    Yes, I was being a bit facetious. It'd be nice if the two recovered ones get some re-use, maybe they can do the tideway tunnel then pick up Crossrail 2 after. There's a lot of tunnelling to come in the next couple of decades, with HS2/3 and possibly a new Pennine tunnel, plenty of work.

    On a topical note, hows the cooling of the tunnels looking? Are the trains and stations going to be as hot as it gets on the standard tube?

    Trains definitely will be AC. Stations, I think so too - the platform edge doors enable it.

    I presume they've designed/built the junction with grade separation to allow for the proposed frequency of service, and the crossover is just there for occasional diversionary use?

    Nope, I'm being confusing here by mentioning the junction and the crossover! I meant the junction (east of Whitechapel) being grade separated, i.e. the eastbound line for south of the Thames dives under the westbound line in a separate tunnel to avoid conflict with incoming westbound trains from the north-east branch. Some of the tube lines do this sort of thing, it avoids having a diamond crossing and allows greater train frequency by removing the conflict (for the same reason they built the Hatfield flyover on the East Coast mainline recently).

    Looking at this and this (GA sheets 18 & 19) I'm not sure it does.

    Yes the junction is grade separated and the caverns are at different levels.

    Great photos as always, also makes me think of the film Aliens. You should stick a cluster of fake Alien eggs somewhere out of the way for someone to discover :)

    You should put weird-looking carvings on the walls of the temporary tunnels, make little altars with indecipherable runes, piles of votive offerings etc. to confuse archaeologists of the future.

    Why is this bit dug uphill? Digging down would be easier, no?

    I imagine spoil clearance is simpler if it's gravity-assisted...?

    Also, you can dig uphill from a large take-off area, that you already excavated, into the ticket hall.

    If you dig down, you'd have to take up more space on the crowded surface to launch the machine, cart the spoil away, and so on.

    Could be wrong, await the expert...

    Zimri clearly not enough thank yous for putting these up. They are great. Thanks for taking the time, not only to post up, but for the explanations.

    Need a Civil Engineering porn thread. This is hardcore.

    It does look strange from that angle, but it's a standard (if stretched a bit) split junction.
