> As a commuter knowing you only have to wait a max (n)minutes as opposed to max 2(n) can be the difference between deciding to take a train or using some other means of transport Agreed. In my mind, the most important step to make is to increase frequency to the point where passengers think of trains in terms of frequency of arrivals, not by a specific timetable. At longer wait times, you plan around getting to the station early, hoping the train isn't late, hoping it's not too overcrowded, etc., each of which is a mental barrier to taking the train. At shorter wait times, all of these concerns disappear because "oh well, there's another one in 3 minutes".
