Thing is that there are almost no intercepting bus routes along Don Mills. the only riders along the corridor are using the Don Mills bus, and no riders would really be intercepted. Don Mills north of Eglinton is almost exclusively a local corridor, and would be just as well served by LRT as subway. The Don Mills LRT should interline with Eglinton anyway, as well as Jane. (instead of 1/2 the trains turning back, 1/2 would go up don mills)

But it's a another transfer. I want to avoid the crap with Kennedy. People will complain. On Google I see what you are talking about but still.

Hmm, what about running Sheppard to the Don Mills/Eglinton DRL terminus - then riders from Scarborough can arguably have only a one transfer ride to the core.

Bingo. That will work.

But they don't *have* to transfer, they would be able to run to eglinton on yonge if they wanted (and transfer there). Its still a single transfer to get downtown. no way is it worth spending $2-3 billion extra to run a subway that is completely empty. its completely practical, and the don Mills bus isn't even that busy north of Eglinton. (most of its ridership is from people in flemingdon park getting to the B-D line)

I hate to agree with andrew here, but you and I know that would work perfectly fine. I'm just worried about public perception. I think Don Mills to Finch would take pressure off the Yonge Line. Same the BD to Finch. Peel as many riders off as possible.

It's not uncommon transit users to change modes in a corridor. Yonge St for example. What's poor planning is thinking the only technology that matters is subway. It's largely why transit expansion in Toronto has been slow. The purpose of the DRL isn't to relieve a short congested section on the DVP.

The DVP between Eglinton and 401 (and the 404 southbound south of Finch) is congested practically all day, 7 days a week. It is not just a rush hour problem. This has got to be the single worst bottleneck on the Toronto highway system, caused because that section of the DVP is only 3 lanes each way wide (except 4 lanes between York Mills and 401) and 2 lanes on the bridge connecting 404 and DVP. In rush hour, the DVP/404 is pretty much gridlocked all the way from Stouffville Road to the Gardiner and it regularly takes 60-90 minutes to drive that section; the DVP/404 combination tends to have the worst travel times of any highway in the city. If you add in the fact that the Yonge line is severely overcrowded south of Finch, this means that a Don Mills subway line to Finch would get extremely high ridership, probably higher than any other proposed transit line in the GTA.

Putting LRT and subway on the same corridor is always a bad idea. The Sheppard LRT was only proposed because the eastern end of the Sheppard subway was cancelled due to Mike Harris cuts, and there was not enough money to extend it. No one would ever propose such an arrangement from scratch, we would choose one technology or the other for the entire corridor. There are always going to be bus-subway transfers in the system, but the difference is that a bus can easily be replaced with a subway extension while an LRT is almost impossible to get rid of (politically) when it gets severely overcrowded.

andrewpmk:

Just because a highway is highly saturated doesn't say anything about public transit route covering part of the way will be busy - they are likely serving fundamentally different destinations, and switching from LRT to subways won't be competitive from a travel time perspective - you really need regional rail for that.

but the difference is that a bus can easily be replaced with a subway extension while an LRT is almost impossible to get rid of (politically) when it gets severely overcrowded.

Huh? Where is the evidence of that please? Besides, if one is going to equate LRTs to streetcars, Toronto is replete with examples of lines being replaced by subways when they get overcrowded.

Look at the whole Scarborough RT fiasco right now. We are talking about replacing the deteriorating SRT with a costly subway, which is politically difficult.

Wasting a billion to build the Sheppard LRT then replacing it with a subway 20 years later when it becomes overcrowded (which would require closing the LRT during construction because of the plan to put the Don Mills end of the LRT underground) is a lot more expensive than simply building the Sheppard subway extension to begin with. The difference with replacing the old streetcar system with the Yonge and Bloor subways is that the old streetcar lines were built in the 19th century when Toronto was not a very big city and then was replaced with a subway almost 100 years later.

Ok, I think the issue that capacity. Don Mills is not congested enough like Yonge but I feel the subway should be one technology should be throughout the whole corridor. Not to peel people off the DVP. Because most people will still drive. We need a hell of alot more North South transit if we want to reach NYC Numbers.

Except that a) there is no evidence your line will be overcrowded in 20 years for one, b) the whole SRT fiasco has to do with the use of non-standard technologies with no economies of scale with the rest of the system, and not the lack of capacity per se.

The issue isn't the age of the old streetcar lines - it is, and should always be whether ridership justifies replacing it.

Well do you think the ridership north of Eglinton justifies a subway on Don Mills to Finch? Because I can tell you many people would switch to a Don Mills Finch station rather then RHC(in the future) so the ridership that is there now could increase.

I think that the DRL tunnel along Eglinton from ET Seton Park to Don Mills will be very steep to make it up the ravine from below the riverbed of the Don into the station at Don Mills. Either that, or we have to completely reconfigure the planned Crosstown station box to be, itself, very deep to accommodate the DRL. Of course, this means that the Ferrand stop will have to be axed (not altogether a bad thing) and the Crosstown portal would emerge somewhere near Wynford.

I imagine the DRL route slightly differently, at least in terms of its vertical alignment, than you're describing. I would have it run entirely at surface or above ground through Thorncliffe Park and crossing a bridge to over the Don Valley and ET Seton. The bridge itself would run at a rough diagonal from Wicksteed to a portal on the north west corner of the OSC parking lot, entering in a stacked fashion, and transitioning into the station right below the surface of Don Mills.

I don't think it would make sense to tunnel under the Don Valley here. I think that's a huge advantage of cutting through Thorncliffe, the relative ease of constructing the entire section from Eglinton to East York above ground.

I'm also not sure why people think this would spell the end of any northward DRL. To begin with, northern corridors aren't limited to Don Mills. The DVP, the rail corridor to Agincourt, the Richmond Hill Corridor and Vic Park seem like equally credible routes, depending on what the goals and constraints of the line end up being. More over, it could just as easily jink back onto Don Mills anyways.

I hope you realize that for Sheppard LRT to be overcrowded in 20 years, ridership growth on that line would have to enormoisly outpace that of everywhere else on the system (including downtown). I can guarantee you that won't be happening.
