Metrolinx: Sheppard East LRT (In Design)

Haven't we discussed this enough times? Could be tight.

But really - is a low bridge that much more expensive per kilometre than a tunnel?
Wasn't thinking about costs - just what's feasible. Your point was that we can easily eliminate a station if we just go with a deep tunnel - my only comment is that tunneling this portion may not be possible.

My point is that we can skip the station at Bathurst - it doesn't really matter how the line is built. They had a plan back in the late 1980s when this was designed - I haven't seen the plans.
 
For Sheppard East, it may be sufficient to build a new bus-only bridge over 404, and then add a mixed-traffic express bus that reaches the east end of Sheppard. The capital expense will be under $100 million.

The new Meadowvale Rocket can run from Don Mills Stn to Port Union on weekdays. On summer weekends/holidays, it can run to the Zoo instead, and will be well used.

Money saved from Sheppard LRT, can be used to build two other LRTs in Scarborough, connecting STC to Centennial Progress campus, UTSC, and Malvern.

In 15-20 years, plans for the Sheppard corridor can be revisited. Hopefully, SmartTrack and the Relief line will be running, or in the final stages of construction by that time. Then, if the ridership forecast for Sheppard look better than now, the eastward and westward subway extensions can be back on the table.

No, its cheaper - probably half the cost.

I would put one track on each side of the roadway bridge. About a 300m long bridge - it should cost about $10M for each of 2 bridge structures (plus tracks, signals, etc.) - maybe add $5M is the bridge is to be covered (with glass?)
The tracks would emerge with portals close to the bridge so that a Bathurst Station (and Senlac Station) would be close to the surface and relatively cheap.

All this contortion just to avoid having to build a 7-stop subway, that will be entirely above grade southeast of Agincourt - hence cheaper to build than most other subway plans being tossed around here. Heck, the whole thing could be elevated for the most part if TBMs are that big of an issue.

No wonder some people think some people are motivated by spite.
 
The key is to avoid any type of cost reductions to make sure the East subway extension looks as expensive as possible. That way subway will not be considered.
 
When Eglinton opens, the public will get used to the idea that LRT can run in a tunnel. Sell them that over subway then.

That's not a bad idea. All that's needed is to widen the southern bridge by one lane, and build a bus only fly over on the north side of sheppard so busses can bypass the disaster area around the 404 bridge and then merge back onto sheppard. As long as the busses can work with the sloping, space would not be an issue.
 
How the Sheppard East LRT could be extended west to replace the Sheppard Subway.

Wow, if Sheppard is having that kind of LRT, there will be a lot less opposition - high platforms, clearly defined station structures; though sadly I think the whole point of the video is to show off the retractable catenary..

Since the current subway platforms in all the subways in Toronto are hollow, they'll lower the Sheppard platforms and use low-floor light rail vehicles.

That would be a nightmare. Lowering the elevator shafts wouldn't be easy. Nor would the escalators.

More likely, they'd fill up the tracks to the current platform height, and simply spec vehicles that would fit in the resulting tunnel.

There are a few systems that have done this kind of adjustment. They basically made the platform edge the new height and put in stairs and wheelchair ramps to the central platform section with the elevators/escalators.

Sheppard stations have a ton of invisible space behind knockout walls given quite a bit of room to make these kinds of adjustments.

Also worth noting, Sheppard escalators are already going through their mid-life rebuild. They'll be fully replaced in another 15 years. Putting in longer version wouldn't increase costs much at that time.
