Exactly. The added costs of having a bus loop is pretty high. Then forever we'll have buses turning left into oncoming traffic to enter the loop, which can be a dicey manoeuvre and may raise insurance costs. I wouldn't even advise pedestrian tunnels. Just a portal kitty corner from one another...

You should post the same sentiment in the YNSE thread. Like a dozen people managed to move a deep line that goes under a river into a line that goes much much more deeper. And they were briefed during the whole process lol. There definitely is a cost to using two future rail lines coming into...

I'm sure there will be a drain and troughed conduit. But everything else within that bottom third may just be poured concrete right up to track level. Or the track will be elevated using pillars with a sizable void along either side? I'm curious.

TBM is so big, once it's done you could place it permanently somewhere and turn it into a condo. So my question with a TBM this large is, once finished the tracks would sit roughly in the centre of the tunnel. What do they use to fill the space between the bottom of the tunnel liner and the...

Wouldn't the shorter car end up heavier then, since like you pointed out has more wheel to weight ratio. Also third rail doesn't need a transformer on board, further reducing weight. Seems more efficient. I'm still a third rail supporter. Costs are lower, tunnels are more realistically sized...

No it's one. That's what threw me off. Existing bridge is really two bridges over two streets. This new one at first glance is a simple expansion off these..Makes sense. However since it has to carry over the whole intersection it's really its own separate, single bridge with no central support...

Hold on a sec. Weren't you arguing that lines like Crosstown should be like Calgary - with a central surface street-running portion in the highestest-density area? Also where the lanes are most reduced, pedestrian volumes are the highest, intersections are very close together. How well would...

I guess I was more wondering if there's a slightly more 'modern' take on a truss design. Tho perhaps such a thing would no longer be truss, and may not really exist. I like corten in certain instances. Not so much in what you're showing. Just looks like rusty old bridge. So with this Gerrard...

Hopefully you're right. Would love to see a truss bridge. Would it look like that if it was built, or is there a more modern take on such a design?

The Gerrard station is something. Enveloping the station in a humongous faux 19th truss bridge avec massive pre-rusted iron girders..? I'm pretty sure these are very rough concept renders. Obviously look nice since it's 2022 and computer animations have come a long way. But I wouldn't hold my...

Thumb on the scale is something I'm sure we've seen before. But since it was a Metrolinx study in favour of Doug's subway, I don't think it's the case (unless the thumb boosted the subway numbers more than otherwise). Recurring thought I've had, and it's a bit of a paradox, is this: The LRT...

It's a bit contradictory though because you're saying it should have a supplementary bus service for in-between stops, but also that a metro line will carry more. This was modeled for Crosstown West. The in-median line with more stops beats the grade-separated line with fewer stops in terms of...

Wouldn't they go with all grey trains then? These are basically black and white, with a strip of grey. Kinda seems like it's to match their logo, which is also black and white. Their old logo was two tone green, would've been nice to match that.

No I mean the suburban stretches of Eglinton. With population densities rivalling those of downtown Edmonton and Calgary - the very places you say tram LRT makes sense. data from CensusMapper.ca

This is a bit out the window though because even as a suburban arterial, the densities along Eglinton are relatively comparable to the downtowns of Edmonton and Calgary. I was a hard advocate of building a light metro line across Eglinton, but doesn't mean I'm not afraid to face facts about the...

I think TSP will work ok. Seems like all the surface vehicles in the city have a green-hold system. Can't force a red, but want to make the green while people are boarding is doable as is evident. What nobody brings up in all this is the likelihood of future midblock traffic lights. As blocks...

With a high-floor metro vehicle I think it's safe to say there'd be a slight uptick in speed and experience relative to a low-floor LRV. It would have better acceleration and more optimal internal layout. Also there would be cost savings since the stations for a separate line wouldn't by default...

And at the end of the day this "subway" is still very much LRT. Just an unbelievably expensive one, with fewer riders than the previous proposal, and still not reaching the airport. I actually interpreted @M II A II R II K's post to mean terminate Crosstown at Mount Dennis, and use OL...

Are there any Infiltrators any more? Has anyone gone down into these u/c tunnels and taken some cool pics? I know these types of things shouldn't be advocated *wink wink*. But I'm advocating it lol. They're deep, they're massive, once complete they'll be almost impossible to access. So let's...

Building something to 400-series standards is a pretty big deal. You write "mostly rural" and there's an implication it's a low-speed leisure road winding through the trees. It's not. It's an extremely massive engineering task, insanely wide tract for max expansion, carves down any landforms to...
