  • Good work Ruserius. Mine was the northern portal for the Elizabeth line tunnel under the Thames on its way to Abbey Wood. I'm still going to call it Crossrail

    Yep. Good tag, I went down a real Crossrail wormhole last night as I've not really been following the project. The North Woolwich Elizabeth Line Crossrail Portal sits on what used to be the North London Line to North Woolwich and was where they lowered in the boring machines to dig the tunnel under the Thames.

    Between Connaught Portal and North Woolwich Portal Crossrail uses the old Connaught Tunnel which goes under the Royal Docks. It's the only existing tunnel used in the project and they had to drain 13 million litres of water from the dock above to get at it to do the work, which included removing 135 years of coal and soot that had built up.

    I know it's running horrendously late but it is a pretty impressive feat of engineering nonetheless.
