Also posted this list of services that do not serve the City Centre or only certain journeys do on another forum but for different reasons as to why I'm doing it here. It's part of the reason I think First is going to be fairly okay for the LEZ needs. There are so many services outside of the city centre that investment can be held off for granted the 34/34A/241/242 and 254 have had newly branded buses already. Actually, a lot more services than I first realised.
