Ladbroke Grove, augmenting diagonals with a 3/1 Twill Pickering.

Ouch.

*Flumuxed* Bifrucating adjacent stations St Paul's Bank capitailing on Twill but confounded by Pickering.

Looping around Pickering problem by using the Saintly prefix method. St. Oval. Twill ratio at 4/1. LV forced to minimum 3.6 on Northern line. Tea and buns served in 5 minutes. Becks squared on the diagonals. Blue token surprise!
