I don’t get it ... With my point of view, one route with 15 stops has 15 timetables, each timetable describes the arrival time and the departure time of several trips at the stop.
There must be the same number of trips along the stops’ timetables. (Otherwise this is an other route). You mean, if somebody messed up and add an extra trip inside a timetable, this would be hard to figure ?
