Overhead referbishment?

 
  L1150 Assistant Commissioner

Location: Pakenham Vic.
In addition to the level crossing removal works I've noticed, on the Pakenham line, that new footings for the overhead support stanchions have been cast almost all the way out to Pakenham, not just at the works sites. In all the publicity floating around about improvements to the metro system, I cant recall anything about overhead refurbishment. Does anyone here know more about this?
Thanks L1150:D

Yes I think I can enlighten you.

The overhead refurbishments are part of a whole line upgrade project from Pakenham/Cranbourne to the City in preparation for the HCMT's (High-Capacity Metro Trains). This refurbishment encompasses the skyrail project and is being delivered by LXRA. In addition there is going to be a signalling upgrade and probably track upgrades as well.  There was an entry in the October LXRA community newsletter for the Skyral (CD9) project about the commencement of the whole line upgrade: http://levelcrossings.vic.gov.au/media-library/publications/caulfield-to-dandenong-publications/project-wide-community-updates/caulfield-to-dandenong-community-update-october-2016

Re the new overhead footings, these have also appeared in the Springvale - Sandown Park area, Oakleigh - Clayton & Caulfield - Malvern with some indications they will be extending them all the way to the City.  I have been told that every overhead gantry will be replaced - most of them are near 100 years old anyway so they are due for replacement.  Large work bases have been established at Dandenong & in the old Malvern sidings area for this part of the project.  I can't be sure but there is new construction happening in the old Malvern sidings between the Tramway substation & Glenferrie Rd - a large area has been paved with gravel, a short section of signalling conduit has appeared at the back of this area, and a shipping container has appeared - new signalling relay room?

Anyway, with all this construction going on, the whole line upgrade, CD9 removals and soon Melbourne Metro junction at South Yarra, it's going to be a very busy line for construction over a number of years.

The OHW in Sydney is being renewed to a different and improved design. This might help explain OHW changes that might be taking place in Melbourne.

Something to do with your weather...?

Melbourne went through a phase in the late 80's/early 90's where lots of old overhead gantries remained, but new attachments were added - it created a bit of a wish-mash but it worked. However, that still left lots of ageing gantries.  Now it looks like the imminent addition of new trains has meant that large scale infrastructure upgrades are needed, not that that's a bad thing, we desperately need more investment here. Having a whole line upgrade of nearly 60km hasn't happened before. It will be interesting over the next few years to see what will be improved.

As for Sydney, I was there a couple of weeks ago for a rare visit. I've seen that they have been rapidly improving their overhead power networks for quite a number of years now.
