I agree. One of the biggest issues with the TSP system on the streetcar network is that we have a very simplistic way of estimating travel time that is usually wrong, since it would be logistically impractical to separately calibrate a formula for each direction at each intersection at each time...

If the schedule were reduced by 10 minutes per direction (20 min round trip), here are what the headways would be with the existing number of vehicles in service at different times of day: 18 minutes saved round trip seems more likely since it produces a clockface 10-minute headway in the...

Yeah I showed it as doubled since it's a future map, there's enough space and there's discussion of a Bolton GO service that would presumably be tied to capacity expansion on the CPKC lines. I figure a Bolton GO train would have one side platform at Mount Dennis on the CPKC line, directly...

I guess you got false information, because that has never been factual. They have been primarily using Walk extensions ever since the TTC developed their first TSP system under the previous MTSS signal control system. It makes sense that you trusted the information you received from what you...

Okay, the last time I watched the TSP at King & Church was in 2019 so I guess they changed it since then. It was definitely extending in Walk then, not Solid Don't Walk. Maybe they changed it when streetcars started turning there, to clear out pedestrians to facilitate turns. When you change a...

Yes and no. At 6:28:06 in the October 27 Infrastructure Committee meeting, Councillor Saxe mentions that of the 440 intersections with TSP, about a quarter of them have TSP disabled. Of the ones that are actually on, most don't work well. But the reasons they don't work well vary by...

Black & Mac is the City's traffic signal contractor. They don't call the shots, they just do what Transportation Services tells them to do. It sounds like they were also hired by Mosaic during the design/construction stage, which makes sense since they're already familiar with Toronto's signals.

They have two detectors. A "check in" detector (that's the one just past Jarvis that I showed) and a "check-out" detector just past the stop line. Sometimes there are also intermediate detectors to update the streetcar's ETA as it approaches (e.g. WB St Clair & Gunns). The streetcars have radio...

If you only build side platforms you need 2 elevators per tunnel. One on each side of the corridor. If you build a centre platform as well, you need 3 elevators per tunnel. One on the north side / side platform, one for the island platform and one on the south side. If you add a 4th track on...

Yes and not proposing any plans (on any timescale) to extend the quad-track on their busiest line is short-sighted. Precisely because it results in situations like this, where they could have protected for a fourth track at minimal extra cost* and they just didn't. *A quad-track layout with...

I'm really struggling to see what the confusion is here. It's exactly like you said. 2 tracks for a subway and 2 tracks for GO. Why on earth would that mean that GO trains need to run non-stop from Malton?

Last I checked, the TSP at King & Church extends the Green/Walk for King streetcars before the start of the pedestrian countdown, then when the streetcar enters the intersection it starts the pedestrian countdown. This is specifically because it takes so long for streetcars to cross the...

This is a good question, though it's 64 coaches since you need to add 2 coaches to each of the 32 trainsets. I don't think Via's order cost was broken down into coaches and locomotives, but CalTrans' order for 137 coaches cost $371M USD in 2017. Which is $512M CAD in 2017, or $646M CAD in...

I'm not sure they would be able to sell it on a fully financial basis based on Via's own operating budget, but they could probably sell it if they take into account the public benefit of getting more people onto the rails and off the roads. The challenge there is that the associated financial...

No it wouldn't force the trains to go non stop. Nor did I ever suggest Kitchener trains would be running non-stop from Malton (or anywhere). I clearly showed Kitchener Line platforms in my diagram of Mount Dennis so clearly I'm not talking about all Kitchener line trains going non-stop. Why do...
