Rather than printing off card tickets, I organised e-tickets to

be sent to my mobile 'phone. This is a copy of them but they are not the best value off-peak returns at £22.45 each and that includes a two-together and senior railcard discounts. If I had chosen particular trains it could have been a little cheaper but we needed a degree of flexibility for our return journey. For the rest of the day in London, I used my Oyster card with both Andy and Mike using contactless. I planned our route to take advantage of two of TfL's permitted walking routes that, if completed within ten minutes, are counted as part of one journey despite touching in and out during it. The first route was from Archway (Northern Line) to Upper Holloway (London Overground) and the second from West Hampstead (London Overground) to West Hampstead (Jubilee Line).
