Perhaps, but that's certainly not how the original post read to me. And in fairness, that's also a function of the curve/track geometry - not just the equipment used. The benefit is quite high, I agree. But does it outweigh the cost, which will also be quite high? Dan

What makes you think that EMUs can handle tighter turns than regular rolling stock? Dan

Yeah. Primarily teething. They've run in J-trains in service, so I'm not sure why you continue to believe the bullshit that continues to be spouted online. And more expensive to buy, maintain and operate. Are you willing to pay more for your ticket and your taxes to cover the difference? It...

When did that change? Dan

It's hard to put much weight into that. Deer regularly hang out all the way down to the Bloor Viaduct. They even make it to the Leslie Street Spit not infrequently. The small patch of forest that has been destroyed, as painful as it is, is not going to adversely affect them in any way. Dan

A tamper is a big piece of the puzzle when it comes to laying and setting up track, but it is by no means the only one. Ballast needs to be dumped first in order to provide something to support the track itself. The ballast needs to be shaped in order to provide that support - so a ballast...

I think that you're conflating Metrolinx's agreement with the Canal Authority regarding their two "closed" slots (which represent the times for the weekday morning inbound and afternoon outbound rush hour trains) with there being an actual limitation on trains over the canal. Metrolinx is...

Or e) after all of the previous delays everything is going through its final checks now, and the line will be opening soon. If there had been some structural issue with the slab under Eglinton Station we would have heard about it by now. The TTC is really, really sensitive to issues like that...

That equipment was replaced several years ago with a high-rail school/activity bus. In any case, it wasn't considered a train but a "track unit", and so was not required to shunt any signals. Dan

That's because they haven't actually done any construction through here. It's been 2 tracks since the 1850s. Dan

Yes. Dan

Considering the weight and forces involved, a fence would not do anything. A wall would have to be quite robust - and thus, quite heavy - in order to do anything, and so would come with its own set of drawbacks. That's why most protections on bridges are limited to things like guard rails and...

You don't need millimeter precision for LRT track. You don't even need it for high-quality mainline track like the Kingston Sub. Dan

That's just it, for a greenfield installation it's easy because you can build in the protections from the outset. For something like a bridge - which is already quite solid - the mitigation measures may be as simple as building wing walls adjacent to the abutments. Dan

If the issues are similar to Crosstown, it's not that the contractor does or doesn't know how to lay to spec. It's that the spec is unreasonable, and Metrolinx is holding it to an unreasonable tolerance. You don't need millimeter precision for sidewalks and bike lanes, but that's the tolerance...

LRCs ran in smaller consists than the Siemens sets do. They're fixed length, after all. Why would you think that the same would happen considering that? Dan

Please be aware that there are a huge number of factual errors in that article. The issue is not necessarily that they don't work with 24 but they do with 32, but rather that the probabilities of failure are higher with 24 versus 32. And in large part that has to do with the physics of having...

All of GO's equipment use tread brakes. This regularly cleans the wheel surfaces, and ensures good contact is made. Thus, the only restriction that comes about is CN"s own 12-axle restriction. The Siemens cars and locomotives don't use tread brakes, only disc brakes. Thus there is no active...

Before I answer that......think about how that would look, exactly. And then look or think about any new grade separation and consider how much - or little - space there is between the tracks and the structure. So no, track does not need to be 30m from any structure. What needs to happen is...

That's correct. Maple, Rutherford and Downsview Park all are configured to have a third track between both platform tracks. It does appear that the second track will be completed between Teston and Concord, as they have built most of the track between Rutherford and Maple - they will just need...
