Nottingham City Transport 309 (12.03.2021)

Two spares saw use on the green 11 route today, with the new style spare Optare Solo SR of 345 being on the route presumably in between workings from a branded variant before moving to do a possible purple 88 run or two and, following on from its run on the morning peak on the brown 15/16 route, this on the same route after taking over from 331, a green 11 branded Optare Solo SR. 309, complete with mask, is seen having just crossed Trent Bridge on an 11 to Lady Bay.
