MCW Metrobus
Fourteen MCW Metrobus Mark II buses were acquired and fitted with guide wheels, which ran along the guideway's concrete edges. The vehicles were painted in a distinct livery, unique to Tracline 65, being silver with black and red detailing. It began operating in 1984. The trial ended in 1987 and all buses had their guide wheels removed and returned to normal services; the last withdrawn on 26 April 2008. One, fleet number 8110, is preserved at Aston Manor Road Transport Museum.
