Something I've just discovered, and apologies if it's already been pointed out in this very large thread, is a number of GN diagrams still have "Pathed as 365 EMU" in the description, despite the fact the class no longer exists (ignoring the preserved bits), and even has this description on Ely/King's Lynn diagrams, despite the fact 365s left this route on a regular basis much earlier than their full withdrawal.
Also, are there any plans for Southeastern services to join other operators in diagrams having the specific units involved revealed on the day? SWR services have this feature, including their 450/455/458/707 diagrams, which suggests the difficulty of a variety of rolling stock types on a multitude of different diagrams can be overcome.
