(BBC crime series, 2000-11)

Episode 3.3:
Chris Hough notes: “Near the beginning Boyd is looking out to sea pondering a lost cockle boat while below him you can see a Mercedes Midibus. The episode looks like it is filmed around the cockle sheds at Leigh on Sea, but I am not well enough acquainted with the area to know which companies operate in that area.” Here's the shot, can anyone enlarge on this?


Episode 3.8
One of the characters is seen boarding London Routemaster RM545 (WLT545).

Episode 4.2
Chris also notes “The episode shown Monday 12 July 2004 featured a suspect boarding a Dennis Dart in an all red livery. The bus was chased on foot by one of the detectives investigating the case. The bus was devoid of fleetnames.” This was former London Buses DT1 (G501VYE), a Duple Dartline-bodied Dennis Dart, by then with Mediabus of Romford“</i>:

Also seen in the sequence is this Dennis Dart SLF/Plaxton Pointer of London United on route 33.

As the chase progresses across Hammersmith Bridge, the Duple Dart is passed (twice! continuity glitch) by Armchair DA146 (T146AUA, a Dennis Dart/Alexander) travelling in the opposite direction on route 209:

The Route 120 wound up on the front of the Duple Dartline Dart is fictional, but Route 33 did feature this type of bus previously.
Steve Bunce reports a scene “on the platform of a moving Routemaster between Trevor Eve and David Walliams. Couldn't ID the bus - did anyone else get a view of it?”
