. Oops - wrong thread!
You are correct. With new stock introduction there will often be a number of the cyclic diagrams that require some of their content changing (eg associated ECS moves), so it is easier/better to re issue all the base diagrams in their required new guise at an earlier timetable change date, and back fill with older stock as necessary, as the old order will be gone before too long (in theory) and the new order can just slot in without reworking stock and crew diagram content along the way.Thanks for confirming, interesting way of doing it. Guess it means they can be replaced at the earliest opportunity when it's possible to do so.
