My only frustration with the trains is the 20 min gap between the 8:15 and the 8:35 from Monday to Friday. Why the big gap in peak time when the rest of the time they're 10mins apart? It makes the 8:15 exceptionally busy & if it's ever canceled, getting to work is a nightmare. To add to frustration, it's a better timetable on Saturdays at 8:17, 8:26 and 8:39....grrrr.
