Here's an announcement and industry briefing program about further development in the Perth suburban rail system, including the next generation of trains:

The latter presentation is particularly useful as it has a schematic map showing the extensions, for those not familiar with Perth place names. It also shows that they are going for the long-planned C series train which has four doors per car per side, though that's not set in stone yet.

This is quite remarkable in Australia as 4 doors per car is something you only see in metro trains overseas. Even the Sydney metro cars have only 3 doors per side per car. Dwell time is considered important in Perth. They can pull off the seating loss in Perth because of their fast journey times, meaning you're not on a train for too long - and you'll get a seat in due course anyway. Journey time, not distance, is the determinant of seating/standing ratios.

In relation to the network, it can be pointed out that, although it's not shown in this stage 1 plan, the future intention is to continue the Forrestfield/airport line to Thornlie, thus creating an outer circumferential line linking the Midland, Armadale and Mandurah lines. In future I believe there will also be a link from the Midland or Ellenbrook line across to the Joondalup line.

Note the proposed train station on the Ellenbrook line at Whiteman Park.... ;)
