I recently picked up two Chiltern £9.55 advances from Burgess Hill to Birmingham Moor Street and the return leg.
These tickets seem to suggest both the Thameslink and Chiltern legs are booked services only, and I wasn't aware that these fares existed. I'm used to only one TOC's leg being a booked service, and connections being "whatever you want".
Do any others like this exist that anyone is aware of?
