The red structure is the remains of the original Greathead shield used to tunnel the Waterloo & City. It was left in place in 1898 and rediscovered in 1987.
Nice tube geekery there.

The shape of Tunnel Boring Machines to come. Turns out they’re reusing one from a previous attempt to dig the Second Avenue tunnels in the seventies. Cheapskates.
(It’s stiil a lovely machine. Again, the other pictures are worth a look.)
