If you are changing from the Central Line to NR, you do have to keep
your wits about you.

If you've already got your NR ticket, you have to touch out on the
platform (or it will assume you've gone to Epping or whatever).

But if you haven't got your NR ticket, you have to not touch out on the
platform, but touch out to get you through to the outside of the
barriers to where the NR tickets are sold (if you can find it).

Does it not charge you the correct fare if you touch out on the
platform and then again when leaving through the barriers?
