I saved the best for last: the crossover at Conestoga! I just love all the fixture work for securing this very complex piece of special trackwork.

Showing the new 6-lamp crossing lights - the two lamps facing the tracks are white, and indicate to train operators that the signal is in fact activated (they flash at the same time as the two red ones facing those wishing to cross).
Hostile is exactly the word to use. You are not the only one to feel this way.

Are these signals and lights and barriers only necessary because the line carries heavy freight rail or is it some other law? i.e. if it were a dedicated LRT right of way with no other train traffic would the same precautions be taken?
Everyone move to the back of the bus and we all get home faster.

This was my thought, but as was pointed out to me, similar barriers and fences are in place along the Hydro Corridor which carries no freight.

Canard, some of those pics look like the rails turn down William St E!

There is a 65km/h speed along that stretch and electric trains are kinda quiet so that's probably part of the reason that they have those gates. Is there an off-the-shelf solution besides these kinds of gates?

Lost-esque sonic barriers?

So here's what I don't get. if this new issue has nothing to do with the grounding of the rebar, why are they removing concrete so far back? Can't they just bring in a cutter and shave off those few errant millimetres?

I think most of the hostility comes form the fencing. If they were
A) not grey chianlink fences, or at least covered by some shrubs / trees, and
B) didn't have the 2 perpendicular pieces and the opening that look like they are "funnelling" people though,
it would look a lot nicer.

On the other edge of the park there is a similar ROW that carries traffic often moving at 65 km/h and sometimes no noisier than the LRT. It's called a road.
It has everything to do with the general railway regulations and nothing to do with the specific conditions and needs of this particular installation.

I agree for the most part, the chain link fences, and the "funnels" are quite hostile looking. But I don't think much of the gates either. They aren't quite as hostile, but are still out of place. On a pedestrian ROW there is no need for giant lights and bells, with an enormous car sized gate arm. Something pedestrian sized would function the same (or even better as the lights would be at eye level) and look far better IMO.

If it was too close, maybe - though you can't really cut the concrete accurately and keep a smooth surface. And some of the edge may be too far away. They have to cut back to the rebar so the new concrete bonds properly, otherwise it would just fall off. The tolerance is 1400 +5/-0 mm from track CL to platform edge, which is very tight for "bridge building" techniques.

To your knowledge Canard, how susceptible to heaving in northern climates are these tolerances.

Since the embedded track slab and platform are touching/one body, once it's together I don't imagine there will be any issue. The nominal gap will be 75 mm between the platform edge and the wear strip on the train, so even though they're doing all this rework it's not like a train would have crashed or scraped on its way in - they weren't out that much.

That 12 km/h limit is quite an interesting quirk!
What's more concerning to me though is the 35 km/h signs past that and then the 30 km/h sign in the background. I suppose those limits are there to take into account the curve in the road and the resulting track geometry, but that seems very slow. The rest of the traffic along that stretch of King will be going 50 km/h (or at least that was the limit pre-construction, haven't driven there since then so don't know if it's changed), but the LRVs will be plodding along 15-20 km/h slower. How will we encourage people to leave their cars at home and try out our new system when it will appear so much quicker to drive? I realize that in the grand scheme of a journey a 15-20 km/h difference isn't that huge, but perceptions are such an important part of encouraging transit use.
The 25 km/h stretch along Charles between Manulife and Victoria is another one that seems unreasonably slow.
