GMT 3515 was one of Manchester's unique batch of six Leyland Titan PD2/34s with Burlingham bodies which became quite a common sight on the Saddleworth services in later years. Even these six were not all the same and this example is one of the three with pneumo-cyclic transmission with air change through a floor-mounted pedestal, the other three having electro-pneumatic change. 3515 passes through Oldham Market Place on 24th June 1975.
