Safety paranoia doesn't actually describe what is happening...it's actually about liability. The reason the trains are so heavily restricted is because the engineers are believe they could be liable if things go wrong. Unlike with cars, where drivers are the ones who will be liable.

NHK World News recently released this short documentary on an LRT system that just recently opened 3 months ago in Utsunomiya in Japan. It gives you a cool look at how similar they approached an LRT system, but also how drastically different they did things in terms of things like design or the impact on urban planning/development.
They had 4 crashes within the first month if I recall...haha. Worth a watch if you have 30 minutes to waste and can tolerate the narrator that sounds like she's selling soap on a 1998 early morning infomercial: https://www.youtube.com/watch?v=KFQlDG9SFqE

The LRV was also presumably traveling at slow enough speed having just cleared the Erb/Caroline corner and also preparing to stop at the station. Based on the trailer, this truck was likely making a delivery to the Loblaws Independent Grocer.

I’d love to hear a lawyer’s expert take on this. I know that many ridiculous liability decisions have been taken by the courts, making liable the innocent victims (property and business owners, manufacturers) of the irresponsible behaviour of others, but even so I have trouble believing that the Region would really be liable if their LRVs went at 70km/h down King St. when motor vehicles are mostly doing 60km/h and there was a collision caused by a motor vehicle violating the traffic law.

You think lawyers will be immune to (or an immunity from) liability paranoia... I'm pretty sure they're the ones driving it... Or at least they are contributing. Lawyers are the absolute king of "don't say anything you aren't certain of". As for the specific situation, it's less about specific risk and instead about the absolute terror of anything unknown. The primary way engineers eliminate risk is by not doing engineering. They copy designs verbatim from books, so later they blame the book. But unlike roads, LRTs are rare, so there aren't the same kind of design guides available, so they don't have anything to copy from to limit their professional liability.

It's 150 meters from the last intersection so I wouldn't say it "just cleared" Erb and Caroline. While it's unlikely the operator is actually doing the speed limit there, 40km/h is very possible. At that speed the LRV stopping distance will be significant (a dozen meters maybe). Given the orientation of the truck, it was probably proceeding straight (the trailer is aligned in the lane), and made a turn, if they weren't signalling, the driver would have almost no warning about the impending collision.

Based on the trailer, this truck was likely making a delivery to the Loblaws Independent Grocer. I thought the speed limit through here was the new 30km/h, but apparently that's just from John St to Allen St. I guess the Region owns the rest due to the LRT tracks. It really should be 30 the whole way, especially the section next to the LRT station, since it has 2 pedestrian crossings.

Yeah let's just make it even slower than it is lmao.

I was referring to the road speed, since that might not have been clear.
Though if Waterloo convinced the Region to lower the speed limit on their portion of the road, I wouldn't put it past the Region to lower to speed limit of the LRT too...

To be fair, the LRT can’t go very fast on that block because of tight curves at each end. Unlike all the places where it can’t go very fast because the people in charge won’t let it go faster.

As the tram would not have been in the right side blindspot, the truck driver was likely fixated on the driver's side mirror to judge that the ass-end of the trailer was headed where they wanted it to go.

At that speed the LRV stopping distance will be significant (a dozen meters maybe). I understand what you are suggesting, but I still don't think the truck was doing that, I think he was making a turn. I doubt the train was able to drag the truck any distance, so I'm assuming it's position was the position it was in when the driver turned into the train. Given I saw it first hand, I have a good handle on the position, and the truck was exactly lined up for a turn onto Father David Bauer Dr., and while it is probably possible to reverse into the loading bay from there, if they were to go straight in from that position, they would back over the island. But I don't think it matters anyway, there is no excuse for hitting a tram. As for 40km/h, I think the thing that makes it less likely is the overly conservative operational safety policy which means they often operate the tram at more than 10km/h below the limit.

I happened to be going through today so I recorded the speeds on Google Maps. Ignore the navigation, I used car trip to get the speed to show up but I think it shouldn't affect the accuracy. https://i.imgur.com/2vryNOa.mp4 I didn't record after the station but it also got up to about 40km/h, slowing down to 10-15km/h for the bends. So a 30km/h limit would technically slow the trip down a very small amount. (12-20-2023, 10:46 AM)danbrotherston Wrote:(12-19-2023, 11:37 PM)Bytor Wrote: 40km/h is unlikely. See above to remove some speculation from your discussion. At least the operator I had today went by FDB at roughly 40km/h. |
