That way, I figure my unresolved journeys will only be on WAGN, where I
touch in at Liverpool Street (or use the validator at Seven Sisters)
and there's no gate/validator at Edmonton Green or Silver Street.

Now I'm confused again. I thought Oyster was only for use on the Tube &
DLR? At least, that's what the adverts infer.....
