Platform B at Waterloo East is of that order and through the double track section at Borough Market Junction (which carries Thameslink as well as all services to Charing Cross) is considerably more.

Quite how anyone could claim that London has the best rapid transit system in the World at the moment, I don't know. This is particularly notable when looking at the cramped, decrepit, hot, sweaty, overcorwded state of most central stations, the constant delays and disruptions caused by decades of neglect, and the complete inability to implement any sort of modernisation plan - even on the part of the line that is only 10 years old.

As mentioned above the SWT suburban service runs an impressively intensive stopping service between Vauxhall-Wimbledon (and then to about 8 different routes). If I'm not mistaken they all run from platforms 1-4 at Waterloo.

There are plenty of perfectly adequate train designs around that would suit Crossrail. Why re-invent the train? A good decision.
As for frequency, it is very difficult to get 12-car trains into and out of stations and maintain any more than 24 tph. Trust me, I've done the sums.

If these trains get any longer they'll be stopping at two stations at once.
"The next stations are Bond Street and Tottenham Court Road. Passengers for Bond Street, please move to the rear five coaches. Passengers for Tottenham Court Road, please move to the forward five coaches."
Never mind about interchanges being so long that you might as well alight and walk at surface, how about platforms being so long that you might as well get off at the previous stop?

I've seen on here someone say that in one of the tunnels on a metro in the US (Boston I think), there is a tunnel with a continuous platform all along the tunnel - the train just stops at various places along the platform but it's perfectly possible to just walk.
