If I may stick my nose in the debate regarding the new B9TLs, I'm inclined to say they were built before 2012. The reason why I think this is because of the interior lighting. The 12/62/13/63-reg batch have clear white lighting, whilst the 11-reg batch have slightly "creamier" looking lighting, and in my view, having seen them yesterday, the new Red Kite B9TLs have this.
As always though, I'm probably wrong haha.
