Some of the upgrades are to power systems.
I’m not normally one to write blog posts about new items of infrastructure, but have you seen these bad boys installed near Armadale station?
Not your average overhead wire stanchions.
There are two of them. It appears they’ve been used because there’s a lack of space on the north side of the rail lines just east of Kooyong Road.

Apparently the distinctive spiral design is to keep the structure stable in the wind.
They’re quite impressive. Keep a lookout if you’re going past.
And expect to see similar power upgrades on the Sunbury line in the coming years to prepare for trains to be through-routed from Cranbourne/Pakenham via the metro tunnel out to Sunbury.
- There’s a whole Reddit thread about these.
