I actually spoke to a driver at the terminus in Musselburgh earlier who said the new buses are all just about ready and they’ve been told that they ARE entering service early January!
I suppose if the 30 buses enter service on the 30, it would allow the following;
10 B7’s to be temp withdrawn from service
2 to go entirely single deck (usually 4/5 deckers on this
Maybe 8 7900’s to marine for 42 (45 doesn’t operate just now) 6 plus 2 spare
And 7 7900’s to central to give them 10 total for 12/24?
that would account for all 30 evoras!
