They not only suffered from having non-standard engines, which proved problematic in sourcing replacement parts, but they did also have corrosion issues. 3789 almost made it into preservation a few years ago, but upon inspection there was severe corrosion underneath and an almost non-existence outer frame. Such a shame, as they were very good buses.
I know the engines in the 'express' ones were uprated, performing and sounding different to the 'normal' batch. But do you (or anyone else) know what the differences was between the two?
