Good point.


Except that I was forgetting that the travelcard is still valid at the
point of touching in, so the OEP still needed.

It's just not as common as starting the journey at a London Terminal.


The typical situation is you've got zone 1 - 2 and get on at Charing
Cross heading for Slade Green. *You need the OEP if gripped between
Greenwich and Slade Green.

The journey begins at Charing Cross, which is an NR station.

But has an adjacent underground station. Many users will approach it such
that calling at a tube station won't be a major inconvenience.
