first day of school to be extra cautious time wise, ill probably leave home if I'm catching the bus to the station, at around 6:30, arrive at station around 7:00, and then catch the train to flinders then to south yarra. Also there are 4 lines you can catch, the cranbourne/pakenham line, not to be confused with cragieburn which i got confused once with, sandringham, and or frankston lines
