There is something noteworthy that Steve points out, a semi-permanent closure of the subway to install these will save a crapload of money.
Not just the 4 hours and weekend closures once a month.

Something skipped over in the recent Rogers installation report is the note that work crew schedules are pretty damn tight. there's currently not much room to add more work in.

What is the logic behind using a super busy station like Dundas as a prototype rather than testing out the technology on a station where a full scale closure would cause considerably less disruption, like, say, Chester?

I watched about 5 min of the board meeting and this happened to get asked lol. Here’s the exchange:

Thanks for this. I haven't see the track intrusion numbers per station but I suppose it's fair that they want to test on a station with high track intrusion to see how much effect it will have on operations in general.

If they close off sections of the subway to install this they need to implement consistent express shuttle busses between sections with ROW lanes.

It took them no time to do the same on Spadina when the busses were stuck in traffic.

I assume because they want a "worst-case" or highest traffic scenario to pilot on. If nobody uses Chester it's tough to say how they would handle large groups of people or crowd crushes.

I'd very much assume that is the case. I'd think the big question with these doors, is how they'll behave on very crowded platforms with people leaning against doors, and trying to go through doors as they are closing and properly opening. That's going to be a lot easier to test in places you regularly get such conditions. It's all fine if it works in a remote place ... but they can't start a system-wide installation until they've properly stress tested it.

Completely ridiculous that we're looking at a 20-year timeline for a system-wide implementation. We're talking about a 2050 completion for this.

I'd assume that's mostly funding. Though it's surely over a decade until there's system-wide ATC.

When they installed platform screen doors to existing lines in Busan, South Korea…they didn’t have to close subway stations to do it, and it maybe took a couple of years at most.

Busan's subway system opened in 1985. The TTC subway is about 30 years older and has much more asbestos in it.

If it was that easy, we would have started in the 2010s.

When I rode the Busan subway in the 1990s it was pretty tiny. Looks much larger now. Presumably the new stations were more likely to be door ready to begin with.

If you look at the station list in the TTC reports, any TTC station that's opened since 1985 has a lot less issues they have to deal with.

How are doors working on older system? I haven't seen ANY in Paris or in Manhattan. I've only seen it in London on brand new stations - and even on the Jubilee line, they didn't go back to the pre-1990s stations and do those.

Tokyo basically has them everywhere now, though not the full-height doors like the Elizabeth Line. Much of that system would be of similar vintage to the TTC, or older.

according to this there's a bunch of lines with them in Paris

Which means 2 of the biggest issues - lighting and ventilation - go away. And perhaps even the structural issues, depending on how much lighter they are.

How did their implementation impact service disruptions from suicides and other track intrusions?
