Speaking of EV64, I was on that bus on three ocassions and on the two of them there was an awful drilling noise coming from it. I don't know what it was. It was not the heating which is loud enough. This was very loud. It lasted for five minutes. Everyone was annoyed with it. I have been on a fair few of the Evs and none of them apart from EV64 makes this noise. It would be my least favourite of the Conyngham Road EV batch. Not ideal for the general public let alone wedding guests.
