Nottingham City Transport 431 (26.04.2025)

Over on the 10, a similar story occurred in which a spare ended up on the route although on that occasion, it was a case of a bus swap of choice, which saw the branded bio-gas Scania of 407 come off to be replaced by this bio-gas spare variant, as illustrated here. 431 is seen on Loughborough Road with a 10 to Ruddington.
