The route from Grayswood Avenue followed the Service 7 route to Moseley Avenue, where it turned left to follow the Inner Circle route as far as Cash's Lane, after which its route was shared with the other Alfred Herbert Service to the Edgwick works. It then went forward to the other works in red Lane.
