Funny that. Northern said in their e-mail reply last week that they had been in contact with Clitheroe ticket office and it was they who confirmed that the ticket was still available. I'm pretty sure that it was listed on brfares quite recently and it is also on my Avantix Traveller CD from c2011. I'll have to make some more enquires with Northern and may pop into Clitheroe station and ask.
As for the East Lancashire Day Ranger - hasn't that been withdrawn recently too? It seems like all the through train+bus tickets from East Lancashire to Yorkshire have now gone.
You'd have thought that the local rail campaign groups would be kicking up a fuss but nothing is mentioned on their websites. Indeed, Ribble Valley Rail and Clitheroe Line Community Rail Partnership are still promoting the Clitheroe Bus ticket and the East Lancashire Day Ranger on theirs.
