@renbymon this sounds like a cool day out. Not gonna lie.
As long as we get to go back snd ride the new ones afterwards…
@feliciarabbiton Assuming some of the longest trips on each line (Epping to West Ruislip, for example) it'd come to somewhere between 8 or 9 hours (7 hours 44 minutes if you never have to wait). That would get all five lines in with some bus journeys and a trip from Morden to Startford using the Croydon Tram, the Overground, and the Elizabeth line.
@feliciarabbiton I'd have liked to put the DLR in too but that may be a bit too much.
