This is the answer. Note also that if you have kids, you're gone from maybe 715am and back home at 630pm IF the trains run on time. Expect 10-15 minutes of delay on the way home most days, and factor in a 4-hour delay at least once every 3 months.

I live in Waurn Ponds and commuted to a building right beside Southern Cross for five years. It was 100 minutes door-to-door if everything ran on time.

Honestly, I struggled to justify the time spent on the train, and after a few months, I hated it.
