Works for me. Nice pictures. But I'm not going to start reading yet another forum ...

I stopped posting to Urban Toronto a month or so ago. I enjoyed giving them updates on our little project over here, but left when they decided to gang up on me when I started posting to their (self-started) Monorail proposal thread. Bunch of hotheads over there on that one. Glad we have a nice little friendly community over here - much like the city itself.

Looking forward to seeing the progress at Waterloo Park - I've been out of town for several days, so I missed seeing the final product come together! I assume the old, temporary track is still being re-used and no CWR has gone down?

Here's some photos I took yesterday afternoon.

Thanks for sharing! Seeing the old track (wooden ties and short sections joined with fish plates) confirms my theory that they will do the whole run of Continuously Welded Rail in one long shot. So once they start, they will just do the whole thing all at once in one long process. Makes sense, really - bring in your experts on that just once for one period of time and get it all done. So all the prep work of the ballast and underground upgrades is just to prep the upper layers.

Works for me too, but not page 35.  Strange page 34 and 36 works, but page 35 not found.

Any guesses on the purpose of the smaller, round culverts to the sides of the main passages?

Those are for the kayak paths.

Likely overflow for the extreme rainfall that comes every now and again. Or for the ducks.

My guess is for wildlife, but it is just that: a wild guess.

[Canard]

I vote ducks. This was my thought too.

It could actually be drainage holes from the ballast for the tracks above. There will be a poured concrete edge to hold the ballast in place, so the water that seeps through when it rains has to go somewhere.

The Charles/Ontario intersection looks to have all its underground work done, I won't be surprised if it reopens early next week.

Looks like I have to eat my words; there's a new large hole taking up the south half of the intersection now.

Maybe storm drainage from storm drains in the large yard at the Barrel Yards?

No. They just run through the embankment parallel to the large culverts with no junctions or bends.

The culverts had no visible openings other than at the ends, so I don’t think they will be accepting water other than from the ends.

The only thing I can think of is that the math says that the three large culverts aren’t big enough, but the next size up would be excessively large and the two small culverts are the cheapest way of meeting the capacity specification. But I don’t actually know.
