The Elizabeth Line (aka Crossrail) is go!

Incidentally, I was surprised not to see a thread / post about the new BBC series on Crossrail, The 15-billion Pound Railway, which started earlier this week. Very interesting stuff, and a lot of things I didn't know about the engineering challenges of the project.

Yeah, that bit about the tunnel going through just a couple of centimeters away from two others was fucking insane.
 
I thought it was quite tedious how they felt the need to include all the banter from the workers to give it a human interest element or some shit. A wolves fan, the no homo guy....yawn. Then was the over-dramatisation of everything and the OTT background music. Perhaps one for the BBC downhill thread.

There was a much more interesting documentary about the engineering challenges I saw a year or two ago, I cant remember what channel it was on though.
 
I really enjoyed tonight's episode. Very interesting challenges to overcome.

Never mind all the state-of-the-art GPS positioning and laser guidance. I still find it absolutely mind-boggling that two tunnelling machines working in opposite directions can meet each other with a margin of error of milimetres. The scene when one of the machines broke through, perfectly matching the circle painted on the wall on the other side, was just amazing.
 
I suppose, given the service frequency, you're probably expected to jump off to use the facilities at a station if caught short, then simply hop back on the next one a couple of minutes later.

Pretty sure they could be had under disability regs for not providing them, since the Disability Discrimination Act (DDA) does include several conditions where urgent toilet access is needed.

I wouldn't have though so. Legislation like that would have been taken into account on such a huge project. Also, I doubt it has an requirement for toilets on all public transport, as a lot don't have any. Buses, Tubes and the DLR don't.
 
So now they're talking about adding in Hertfordshire - how does that even work, some sort of connection near Old Oak Common?

Sounds like a bit of pre-election kite flying to me, ahead of the election, thin on detail and probably not practical within the current timescale given the commitments already made on the route. See also the idea of a new tunnel under the Pennines that Gideon was waving about.
 
Bloody hell we've already got the Overground, London Midland, Southern, Croxley Rail link (coming) and now Crossrail :eek: I know some people think Watford's the pits but it's not that bad surely :D
 
Anyone got any idea of noise levels from crossrail trains? I live right next to a train line which will soon be a crossrail line and I'm ok with normal train noises but wondered if crossrail would be especially loud?
 
Don't think they'll be any louder than standard electric multiple units that already operate on most lines around London.

If you live in West London, they will be quieter than the deisel trains they replace. Otherwise, no different.
 
Not the same trains or different lines? How come we don't get that in Essex?
Because the trains on that line (to Shenfield) are already electric. The new ones won't be any louder. In fact they may be quieter, as the track will be spruced up and modern trains tend to be quieter.

It's not just that though is it. Huge massive tunnels going straight through the centre of London, missing any existing tunnels, drainage Etc. foundations......wow.
 
They made a big deal about squeezing through a tight gap at TCR, I notice that Crossrail 2 is planned to stop there too! Might be a tight squeeze.

It'll be at right angles to CR1 and there's loads of space. The tunnels will pass between the two ticket halls. The "eye of the needle" from the programme is behind the Eastern ticket hall, under Charing Cross Road.

You can see stubs of tunnels that will form access to CR2 from the central line and from CR1

Thanks Crispy, that's a nice diagram. It'll be insanely busy around there in a few decades, won't it?

It will. Construction of CR2 should be less invasive though. The ticket halls have been built with it in mind, so they *should* just be able to open up the access shaft in Soho Square and do it all from there.
