(Hammer mystery series, 1984-5) Horror anthology series, entertaining but of variable quality. The budget seems to have been fairly limited, as evidenced by the examples below.

Episode 5: The Late Nancy Irving:
An American woman is met at Gatwick Airport and driven away in an Aston Martin. A sinister man is watching, and follows them in his own car. Parked in the background is a London Country Green Line TD class Leyland Tiger/Duple:

Later in the episode an establishing shot of Gatwick Airport features another Green Line coach, an RS class Plaxton bodied AEC Reliance, in a modified Green Line livery. Some of this class [were repainted with gold bands to mark 50 years of Green Line services, and were then redeployed in on the 777 Flightlink service operated jointly with Southdown:

We then see the Aston Martin arrive at the airport to drop the woman's companion off; the TD is parked in the same place, and there's another coach behind it. It's embarrassingly obvious that this sequence was filmed before the departure sequence!


Episode 10: The Corvini Inheritance:
High jinks filming with a London Transport MD class Scania Metropolitan.
The bus is first seen dropping passengers off in the dark:

In a daytime scene, one of the main characters, played by Jan Francis, is waiting for a bus on route 36B in London, but when it stops, it's nearly full and she can't get on. As it draws away, we see the registration, OUC438R:

A second bus approaches and this time she's able to board it. Registration is OUC138R:

All is not quite as it seems, however. (Where do I start?) Firstly all three buses are played by the same vehicle, former London Transport MD138 (OUC138R). Then there's the date: this was filmed in 1984. MDs were removed from the 36 route family in 1980, and by mid-1983 from London service. Next, the registration OUC438R on the back of the bus is fictional. Then there's the location - this street was not on the 36B route. And there's the bus itself. 36B was run by Peckham garage, which had MD1-111 allocated. MD138 was one of the batch (MD112-64) allocated to New Cross garage, and never operated from Peckham. In fact, at the time the bus was owned by Stephen Smith, who provided some of the background when I posted this on the 'Remembering Metro-Scania & Metropolitan Buses' Facebook page.
