If Go North East have to allocate 6134, 6135,& 6140 to the 21 then to be fair in meeting customer expectations these vehicles should be fitted with WiFi and decent seat covering.

When I use the Arriva X12 if they have replaced the the allocated vehicle with a B7 ALX 400 I don't hear passengers complaining that they are getting an old ex London Bus. I suspect that when customers get the same quality seating and WiFi they remain satisfied and probably don't even notice that they have a different vehicle.

Go North East could easily stop all this noise about spare vehicles on the Angel by investing some of the fares increase in a few WiFi units and a new set of seat coverings for 6140.
