This arises from the thread on peak-only unit diagrams but when I was looking at the Chiltern timetable and operations the other day I was thinking: "what operations still retain a pre-Covid pattern"?
By pre-Covid in this case I basically mean an off-peak timetable with a certain frequency, then a significantly ramped-up peak timetable (rather than just one or two extras in the busiest hour). So the peak timetable showing 50% to 100% enhancement in frequency compared to that of the off-peak; for example 2tph becomes 3tph or even 4tph.
Chiltern would qualify as its base off-peak service is 5tph mainline, 1-2tph Aylesbury which ramps up to 9tph in the busiest hour, and 4tph, respectively.
I believe LNWR and Greater Anglia also still have a similar peak ramp-up, however AFAIK SWR, Southern and GWR do not.
Any others though?
This is not supposed to be a debate on whether we should return to a pre-Covid pattern of service but just a place to note where pre-Covid style timetables still exist.
