If the 22 & 24 are now interworking, which judging by the reportings this morning seems to be the case, I hope something is done to the route branding, so it's not specific to one service i.e. 22 branded StreetLite's. Just a thought, considering that the 23 is supposedly joining the Sapphire brand next year with refurbished Pulsar's, would it not be an idea to put them all in the new style Sapphire livery?

Would also be nice if all the X21/X22 E400's were in the same Sapphire livery.
