Shall go with Gram's Conjunction and slip through the shadows to Marble Arch

I'll play the Schizoid Tangent with... Highgate, which became Archway (Highate), then Highgate (Archway) to end up as Archway...

And, I note, implicitly invoking the Piccadilly Ruling. Just as well I'm not trying to shunt from Ealing Broadway or we could have another Moon Over Morden incident. As things stand, Essex Road, de-quanging.

Simplicity can be beautiful - Highbury & Islington. Now just look at what has happened.

It's... all... opened up. That's quite staggering. Never in my years have I seen such a wonderful reduction as that. All players are back in ground state, the diagonals are open, all barriers are up, power is back on...

So I might as well take advantage and set up anew at Great Portland Street.
