Other than some Optare Solos, which are mainly used on the ‘shopping’ routes, and possibly one of the old Darts (you don’t see it for ages and then it reappears), the fleet is all double-decks. The 1 used to go straight to the Red Jet terminal, reached through a narrow arch, and then call at the Co-op on the return: this required small single-deckers, latterly Enviro 200s. Now it goes straight to the Co-op, which has a turning circle, and terminates there: there is no longer a problem caused by what vehicles can get through the arch.
