Buses on Screen: Heartbeat (Yorkshire TV drama series, 1992-2009)

Episode 2.08:
Features former West Wight Bedford SB3/Duple Vega UDL454:

Episode 6.10: The Championship
Features the wrecking of a unique Bellhouse Hartwell bodied Ford Thames coach (OHW407) in the livery of Smethwicks of North Yorkshire.

Bob Wingrove comments: "What made it even worse was that it carried a prototype Bellhouse Hartwell body, and was supposed to have been at a Commercial Motor show. The vehicle was in good nick and had not long been re-restored. The former owner was almost in tears when he saw what happened."

John Wakefield adds, "As far as I am aware the remains were acquired by a Mr Harrison of Rufforth after the Heatbeat crash. PSV Circle do not list OHW407 as restored so I don't think it got rebuilt."
Episode 7.1 Bad Apple
Bizarrely, the Ford Thames wrecked in episode 6.10 appears in the opening credits of season 7:

A coach depot is broken into, belonging to the fictional Kettley's Coaches. There are three coaches seen, all from Cumbria Classic Coaches. Bob Wingrove identifies former Lancashire United Guy Arab III/Roe 440 (MTJ84) in red livery. The green coaches are JPY995, a 1953 Plaxton Venturer-bodied Commer Avenger new to Heather Motors, and JTB749, a 1948 AEC Regal III/Burlingham new to Florence Coaches of Morecambe.

Although the three buses and an Albion truck appear in many scenes, they are rarely seen clearly, and only MTJ40 is seen moving.

Chris Hough adds that the break-in scene "was actually filmed in a former textile mill in Farsley which Yorkshire TV use as a studio for Heartbeat. It was formerly used for the interior sets for Emmerdale."

Episode 11.17:
Features 647BKL, a rare 1957 Guy Warrior with Mulliner body, in United Automobile livery with Whitby as its destination. New to Leybourne Grange Hospital, it was mocked up as United Automobile GU2. (thanks Dave Farrier - screencap by stronghold)

Another episode includes footage of a brass band and the shooting of a constable and also features preserved Lancashire United 440 (MTJ84) (confirmed by Stephen Osman). The episode also features a maroon/white Bedford CA minibus XPT454F.
Stephen Osman adds "another United bus used was Bristol K5G/ECW BGL29 (GHN189). Other vehicles that have seen use in the show include: Cumbria Classic Coaches 1954 AEC Regal III/Barnaby JVY516 (ex York Pullman no.66), Dennis G17 charabanc RD111".
