Eglinton East LRT | Metrolinx

[Northern Light]

Could it possible to build the new LRT station one level up from the SRT tracks? Or baring that, perhaps build the station immediately west of the SRT platform and have it slope up through the SRT station until it clears the GO trains?

I'm not an engineer or architect by trade, and don't have the schematic drawings of Kennedy Station; that said, my instinct is that its a 'no'.

Lets start with option A above...

The structural columns that currently support the SRT level may or may not have sufficient load bearing capacity to handle another level on top of that, that would allow for trams/trains.

If not, then you would either require a new set of columns, or you would have to widen/reinforce the existing ones. In the context of the existing station, that's complicated, do-able, but both costly and would eat in to existing space in the bus terminal and the concourse, and may encounter other conflicts.

You also then need the stairs and escalators to reach the upper level, those too require supports and take up room on lower levels, you also need them to arrive at your newly created level at a reasonable grade in a usable location. That's a lot to ask.

****

option B, immediately west of the current tracks. Right, but you need to get up to grade to clear the GO Tracks over a fairly short distance. That would mean, likely, re-sloping the grade of the existing tracks through the station. That is also a structural issue. You would be adding load, and you might have to cut off/open the roof on the east side since the rails would now be higher, and you've have to prevent people from accessing the now former platforms in some way as well.
That part isn't hard.......... but back to the grade issue. It depends how much more vertical clearance we need. I'm not sure w/o the drawings how much more is required, the photo suggests a good 2M for sure, but it might be 3M or more.

If you do that, at a 3 degree incline, it will take you between 40M (2M meter rise) and 80M (4M rise)

Here's a calculator for that if you wan to play around:

Elevation Grade Calculator

Elevation grade calculator determines the grade or slope of a specific earthen area, given its "rise" and "run".

Keep in mind you want the grade as low as possible, especially from to/from a stopped position. Depending on rolling stock selection, a grade of up to 5 degree incline may be workable, but a more conservative assumption would be prudent.

You don't want the platforms themselves to be inclined.

Completely on MX regarding the tunnel, that was another MX screwup, but I don't think there are the numbers for a separate extension. And again, I don't think the TTC likes mega long lines at all.

Ehh, there really was no other way to extend the subway, and remember, the plan was for the Scarborough LRT when the Eglinton LRT was starting construction. It was the city of Toronto that demanded a subway.

All true, but I mean the crosstown tunnel to Brimley, should have been clarified.

Truly the worst map i ever made, I don't know what i was thinking with those colours. Failed retro aesthetic i think?
Also this map just makes me think about how a network like this with BRT is so much more attainable with almost all of the same benefits, and then some. Inspiring me to update it with some better ideas.

Simpler may be better.

1. Draw in the Ellesmere BRT - maybe move it up to Centennial College and then along Progress to a new Ellesmere GO station. That eliminates the need for 1 branch.
2. Go through Malvern instead of along Sheppard. This eliminates another branch.
3. Add a Gondola from Morningside to the Zoo. This eliminates another branch.

I will admit your colours are better than mine.

Given the relative success of line 5 Eglinton so far, it makes me wonder if an EELRT is still feasible if there are less stops and it runs either elevated or underground.

 

[KhalilHeron]

to make the investment worth while i think theyd have to either cut a third of the stations or preferably build it as brt alongside a line 4 extension to STC and UTSC

Can't begin to talk about EELRT or anything of that nature without knowing were Sheppard east will stop.

That imo is the real issue.

Also, lets see how signal priorty impacts finch and crosstown, and then we can really begin making assumption about the feasibility of the surface rail..

Personally I still think we need full grade seperation regradless.

I think we can safely assume it's at Sheppard East station (at McCowan - though perhaps not the most useful name with 14 or more subway stations on Sheppard).

Honest question, why can we be so sure ?

I thought Sheppard was looking at 3 or 4 different options

Given the design of Sheppard East station and bus bays? Yes.

Ignoring the extension east of McCowan and west of Yonge, it's basically two options. But I think the Scarborough Centre option is simply there for them to eliminate it.

It makes no sense to move those travelling eastbound on Sheppard to Scarborough Centre and have them change 1 stop to get over the 401. Other than this "consultation" everything that comes out talks about Sheppard East.

OK I get that odds are that the exstension is likely not going to stc, etc..is highly

However, until we know for sure where Sheppard is going...what is the point of talking about EELRT.

Realistically we're 3/4 years aways from a Sheppard east annoucment which puts it squarely in the political calendar.


We also have majoral elections this year.. transit is sure to be a massive part of that conversation...

Imo, until I see whose winning that election and the next provincial elections, I'll remain skeptical of any transit plan without shovels in the ground.

Sheppard AND EELRT included.

I think you hit on the problem. It is not to decide Sheppard and then Eglinton East.
It's to consider them together and make both optimal - even if one willl be built later.
To me, it's either you have Eglinton East going to Malvern and then Agincourt or Malvern and then Centennial and STC.
Would a BRT on Ellesmere change this calculation?
But I think it's intended to end the Sheppard subway at McCowan and ???
and it's intended to terminate the on-street Eglinton LRT at Kennedy - and to be it's own grade-separated transit loop with multiple destinations.

They want to go to STC still. A chance the LRT will go to Agincourt.
