Hi,
I received an answer from TfL about this fare calculation. They just said, that it’s “WNC to [U1] NR only Off Peak £9.50” fare, which still says nothing to me. I can’t find that fare anywhere on TfL’s site. Assuming that £9.50 is one way fare, it’s still £19.00 both ways, not calculated £18.90. They didn’t say anything about extensions or caps calculated. I believe that the fare was calculated correctly, but I’m curious what is this mistery fare applied.
Greetings
Jacek
