seriously speaking, why is this taking so long? How long does it take to switch systems. theyve already had 5 years to figure out how to do it on the vaughan extension. I cant fathom why it would take 3 more years to get to finch.
You can build a whole line in 3 years! Its like theyre trickle working on this at the minimum amount of work possible.
 
New TTC report confirms completion date for installation of automatic train control signalling system (the work that necessitates frequent subway closures) has been delayed from 2019 to 2022, and budget has increased by $98M to new total of $661M. o_O

Because unlike the TYSSE, they have to install the new signal system while keeping the trains running, and the old signal system going, and all of the other systems that will interface with it such as power control, and all without interfering with anything.

It's an order of magnitude more difficult to install a system like that overtop of existing systems and not affecting them than it is to install in a naked tube with nothing in it.

How much of that would or would not be covered by a subway upload to the province?

In japan they managed to reconfigure an entire station to different grades overnight:

In China they built an entire station in 9 hours

Are they working at night at the moment? How many people are working on the tunnels when they have the chance to? How long does it actually take them to do each 1km? You can excuse their lack of determination and pace all you want but face it; work on any north american project is just plain inefficient. Were not even talking about Line 2! Theyve had 11(!!!!!!) years to do this and they still go at snails pace. The longer they drag it out the more expensive its going to be.

Then the question to ask is: how long would it have taken if given an uninterupted work window (i.e not keep the trains running)? If it's say 2-4 weeks, 24hr uninterupted, then maybe the answer would be to close the line for that amount of time. Obviously that would result in hell on the surface for commuters. But if done in August, would there have been benefit vs the rolling closures we're dealing with. Was this ever considered? Maybe such can be done when Line 2 is tackled.

I'm pretty sure if it was it was probably brought up as a non ideal option C to support the most preferred option A which is whats happening now. Honestly though it is very feasible to get this done in 1/2 of the claimed time or better.
Its just that they dont have any sizeable work force in the tunnels during the construction window; likely minimal numbers.

That type of closure was considered to fix the sinking track around Davisville. What they discovered is TTC doesn't have enough buses or drivers for that; they'd need to lease hundreds from 3rd parties to meet rush requirements (poorly). Using just TTC resources, they expected morning rush would run well into the afternoon.

Well don't forget about the labour laws in those.countries which are lax comparing to here. I kind of wanna here how many workers got injured in those 9 hrs
