This may get Dave interested in them:
The opening titles of Get Carter (1971) feature shots of the journey to the north on the East Coast Main Line, filmed from the front of a Deltic, and the interior of the rolling stock. Another Class 55 in rail blue livery passes in the opposite direction. Some of this footage is shot at Selby as the train passes the BOCM factory.
In the same film during the scene in which Carter is checking his late brother's car in a scrapyard, one end of a Deltic can be seen leaving shot over the viaduct in the background.
