A lot of love for the Citaro diesel on here. As a former driver I can say they were awful to drive and very temperamental. Arrivas Pulsars were are far superior bus to drive. Not sure if the cab layout of the electric version is better though.

Doesn't/didn't (delete as appropriate) Go Ahead have a plan to be all hydrogen and/or electric by a certain date? If so and coupled with the loss making situation I'd guess that the only buses GNE (not alternatively powered) will receive will be preloved from either Manchester or London.
