GO Transit: Construction Projects (Metrolinx, various)

You_Doodle+_2025-11-23T21_36_52Z.jpeg


I’ve always wanted a proper visualisation of what this section would look like when it’s fully built out, but Metrolinx has never released renderings like that.

it’s not the best I tried to do it myself:

Yes. The current plan (30%) is to the east of the Credit River.
Makes sense to me. I think that's why the two northern parcels were acquired. Only a small piece of the southern parcel is adjacent to the tracks. The 2015 reference I'm sure is just the general vicinity. Images posted again below as they are now back a few pages.

Also, amazing to hear it's now at 30%. That's the first specific update we've heard since the Leave to Appeal for the OLT decision for the expropriation was settled with the property owner out of court.

I think this means there's no need for a 2nd platform at Georgetown GO. Hourly trains can pass on the 2-track grade separation, and at Acton, Guelph, & Shantz. Roughly equal distances apart.
But there'll be no "slack" in the system, one late train will disrupt the service.

This is epic!! After all the crooked line MS paint style drawings we've all done in here in anticipation 😅

Well that resolves a lot of confusion I had about the map. The terrain west of Georgetown is tricky, and with all the land secured east of the river, things weren't adding up.

Other things I note:
  • Station upgrades for Georgetown GO aren't noted. I'd like to chalk that up to the disclaimer "not all projects are shown", but they also highlight a new signal and pedestrian crossing, and make Innisfil two bubbles...
  • Woodbine is confirmed again as being a joint UPX stop. 5 intermediate stops on on express train 😠
  • "3 tracks Strachan to Bloor" I presume means filling out 4 Kitchener / UPX + 2 Barrie + 1 Milton through the Strachan trench to past Parkdale
  • What's being improved with the Bathurst Interlocking?
  • Electrification only to Pearson is certainly a climbdown, but wondering if the newly negotiated CN agreement for Halton is a factor (trackwork is bigger fish to fry)
 
Note: PDF page 1,159 notes there was a reduction in the Heritage Road Layover design from the 2015 image noted above:

A contact of mine who works in municipal government out that way and was involved in the planning for this facility has kept me entertained for years with anecdotes from this project, depicting it as metrolinx project planning at its worst: multiple iterations and designs with little rationale as to why the last design was torn up and rethought; endless meetings populated by contingents of ml staffers from different departments with diffused accountability who had never compared notes or reached a common position beforehand, consultants with airy ideas who had to have basic concepts of how railroads work or practical considerations affecting siting a rail yard explained to them.

Happily, something is now being built.

I do wonder about some of the planned capacities cited. At 15 minute headways, an 8 train yard amounts to feeding two hours' worth of trains towards Toronto in a service model that assumes trains coming the other way and turning back. I'd sure love to know the rationale for those earlier versions.

What makes you think that the noise disappears with electrification?

It doesn't. I'm familiar with the "wooshing" sound a lot of these higher speed, electric trains make as they fly by.

Just wondering why in England, people will live right beside a busy mainline, and the noise from the trains passing by doesn't seem to bother them. But here in Ontario we have to erect massive, sun blocking, noise walls inorder to appease the folks who live right beside the tracks.

A lot of the merit of those walls is security and not just noise abatement. And to be clear, in the UK (and elsewhere) , it's not uncommon to ride for miles staring out at a high embankment or stonework or vine-covered fencing. Sure the stonework is 100+ years old, so it looks nicer, but it's not there for passenger enjoyment.

Hopefully with time the ML noise walls will at least be covered with vegetation and that will end the tagging blight (my standing offer of providing shoots from the stuff in my garden that I am unable to fully remove still stands!) Yeah, the walls are a lot less charming than the old view - pretty close to riding the subway in spots - but they serve a purpose. Our grandchildren will be glad they are there.

For hourly service you need passing tracks precisely 30 minutes apart. Currently the travel time is 29 minutes from Guelph to Georgetown so for the grade separation to work as a passing location the travel time would need to be reduced by about 5 minutes between Guelph and the grade separation. They can definitely save a few minutes by resolving the yard slow zone in Georgetown but that still leaves another couple minutes to be found.

As has been pointed out further up this thread, in England the trains have been running there for many, many years at similar frequencies. Where they are improving the frequencies they are only increasing incrementally. But don't kid yourself either, there are numerous places where they have greatly increased the services on the lines and have put up massive sound walls. Look up the works for Thameslink and the Elizabeth line, for instance.

In most cases here, the planned frequencies are exponentially higher than they were when the people moved in.
