Nottingham City Transport 637 (17.12.2025)

I don't know if this allocation to the 9 was as a result of a single-decker shortage at TBG or a case of chosen random allocation but this Uni 4 branded E400 ended up on the route either way to somewhat boast more seats over the usual single-decker Yutong E10! 637 is seen on Carrington Street with a 9 to Wilford Hill whilst 633, an E400 in the spare livery, pokes into view with a 6 from Gamston as a green 10 branded bio-gas Scania follows the Uni 4 branded E400 on a service to Ruddington.
