The 808 existed alongside the 508 and 515, albeit without a specific service number, during the 1970s and most probably before that. The timetable below is the T. B. Vasey service circa 1976, but it is clear that both services are one and the same:
I have also included timetables for the the 508 and 515 from 1979 (easier to photograph). I'm sure I've already posted these elsewhere and was going to link to them but, alas, I couldn't find them:
As some of you will know, Whitley Bay was once a popular holiday destination, especially with people from the Glasgow hinterlands, and Lanarkshire, which is most probably why the 515 existed.
