JT have no plans to put significant work into extending down to Windermere. They would say so, it would generate positive publicity. Also they have a very small team and it would take the devs potentially 3-4 months to instigate. Also the CCN Route is a DTG product, so JT will not be altering the route, just making a new timetable, along with revised Pacer/s. DTG "could" extend down to Barry Island, but we all know once a DLC is released DTG don't look back. (and yes I am aware that CCN was contracted out to Rivet, but officially it sits with DTG).
I’m hoping that Levenmouth and the upcoming Richmond extension on Mildmay set enough precedent for a Barry Island extension. It’s a decent little route but should’ve either been £25 or gone to BI for £30.
