2021 - Update 2:
Another week of lockdown means its another lookback to the 2020 archives. My favourite bus in the previous NTA livery used by Go-Ahead is the ex-GT class, 119xx, series. The yellow and blue suits them quite well. But they are significantly outnumbered by the later Wrights (SG-type) vehicles, there being only 12 119xx vehicles in the fleet. So I was fortunate that when visiting the 17A termini at either end back in September 2020, that a 119xx bus awaited me.
