I was just gonna post exactly that PG but ya Bate me to it
Work on the Canary Wharf Crossrail station, which will be the first Crossrail station to be constructed, began on 15 May 2009. The six-storey structure includes plans for 100,000 sq ft of retail space and a roof-top park. At 256m long the station will be almost as long as three football pitches. Tunnel boring machines are expected to reach the site in summer 2012 and the station is due to be completed in 2015. Crossrail services are expected to begin operating from 2017 cutting journey times across London allowing travel from Canary Wharf to Liverpool Street in 7 minutes, Paddington in 17 minutes and Heathrow in 44 minutes.
This is one of the larger stations by the way.

It was you are right.This post has been deleted.
Can I be quite clear on one thing. There will be NO TUNNELING in Donegal , much less Arranmore
I am equally certain that Donegal people especially from Arranmore and Dungloe will work on Crossrail. Now we have done the obligatory Donegal Tribute bit can we get back on topic Condi

This is one heck of an Infrastructure project, and hits very close home to me, being a lad born in London myself.
Whenever I'm over there, you can be sure I'll be taking plenty of snaps!
Excellent stuff, I have been over to London a few times myself and I agree this project looks huge. When finished it looks to really link up many parts of London that are currently isolated from a commuting rail service.
One example would be in the suburb of Ealing, currently there is only two underground stations at Northfields and Ealing Broadway. This new line will extend these services out to west Ealing which is currently isolated from any rail services only the national one at the West Ealing station itself.
The most impressive feat will be that of the central city area where they will digging underneath the underground itself :eek:0 -

London in 1970 , same as Paris, had a very slow tube network that brought punters from big overground stations to the very centre. The busiest overground stations in Europe are Victoria Waterloo and Gare Du Nord and Gare D'Austerlitz in Paris IIRC. All are awya from the CBD and Government Districts although you could walk from Waterloo to Whitehall and Victoria to Whitehall in all fairness.
The French got the finger out and built the original cross shaped RER crossing in Chatelet les Halles. The Brits dithered although the tube was not as dinky as the Paris Metro. Most jobbies the Brits did post war were north south ( Jubilee down To Charing Cross and Victoria and some Picaddilly) . They ignored east west for years.
Then in the 1980s they built Thameslink North South from Brighton to Bedford but mainly overground or in a gullet. Finally they looked again at east west as Canary Wharf rose in a wasteland in the Docklands. Someone tapped Paul Channon for a large wedge of public cash and started Crossrail as a sort of Tory Nutjob alt.tube system.
Crossrail from Paddington to Liverpool Street has therefore been around for 20 years or more as a plan. It was always going to be a deep tube.
Crossrail in the mid 1990s was either killed in favour of the Jubilee Line which was extended east - west along the river or else the Jubilee Line went so far over budget that Crossrail was killed. I cannot remember the precise sequence.
Central London is served ( east west) by the low capacity central line ( mind the gap territory) and this was a New Central Line beneath it. There are other lines north and south of it. One is the oldest underground in the world near Euston.
Then Crossrail grew a hell of a lot east and west since c.2000 when it was resurrected.
West they added the Paddington western commuter services and The Heathrow Express to it.
They realised that Liverpool Street was not a good terminus and Canary Wharf was added . The Olympic Park was also added although it will not be done in time for the Olympics and thereafter I think it takes over fenchurch street service.
The Canary Wharf and Stratford ( Olympics) legs were extended quite a lot with a fenchurch St leg being taken over. Fenchurch Street is a small station. One plan even had it going to Ebbsfleet SE of London and Reading to the West. 50 Miles long at least but 20 miles on existing track.
It will relieve a LOT of pressure on all of London Bridge/Paddington/Liverpool Street Tube/Fenchurch Street and on the DLR.
Crossrail 2 is another early 1990s plan called the Hackney-Chelsea line but that will probably end up as as an Epsom Racecourse and Gatwick to Stansted Airport connection once it gets its opportunity to Bloat like Crossrail did since it was conceived.
It is many many years away Lets see how this one goes. 0 -

