What is the posted speed restrictions for the Kwinana-Forrestfield rail line? Through Canning Vale, at least, Southbound trains appear to move a lot faster (looks like 70kmh) as opposed to northbound trains puttering along at 20-ish clicks.

The track speed is 80kph both directions. However there has been a temporary speed restriction between Cockburn and near Kewdale of 40kph in the northerly direction as you put it for a couple of years now. This is due to the deteriation of the timber sleepers. They are due for replacement but in the wonderful world of privatisation of the rail infrastructure, the funds aren't becoming available as quickly as they probably should.

South bound trains are rushing to get to their destination in time for loading or unloading and in a lot of cases the northbound train is being regulated in time & speed by the crew to ensure arrival at the depots is not too soon for the crew to be issued another job (like shed work or car cleaning) but suitably timed to still knock off early Of course other traffic in the flow will also have an effect to some travel speeds.

Haha that's one way to put it lol

I've been wondering this for a while now.  Saw a CBH train putting along  some time ago and had more than enough time to wind around various back roads to get in front to see what loco was on it.  I didn't realise that the speed restriction has been in place for ages though.

I thought they just did that on suburban trains

well I guess if the 30 secs of slack in the timetable is a gain then you may be right.
