Express Suburbans - was Connex loses

["Goldie" <goldicom@powerup.com.au>]

Perth peak suburbans have a good practice.

One train express first half of route and all stations the second half.

Next train all stations the first half and express the second half.

There are a couple of key stations in each section they all stop at.  And
express means express - Don't know what speed they are doing but must be
100k and maybe plus - and ride real smooth to boot!

Longer lines in Melb may need different express proportions due passenger
profiles, say only 1/3 of section all stations.
