Work commenced yesterday on the major upgrade of overheads and signalling systems around the Caulfield Junction area. The crews seem to be working 24/7, and there is a multitude of equipment being used. Yesterday was mainly about removing wires from midway between Caulfield - Malvern through Caulfield station and a bit beyond. Also, they installed the remaining new wires on the inner tracks from Malvern to the next changeover point just before Tooronga Rd.
Today was much more involved and you can already see the progress around Caulfield. The new stanchions are sporting new wires and although they weren't tensioned yet, I'm sure it's only a matter of time until they are. There is also some other work taking place at the end of platforms although I can't tell what the crews are up to - could be something to do with the new platform extensions. Further back up the line this afternoon, the old stanchions were being dismantled. This involves three cranes to hold the pieces up while they are unbolted (or cut), then they are lowered to the rail level and cut up some more. The pieces are then transported to a site near Malvern station where they are being stockpiled for eventual removal. This work is continuing overnight so I expect by the morning all the old stanchions in a certain section will have been removed leaving the new stanchions. Around Malvern there's some work taking place next to platform 3 at the city end. Again i can't tell what's being built but some concrete is about to be poured there. I also can't tell what's happening up the line for obvious reasons - unless I choose to travel to those locations. I'm sure with such a big shutdown there's other work taking place.
Anyway, I'll be watching the works with a keen interest although I'm going interstate for the weekend so I'll miss a bit. Perhaps other posters can fill in more details.
