Light Rail Stage 1 Construction
« on: November 14, 2017, 06:35:34 PM »
It is rather difficult to observe construction of Light Rail stage 1, due to its location in the middle of busy roads with activity mostly remote from easy pedestrian access. The most convenient viewpoint I have found is from the high rear seats of a route 200 bus, but this certainly doesn't allow for much photography or watching of activity.

One opportunity I happened on, was viewing the concrete track extrusion machine in action adjacent to an accessible car park next to Hibberson St on City side of Hinder St. Fascinating to see how quickly it advanced leaving behind fully formed concrete track complete with slots for installation of rails. Presumably there was laser guidance to keep the work accurate. Never-the-less there were some half dozen workers with trowels, etc touching up the surfaces and ensuring the slots were clear. Counting both directions, the mind boggles at the thought of some 24km of touching up by hand.

So far most above ground activity and effort seems to be in Flemington Rd with noticeably less obvious day to day action in Northbourne Ave.. The range of machinery in use and the sheer volume of work entailed is amazing. And not just machinery, when viewed from the bus, there are often many workers on foot, kneeling, etc doing detailed stuff. No wonder the cost is high.

Noticed today is that some 'overhead' support poles have been installed, and part of the depot entrance track including points and crossing work is in place.

The appearance of 'overhead' supports seems to confirm that, despite being on the cusp of self contained power supply and the apparent adequate daily battery life of bus710, that abandonment of 'overhead' power supply in favour of batteries is not yet a reliable viable option in the eyes of Capital Light Rail/Transport Canberra.

Don't forget all the lanes inside the depot - that would add to length of manual touch up work.

From what I can tell, not all of the track will be laid using the track machine. At points (such as outside the depot), the tracks will be laid onto a concrete bed and then back-filled with concrete.
