GO Transit: Construction Projects (Metrolinx, various)

[Sauga89]

Metrolinx has released a diagram to explain how it develops work plans. Basically, I think it's a diagram which shows how projects are expected to be developed and managed. It's a bit big for one screenshot, so you have to follow the link to zoom in on individual bubbles.

The east tunnel for Long Branch is now trap with a tent above it and most likely been waterproof before been pushed under the tracks. Have seen no work on the station platforms in months.

As to the comment of only having side platforms with two express tracks, i had a better look at the south side today with all the greenery missing. There is some room for a side platform, but will require rooming a few 100 or so trees in the ROW as well the backyards of homes backing onto the corridor. At the same time, those homes will loose some of their backyard to build a retaining wall for a wider platform that will be backfill once the wall is built.

The northside needs a retaining all the way to Etobicoke Creek alone with a new pier support. The pathway will have to be shifted to the north to deal with the retaining wall. The current track 1 platform is haft of a centre platform being built that can become a full centre platform at a later date.

More up on my site
All the new bridges are in place for all 3 tracks at Long Branch over Etobicoke Creek. They have struct bracing at each ends.

This will make some folks happy, there are rebar coming out of the centre pier most likely to extended it north to support the new future track 1 bridge,

From what I could see, post were added to support the double track deck truss bridge that was removed to support the four all four girders box, They look the same as track 3 bridge as they are the same depth.

So it's been future proofed for a possible fourth track?

I hope Santa delivers a West Highland Creek culvert this morning.

Bit confused what you mean here, I thought a supposed 4th track would be on the north side, not south side. The side platform comment was just to swap the south config from currently PTTPT to PTTTP, which i dont think should be any wider? If anything, I feel side platforms should be thinner because you dont need setbacks on both sides of the platform.

Its not the first time ML has built haft a platform than have the other haft sit empty over a decade or more when they have no idea when a new track will be in place for it. Have said that, one only has to look at Cooksville platform that was rebuilt as a centre platform some 5 years ago and will remain that way for many years until ML and CPKC can work out a deal to have 3-4 track for the Milton Line.. Can't recall off hand, but the Lisgar GO station built in 2007 is to be a centre platform that maybe a haft platform at this time or was built as full platform since they were building various section as three track corridor.at the time. There was also to be a side platform at the station side. That is 18 years ago.

Unless you want to rip up all the work for the new platforms for Long Branch as a PTTP at great cost, ML is most likely not willing to do it with egg on their face.

You still need space for a south platform as I noted above as there is no room to have another track south of track 3.
