It is 2019. There are two years of construction left according to the experience in this room and Metrolinx too.
The ION system in Waterloo has been running tests for a year to ensure vehicles clear posts, gates go down and signals work. A year in and no date for revenue service.
What does the TTC know that Waterloo region does not because I see no time for testing here.
Well, for one it's an apples-and-oranges comparison.
The signalling system for the Crosstown will be a greenfield installation, meaning that there was nothing there before it. It makes the installation and testing process much easier, as you aren't going around chasing gremlins which may be caused by older systems still in place and active.
The equipment for ION has been installed on an active rail line, meaning that they've needed a lot of testing to ensure that it is working properly regardless of the vehicle that were running on the line.
And then there's the fact that the Region of Waterloo postponed the awarding of the tender for the on-board equipment installation until last year, and the installation has not gone nearly as smoothly as envisioned. The Crosstown signalling system contract has already long been awarded, and even if the installation and testing takes longer than they figured, they've still got lots of time at this point to figure things out. (Obviously, this will change as we get closer to opening, and especially if portions of the line aren't completed by their scheduled timeline.)
Even the Spadina extension ran non-revenue service - if I recall for 3 months - September to December before revenue service.
1 board period - 6 weeks. That is Standard Operating Procedure for the TTC and subway openings. There was lots and lots of testing prior to that, however.
Let’s check this.
Rocket train - known vehicle. Flexity - new vehicle.
The Toronto Rockets were not a known vehicle when it was first delivered, and required a year of interface testing before it was cleared for revenue service. And if you're referring to the ATC/ATO signalling system on the TYSSE, there was months of signalling systems testing and integration that was done with both the vehicles and the extension independant of each other before that final board period.
Yes, the Flexity Freedoms are a new vehicle, which is why the first ones are being delivered now - almost(-ish?) three years prior to the opening of the line.
Controlled underground ROW with no competing traffic - no mixed opaeration vs underground and above ground Agni h the TTC has no experience with.
Except that the TTC has experience with both of those modes in isolation of each other. And they also have experience now with ATO-to-manual control migration points as well, and have for a very long time.
I would love to see this on time, but someone says there is barely a hole in the ground at Mount Pleasant let alone a station. Add in the time to test and I don’t understand how this can be done.
I too am concerned about the timeline of the project, but seeing as how it is still almost three years away from seeing any revenue passengers, I don't think that it's quite yet time to start sweating about it. If we're still having this same discussion in a year's time, well, then its a different story.
