Alternative Challenge Suggestion - London Overground All Lines

[RJSRdg]

Now that the various London Overground routes have officially received their controversial new names and colours, this opens up a new challenge:

Travel at least one stop on each of the LO lines in the shortest time.

Obviously other modes will need to be used as the Romford- Emerson Park-Upminster "Liberty Line" is completely isolated from the other lines.

Or maybe just an expanded All Lines with one stop on each Underground and Overground line, plus the DLR and Elizabeth Line?

Or maybe just an expanded All Lines with one stop on each Underground and Overground line, plus the DLR and Elizabeth Line?

Wouldn't then arguments start on whether to include the Tramlink, or Cable car. And if each Overground line is separate, why wouldn't the DLR be split into 3 lines, and the Tramlink into 2.

I like the idea of an LO all lines challenge, I have a route which is around 1 hour 25 mins, which seems like a nice challenge to do as there are quite a few in such a time range (especially for non-LU challenges).