You would be right. The blue bits to the West and north east are all existing Overground lines that end in busy Overground stations on the fringes of the centre and London has a large centre of about 5 miles wide by 2 miles deep north/south.
The Red bit on the left is the Heathrow Express which can serve the City direct now instead of terminating in Paddington 4 or 5 miles from the City of London like now.
These are gonna cross over underground in future in an Interconnector scale twin tunnel but it is a very deep tunnel and the stations will be large, RER style.
The only NEW lines are the red bit in the middle and the entire section to the south east via Canary Wharf which is red/blue. The very last bit may the existing London Bridge - Dartford Line via Greenwich at Abbey Wood. It could be quad tracked (from my memory of it) . Abbey Wood is very near the first London Mega Project ....ever heard of Crossness Pumping Station ???0 -

I've been reading through the progress and there is some major work being carried out on the Canary Wharf station. A huge amount of water has been pumped and work is now starting on the station itself. It's planned to have a big retail unit also in the design. Am I right in saying this thing is going to cost £500 million alone?

I cannot understand the price of this either, its rather excessive. Even the £16 billion quoted for the whole project is a massive amount of money for one transport project in one area of the country, though the London greater area does cover 1/3 of the population.
Our MN is a Nissan Micra compared to their Bugatti Veyron Crossrail.Transport minister Sadiq Khan this morning (11 February) flicked the switch on pumps to begin the process of draining nearly 100 million litres - the equivalent to 40 Olympic swimming pools - from the worksite over the next six weeks
This kinda shows the transport policy in the UK. Our transport minister cuts the tape on new motorways where their one flicks on a switch for pumps, be it rather large ones.
There is a massive demolition job going on around Tottenham Court Rd alright, these photos below were taken from a guy in his flat nearby:

My memory of this is that they costed Jubilee at c.£1.5bn and Crossrail ( Paddington-Liverpool street but including the deep stations ) at £3bn .
Jubilee overran (a lot) and my boozing buddy Simon made a fortune out of the old gasworks that later became the Millenium dome because it was a VERY severely Contaminated gasworks not just a Contaminated gasworks.
He reckons he personally delayed the Jubilee line opening by 6 months ....he had an exclusive contract and he successfully insisted they stuck to its terms or else pay him a 7-8 figure sum to piss off
They would have been 1992 or 1993 prices. Now TCR station alone will cost over £500m and maybe even up £1bn on its own.
Just imagine what would happen if Bernard McNamara got the job and found a bottomless bog under Bond Street ???0 -

It really is. Both MN and DART Underground.
The only station that even comes CLOSE to the level of complexity involved in Crossrail is St. Stephen's Green, but that's all new build, no adjusting of other stations necessary. The Heuston station requires some adjustment of the existing station and erm... THIS is how they plan to do it.
It... doesn't really look all that nice.
But I shan't de-rail this thread...
Crossrail is an incredibly exciting and ambitious project, and since it's gonna be a good while before any serious construction/enabling begins on our own, it'll be great to keep track of this one.
First thing I need to find is the reference designs and environmental impact study. They're a good port of call for detailed information.0 -
Also remember that the key to shifting people in vast numbers is related to platform dimension and station dimension and intervals.
I think Dart Interconnector will be at 3 min intervals each way and 800 persons per train.
Crossrail will be able to shift trains at 2 min intervals like the RER and will have 1500 persons on each train.
As the lines are bidirectional the peak capacity of the Interconnector will be 800 punters x 20 trains per hour x 2 directions and Crossrail 1500 punters x 30 trains per hour x 2 Directions.
Most alight in the core stations of which there are 5 in Crossrail and 5 on Interconnector.
Lets say they all alight centrally for simplicity.
The 5 dart Interconnector stations will have to clear out 32000 punters an hour / 5 stations or 6400 punters each an hour from fairly shallow depth. Couple of seconds to surface.
The 5 Crossrail stations will have to clear out 90000 punters an hour / 5 stations or 24000 punters each an hour AND from a much greater depth, over a minute to surface. Lots of escalators required.
The London platforms will have to be bloody enormous ( c 6 metres wide like the RER) at depth as they must clear many more punters in 2 minutes than the Interconnector will in 3 minutes.
Then the EMERGENCY exits are a tad large in London and must factor in heart attacks with all those stairs 0 -
