The PTC Master Train Plan ( Working Timetable) shows milepost mileage via
Albion to Jacana thence via Essendon. In a separate column they show actual
standard gauge distance (317.4km to Albury).
Due to this break of mileage Tullamarine Loop and Somerton have very
similar mileages (about 22km, I think).
Out West in the Broad Gauge days there were three stations within a
kilometre or so according to the mileposts - Tatyoon was 231km via Cressy,
Maroona was 232 via Ararat and Great Western was 232 via Ararat. Nowadays
the mileages are via Cressy as far as Pyrenees Loop thence via Beaufort
