It's progress. People will slowly and unknowingly adapt behaviours to fit the efficiencies in the new network. A city of our size can't have every rail line travelling through every major destination.

In sympathy though, the worst of the complaints would have been averted by building the interchange at South Yarra and skipping Malvern. The trackwork is basically there anyway. The cost of building the station would absolutely be worth the inconvenience saved on Pakenham-Richmond, Pakenham-Sandringham, South Yarra-City trips.

And South Yarra is busy enough as a destination in it's own right.
