TfL have added the new fares to their website, but they’ve made a couple of errors. The first one is a useability issue; rather than have the new fares on special pages linked to from the current live pages, they have instead copied the current fares onto special pages and made the new fares live. I guess it’s not too bad given that you’ll think you’ve got a bargain when you’re charged less, but they really ought to keep the current fares in the default place.
The other error is far more serious.
