Maybe someone with more knowledge can chime in? @drum118 can we really blame it all on North American-spec tracks? Would European-spec wholly solve the premature wear?

If grooved rail would fix everything, why did Alstom agree to resume bearing redesign work (back in 2024... which is slated to be finished by 20XX?)

They walked away in 2025 as it wasn't the worth the cost to fix the design for 200 NA LRV;s compared to the 8000 in Europe and elsewhere that use groove rails. Mississauga first LRV was the test car sent to Kingston to deal with the issue.. They kill the NA market for themselves for LRV's over this issue.

Was there a press release for this? Alstom's not going to change the cartridge bearings for the bogies?

But aren't the Hamilton LRVs going to be Citadis Spirits too? Or has that changed? I guess it's too late to change for Hurontario (all or almost all of the vehicles are delivered already).
 
How does the grooved rail help? I thought that the rubbing of the guide rail causes too much stress on the bearing?

Why not replace the bearings at 80K instead of 100K?

The bearings are supposed to last 1,000,000 km, not 100,000 km

This is the timeline I see:

May 27, 2024; Alstom halts work on redesign hailed by city as 'final fix' to LRT woes: https://www.cbc.ca/news/canada/otta...ed-by-city-as-final-fix-to-lrt-woes-1.7213904
Sep 12, 2024; Alstom resuming work to redesign troublesome LRT bearing: https://www.cbc.ca/news/canada/otta...to-redesign-troublesome-lrt-bearing-1.7321264

I think @drum118 is saying Alstom halted the redesign a second time.

Do they need to use Citidas for their whole fleet? Could they order Flexity's for the expansion? I know a mixed fleet is not ideal but in this situation it might be better.

There are more needed in Toronto for the Eglinton W line and possibly a Scarborough LRT.
 
What do you mean by this? If you're talking about the 61/62/23 its often better than 20 min headways and frequently uses artics with the occasional double decker.

From Heron I waited 25min for the 61 to Kanata. It was an LFS packed to the brim. This was mid morning on a week day. Is that normal?
 
No bus to Kanata stops at Heron now that the 88 has been bifurcated, and the 60s have never gone that way. Hard to call any of OC's recent operations normal but it sounds like you got doubly unlucky, once with the delay and again with the 40ft. OC has no 60s or DDs on order so when they're gone, they're gone; I wouldn't be surprised if more LFS's end up on rapid routes.

Presumably Teron, which is in Kanata. Heron is in the southeast

Girder rail is not the issue. It is an antiquated technology and isn't used in Europe in large measures, or anywhere else for that measure. Everyone uses standard T rail now because it's what's readily available in a variety of different sizes and profiles, and if you play your cards right you can use each piece twice.

What is still used in lots of places is girder guard rail - and even here in Toronto. It's a totally different beast and with a difference purpose.
