It'd be an interesting exercise to compare Australian suburban
operations with overseas counterparts. The Zürich S-Bahn has quite a
lot of single-track sections, and they manage to achieve some rather
impressive average speeds and levels of service… but then again, to the
Swiss timekeeping is of national importance.
Other than having an unnecessarily padded timetable and too many level
crossings, the one thing that could permit more services on the Upfield
line is the addition of a second platform at the terminus. It'd be a
whole lot cheaper than duplicating the remaining section, and would
probably permit ten-minute frequencies.
