Seemingly addicted to going round London in circles, this boy and I are attempting to do the entire London Superloop in a day, starting with the SL10 from Harrow-on-the-Hill

Top of the clock: SL1 leaves from North Finchley and heads to the North Circular

ON A RAGGA TRIP: SL2 from Walthamstow Market will take us down to the docks

Superloop moquette

Here's where it gets crunchy: @tfl haven't made the Superloop amphibious yet, so there's a gap between North Woolwich (end of SL2) and Thamesmead (start of SL3). No ferry today because roads are closed for the marathon so it's through the tunnel and on a 301

TfL A dash round the corner at Thamesmead and we're on the SL3, Bromley-bound!
