Apologies, but I'm trying to understand why you think the capacity is not sufficient with the current 2 vehicle trains.
Line 5 capacity models clearly state that the highest capacity required is around 5,500 pphpd at 2031.
Yeah, my suggestion is that I think the model is wrong. And yes, to some degree thats motivated from experiences with another project built for similar capacity where there was repeated insistence from politicians to cut the capacity of the line, and then ridership has exceeded expectations - a bad situation!
There isn't any reason to suspect that this number is incorrect. 5,500 is also almost triple what the current 34 bus carries on Eglinton. In any case theoretical maximum capacity with the current 2 car trains is around 10,000 pphpd, almost double the expected demand.
I don't agree that there is no reason, there are plenty of reasons! Of course the validity of those is something we will have to wait out to see.
I've said it before in the thread but, the ridership of one (there are a number of bus routes on Eglinton) route is only an indicator of ridership potential. You would hope that rail, faster service, higher frequency, and improved reliability would all act to drive up ridership. Including getting people who are taking other buses, or driving to switch to L5 - we have obviously seen this happen in city after city in the past - its a big part of why we invest in rapid transit.
That is the maximum capacity with two car trains yes, I don't think we have enough LRVs to operate that service level though.
The easiest comparison is the eastern portion of Line 2. Line 2 has a theoretical maximum of around 23,000 pphpd and is close to hitting this maximum during the morning rush. Line 2 has been operating for over 50 years with all the N-S feeder buses dropping passengers at it's station and yet not as busy as the Yonge side of Line 1. Are you under the impression that Line 5 will be similar to this shortly after opening?
L5 won't be similar no, but if it was even a third of the demand things would be crowded! Thats my point. Also L2 has had downward pressure on ridership for a very long time because of congestion at Bloor Yonge etc.
You mention Canada Line being under estimated on usage, but do you have any Toronto based rapid transit projects with under estimated demand? Sheppard Subway, TYSSE, etc?
The best case I have is looking at ridership *estimates* for other projects particularly GO and subway which have always had rather low projected riderships - I assume Metrolinx is overly conservative in their estimates. The other projects you mention are both essentially suburban extensions which have low ridership for various reasons, but which I don't think are comparable to a new crosstown line with numerous rapid transit connections and already lots of dense development.
Theres also the fact that we thought a subway was a sensible thing to build on Eglinton decades ago, before much of the density we have today was built / on the table.
I mention Canada line both because of the similar design capacity, but also because knowing the corridors, Eglinton is denser, more urban and has more feeder buses, it isn't radial which is probably worth something, but the Canada line has lots of demand outside of going to downtown Vancouver.
You're right, I mis-typed when I said the 34 bus has a capacity of 2,000 pphpd. According to the EA for the Crosstown from 2011, the maximum capacity for mixed traffic bus operation is 2,000. Meaning even in the areas of Eglinton East where there are multiple buses, the theoretical maximum is 2,000 pphpd. And that itself is pushing it as it'll be a bus every 1.5 minutes with 50 passengers per bus!
Yeah that number I would question, I've seen significantly higher numbers used to estimate peak hour bus capacity, 2000 might be for one line but I can think of lots of cases where its much much higher.
Yeah I question the validity of the numbers in the EA. Again they are from a time when Toronto was not growing like it has in the last decade. But also being familiar with ridership numbers for all kinds of lines and systems around the world they feel very low. 5,400 ppdph is not high for a line like this! Most other "rapid transit" lines in Canada carry significantly more people in peak hour - including in smaller cities like Calgary and Ottawa.
My issues is that I hear a lot of speculation when saying that the expected 5,400 pphpd number is under-estimated and that the line is going to be at capacity very fast, but I don't see any actual evidence of that actually being the case. Has the City or TTC or Metrolinx updated their expected demand numbers?
I believe so, this was why planned service level was increased over the base case.
From the datasheet for the Flexity Freedom:

It doesn't inspire confidence that the pictures don't show the vehicle we got!
And then there's the option of adding a 3rd vehicle to each train to increase capacity to very solid 14,400 at the same 2:30 interval. Granted, this might also need the City and the TTC to actually implement signal priority for Line 5. But if we're getting to that situation I think there is a lot of incentive for them to make that decision. Even now the strategy is that trains that are running behind schedule will be able to utilize transit signal priority.
14,400 or 15,000 is not that much! Certainly for a rapid transit line. As you mentioned L2 is far above that despite not having all that much density along most of the corridor, so is something like the Millennium line which is also essentially a crosstown!
My final point is that when we're getting close to the end of life of these LRVs, we should be looking at procuring slightly wider LRVs and looking to create gangways between the 3 cars to further increase capacity (like the TR vs the T1 subway trains).
Whether you can fit wider LRVs is TBD, I would suggest thats unlikely, unless you're going to be shaving back platforms (they are already not super wide from what I can tell) and relocating other infrastructure. You might be able to get trains with a slight barrel as opposed to box cross section.
I guess we're all going to have to wait for the line to open and run for a year or so before we can actually see what the actual real-world demand is going to be.
For sure. And I am certainly biased towards busier because I want people to use transit and I want the system to be as successful as possible! We will see!
