Traditionally, as already seen, driver training was done using a normal service bus with temporary 'L' plate signs front and back. Because it was usual to remove the window behind the driver to improve communication, you would usually find the same buses used on this sort of work as they had been adapted to make removing that window easier. I don't recall seeing Manchester buses on these duties in Saddleworth very often and this one caught me by surprise on 25th May 1971. It was 3424, one of the first batch of Metro-Cammell PD2s based on the Orion style rather than to Manchester's individual style with a more upright front. Although these were regular performers on the Saddleworth services from new and for many years after, it is the only picture I took of one in the area. The wooden sign to the left was a temporary hoarding advertising the 1971 Saddleworth Festival of the Arts, an event held every four years which attracts artists of considerable stature to relatively small venues.
