Lots of work has been taking place between Caulfield - Richmond this weekend. While I didn't get to see some of it, I saw enough indirectly. Massive overhead stanchions were being built near the Glenferrie Rd Bridge in the old Malvern Sidings area. I had been curious for some weeks about the foundations that had been built opposite each other - then noticed this week that overhead structures were being installed on them. Along with a heavy-lift Metcalf Crane that had been parked next to the line. On Friday I spotted workers fitting isolators to some very big spans that I assume were lifted into place on the weekend (I'll know when I take the train to work tomorrow). My assumption is that a new substation is going to be built in the sidings area near the current tramway substation. There's two of these spans being installed.
Further along the line near the Kooyong Rd bridge in Armadale, two additional blocky foundations had been built on the Frankston line side of the corridor. I'm also curious as to what these are as they have circular bolts sticking out of them. There has been no work to build foundations on the brickwork side of the cutting as far as I can tell. I'm guessing that numerous other stanchions were installed up and down the line on both sides over the weekend. No new wiring as yet.
I also spotted work taking place at Richmond with new overhead foundations being dug although it was a bit difficult to tell exactly what they were doing - I was in a Burnley group line train at the time. Great to see this work happening.
On a side note, work seems to be ramping up near South Yarra for the Metro Tunnel entrance that is going to be built there. I've read on the Metro Tunnel website pages that work is gearing up for a major shutdown over the January break so that major work can commence in the location including demolishing the William St bridge, demising a brick retaining wall on the south side near Chapel St, and staring to widen the corridor to handle six tracks and the decline structure.
Edited to include some tweets from @trainspotter67 who took pictures of the new spans at Malvern - they are very big!
