Behold the Brave New World of instantly larger tunnels ((c) Gensler)
Ah well. Here we encounter the first of many clues that most of the press - hello, Evening Standard, i and Daily Mail, I’m looking at you - should have heard their bullshit detectors ringing long and loud. There is, in central London, only one potential route, and that is the long-closed branch of the Piccadilly Line from Aldwych to Holborn. Even then, it’s not a remotely credible use of the tunnels.
How it could link up, but won't ((c) Gensler)
Doesn’t sound so appealing now, does it? And the already stretched credibility of this idea soon snaps with the idea of connecting Aldwych to Charing Cross.
A Tube size train - the tunnels aren't much bigger
The flimsy nature of Gensler’s case also includes other suggested routes, which you can see on the accompanying map. One of these, just to show that all that collaborative design is right up-to-date, includes the proposed Garden Bridge. But here another problem enters.
