Given I've since had further news regarding the Olympians, I can reveal the full details.

From next week, Dennis Trident/Alexander ALX400 17025-34 (currently based at Hull) will be transferring northwards to Stockton to replace 16831-40. All 10 are expected to be here by the end of the School Easter Holidays. As such, Stockton depot will finally become fully low floor within the next 2 months.
