You can see the autumn and winter timetables for 2017 on that PDF too, think that was the only time I've known the entire year's timetable variations be published at the start of the season.
The Autumn (illuminations) timetable has varied a bit over the last few years, but generally the daytime frequency would reduce to every 12 minutes, with a 10 minute frequency between Little Bispham and Starr after 6pm, increasing to a 7.5 minute frequency on Friday/Saturday evenings.
The typical winter running times have been 55 minutes, rising to 58 minutes for the summer season. When the tramway first reopened post-upgrade, the running time was 50 minutes, but timekeeping was atrocious.
The new 65 minute running time is interesting considering the old tramway used to be 62/63 minutes in summer and 58(?) in the winter with almost double the number of stops, single door for loading/unloading (twin cars aside), no priority at road crossings, and of course the old fleet working the service.
