Just seen on another forum that members are arranging a Zone 1 (except
Blackfriars) 'Tube challenge' where they aim to visit all stations in
the shortest possible time for a competition between members (not a

It has been raised that there may be problems with Oyster PAYG and
that users should instead buy a z1-2 Travelcard. What would happen if
someone touched in and didn't touch out again for say 3 hours, even
then they may touch out at a different location? Would there be the £4
minimum charge or would something else happen?

You would be charged two £4 fares. The system would consider the touch
in and touch out to be two separate journeys as they are more than 2.5
hours apart.

Indeed - though come September it seems as though new variable time
limits will be introduced that will vary according to the distance
travelled (calculated as the number of zones travelled through) -
which will in effect make the time limit a tad tighter for a great
many journeys, though still nothing that any normal A-to-B passenger
would ever need to concern themselves with.

Buying a Day Travelcard is the simplest way of avoiding any issues
about Oyster PAYG journeys 'timing out'.
