Crossrail is a huge project tunnelling out a new railway line under central London. We featured the Crossrail “live” maps showing the location of the Tunnel Boring Machines (TBMs), back in September 2012. However things have picked up since then and the project has reached its maximum state of activity, with six TBMs currently toiling under the capital – and one which has already completed its job and will now be buried in situ.
The “live” map can be viewed here – it is updated every couple of weeks. Green represents completed tunnel while yellow shows tunnel that will be dug in the month or so.
Crossrail’s full route across London (including above ground sections) will look like this:
Even as Crossrail is being built, Crossrail 2 is in its very early planning stages. A consultation was carried out earlier this year, the results of which were published recently, showing strong support for the “regional” option, which like the current Crossrail, will extend outside of London. Here is an indicative map of where Crossrail 2 will go, should it be built:
