Nottingham City Transport 309 (29.10.2020)

The 'ying' to 399's 'yang' is this ADL Enviro 200 MMC and that's because this is the short wheelbase spare and can be found running around on any midi-bus route but predominantly on Bridgford's when needed on a lot of occasions, as illustrated here. 309 is seen in Central Avenue, West Bridgford with a 5 to City Loop.
