I still feel that the 57 reg Enviro 400's aren't as anywhere near as bad as some people make them out to be on here, don't know if it's just down to the locality of forum members to the routes but on here there is far less odd workings reported on here on the X21/X22 than the other Sapphire routes and half of the time the odd workings on the X21/X22 often seem to be down to the E400's being allocated elsewhere (usually X14/X15/X18). If you think the X21/X22 are bad, I suggest visiting Darlington and seeing our rotten Omnicitys on the MAX X26/X27 and X66/X67.
