^ Where is the Train man Walkway portion of the bridge? I can't picture it.
They say: "Work will involve demolition and reconstruction of a new rail-side trainman walkway on the south side of the bridge. " I assume it is at the edge and was/is to allow train crews to walk safely off the tracks - we need an aerial photo!

Platform closures will finally end on October 30 (for now, at least)

Starting Wednesday, October 30, some Lakeshore West, Kitchener, Stouffville and Lakeshore East weekday afternoon rush-hour trips will depart from different platforms now that we're done enhancing safety and communication features at Union Station.

We've added new tactile yellow tile and installing infrastructure for brighter platform lighting, new electronic signage and PA systems. This fall you’ll begin to see these new features up and running in the train shed.

Updates from the email newsletter on state of good repair work, the 81 Bay Street "overbuild", and the Yonge Street bridge work (noted above).

Regular Maintenance (state of good repair)

Work crews will be on Track 8, just east of Union Station replacing rail ties on Friday, October 18 from 8:00pm to 5:00am. As well, work crews will be replacing rail ties on Track E5 between Parliament and Cherry streets on Saturday, October 19, from 8:00pm to 5:00pm. This work may at times be very noisy with the use of heavy machinery and work vehicles.

Ongoing work - 81 Bay Overbuild

Work crews associated with the Hines CIBC 81 Bay Overbuild construction project are presently installing steel beams and columns to support the new pavilion that will eventually house several new restaurants within this new complex. The work is performed overnight, and although every attempt is taken to address levels of noise, work will be disturbing to some. Please note this work will continue for at least another 3 1/2 weeks, into November. [more text below this big picture]

Blog post on the latest:


This is interesting:

A concrete extension is shown jutting out from a Union Station platform, as a GO train arrives.

New platform extensions have been added to Union Station for future use. (Scott Money photo)

And here’s an interesting detail customers can, while pointing out their train windows, share with fellow travellers. Metrolinx is extending some of the platforms by installing new concrete curbs and asphalt surfacing outside of the train-shed for future service needs.

A platform extension is shown on a Union Station platform, at ground level.

The extensions, for future use, are shown at customer level. (Scott Money photo)

You can see these extensions as they push out from beyond the normal ends.

One those screens are lit up (and the temporary lighting transfers to the new permanent lighting built into those utilities ducts)...

...It finally look like proper 21st century old-station-retrofit infrastructure rather than a Happy New Year 1963 dated train station platform look.
That's more like it. The Bay Concourse was Happy New Year 1983.

^ Also, can it handle a 12 coach train or only a 10 coach train? cc @smallspy
These "platform extensions" are simply refurbishments of the existing exterior platforms on those tracks. Nothing more than the usual Metrolinx spin.

For the record, the longest platform - between tracks 8 and 9 - is about 2800 feet long, which is longer than 3 L10s. The next-longest is the baggage platform between 7 and 8, and it's a little shy of 2600 feet.

Double berthing is mentioned in the old Metrolinx 2031 document as a capacity improvement. I think I also saw that phrase in the 2015 RER Business Case (the multi hundred page PDF).

Theoretical use cases (not all necessarily applicable)
- Opposite direction trains (Milton versus Richmond Hill). Like two dead ends.
- Backup berth if part of platform is closed
- Live staging option (pre-berthing a peak train) to enable 24 coach preboarding for one route w/staggered departure
- Flex for two bunched trains, to reduce need for last-minute platform switch
- Less disruptive berth option for unexpectedly out-of-service train
- VIA Canadian 😀
- Etc.

Signalling needs to be added to activate simultaneous double berth (like at UPX + Platform 3).

Not saying ALL of this will happen, they are just theoretical use cases.
