A friend of mine designed and worked on the original Calder Park Drive. So I’ve seen plans as to what it’s final form was meant to look like. This included a track to Watergardens and an entrance on the Down end to allow empty cars from Sunbury to run straight in. That was many years ago however.
A morning trip past the work site;
Three new roads are now visible, with a few high rail vehicles around looking as if wires were soon to be strung. The length is the same as the current roads, storage for an additional 6 HCMTs. There is earth works occurring beyond the new roads, I’m not sure if this if for another set of additional roads or Light Maintenance/Train Wash Facility.
A couple of new turn outs have been installed in the mainline, sans blades. Foundations and track bed are now in place from Calder Park down to the Substation. The track bed abruptly ends here. The retaining wall is sortcreted, for the track to continue this would need to be jack hammered away with a new retaining wall built. As you mentioned I can still see the tops of earth movers working away on something behind the Substation.
Down towards Melton Highway, foundations are now in place from Melton Highway overpass through the worksite, over the new bridge to approximately Chandos Street. Once again the formation ends here, with no work occurring between Chandos Street and Calder Park LX.
New foundations have been installed along side the up track suggesting this will be slewed on to the future alignment. Service proving works are occurring between the up track and Sydenham Road. No works are happening at the end of the current stabling to indicate this is being modified at all.
It is possible that they want to commission new roads at Calder Park to allow for storage before Watergardens is booked out for works.
Cable installation and foundations continue to be installed along the line from Watergardens to Footscray. The steel frame for the new control centre is now complete at Sunshine.
The Hobsons Road worksite is being demobilised now that tunnelling works are complete. Earth works and concreting continue on the approach ramp to the new tunnels.
About a dozen or so John Holand High Vis types poking around in cabinets and pits, pointing to plans laid out on bonnets this morning at Gap Road LX in Sunbury.
The jigsaw puzzle continues.
