Ah, Stagecoach Supertram its been a while since you changed your timetables! After a couple of weeks of stability there will be another change as from Sunday 6th December although this will only affect the Yellow route which will see an increased frequency from this date.
Presumably with the Yellow route running to Meadowhall and shops now having reopened (and with Christmas fast approaching!) the frequency on this route will return to normal levels with trams up to every 10 minutes in the morning and evening peak, every 12 minutes during the day and every 20 minutes at all other times.
The Blue, Purple and Tram-Train routes will continue to operate to their revised timetables for the time being.
The timetables for all routes are available for download at https://www.stagecoachbus.com/news/yorkshire/2020/december/supertram-service-changes
