Strangers (Granada police series, 1978-82)
Bulman arrives in the series by coach, but apart from two differently styled Duple Dominant coaches of National Travel, we don't see much: Episode 2.02: Call of the Wild
Quick view of a Lancashire United Daimler Fleetline/Northern Counties: Episode 3.01: Retribution
Disappointingly just a closeup glimpse of a passing Routemaster at Euston: ....and an MD-class Scania Metropolitan: Episode 3.04: A Racing Certainty

London Transport Routemasters pass a DAF/Plaxton near Trafalgar Square: Episode 4.01: The Moscow Subway Murders
Lots more Routemasters!: the lead vehicle looks like RML2665 (SMK665F), followed by RM1026 (26CLT) and RM767 (WLT767), also RML2356 (CUV356C): There's also a Red Arrow AEC Merlin: ...and a Leyland B20 Fleetline at Bank Underground station: Episode 4.03: A Dear Green Place
An episode set in Glasgow ends with a single decker bus on a motorway: Episode 4.04: Stand and Deliver
A coach full of tourists is robbed. It's JNX633V, a 1979 Ford R1114 with Van Hool body: We also see a Duple-bodied coach next to a truck stop: Episode 5.06: Charlie's Brother's Birthday
A car chase passes a Ribble bus garage - parked outside is a Duple Dominant II bodied Leyland Leopard:
