I similarly spent a few years working in this space (TfL, digitising their data and website etc). It always struck me just how nuts the weekly meetings between different station operators and TOCS within the GLA would be, essentially a shouting match to determine who would have to keep their station open that weekend. Resultant timetable changes on the fly were always fun content to keep updated.

Timetabling (at that point) remained very much a manual process, I think they had to bring a poor chap out of retirement who wrote them by hand.
