Set in Liverpool, one episode included a bus station scene. "This was filmed at MTL's Edge Lane works and featured
Liverpool Corporation buses from the Mersey & Calder B.P.G. (now Merseyside Transport Trust) collection, plus Ribble Atlantean 1686 (NRN 586) from the Ribble Vehicle Preservation Group collection along with at least one (possibly more) Leyland PS1 from the fleet of Maypole Coaches of Burscough." (thanks Ian Simpson). 1686 is a Metro-Cammell bodied Leyland Atlantean PDR1/1.
