Not sure how long, but have noticed them in the past (glass divider between doors and seats).

If it was recent, I'd hazard a guess the stylised R logo would have been used.

Sorry to reply to an ancient post. The Nexus logo has been there at least 10 years possibly 15. They were put on the Heaton allocated units when Arriva / Northern Spirit refurbed them from the bench seats to the high backed seats they now have. It was about the same time as the old PTE livery was lost replaced by the Northern Spirit livery and Nexus logo on the outside
