My apologies - have sought clarity and it looks like it is indeed the 9th December (Sat) for the 329 move to take place as it is the whole allocation moving from Palmers Green to Wood Green.Sometimes, particularly in this part of North London in recent years, a part allocation on a route can get transferred, and this often relates to the Monday to Friday element only. In such cases, the actual move would take place on a Monday but the official date of the change will be the previous Saturday. It's always Saturdays, used to be Wednesdays up to about sixty years ago! Two of Wood Green, Palmers Green, Tottenham, Edmonton, Stamford Hill and Enfield garages were usually involved.
