Trent Barton 506 (07.02.2022)

How this wasn't swapped for the Mango spare MMC of 145, on The Keyworth originally before being swapped for the branded Volvo of 730, on the Mainline route I'll never know and how 145 didn't stay out on The Keyworth instead of the red spare Volvo I'll never know! The first mention could be put into context though, as illustrated with 506's out of service blind that is featured here, the bus seen having temporarily come off the Mainline route most likely as a result of a shortage of available bus drivers.
