Hope I'm not repeating someone else.
3977 was on the 'Orbit' services yesterday and 3964 was being used on the 'Citylink' 58.
There was also a Vyking (which I forgot to catch the number of) operating the 58 too. I was surprised that the driver was using the centre door, although I suppose the bendies do use the centre doors. It was really slow on the hills - don't think it reached more than 5 mph on Split Crow Road or Coldwell Lane!
