Maybe let's stop buying crap from Bombardier...

You do know that Alstom bought Bombardier. They are now just one of several different models that Alstom now has available.

What crap? As discussed in two different posts above, there haven't been any big issues from Bombardier that impact operations. New equipment always has teething problems. Both the Flexity introductions seems relatively smooth.

seriously... if 3mm for a TRAM is causing these problems, they are also guilty for buying an inferior product. this is not a HSR, its a slow moving tram that should have plenty of tolerances. dont tell me 3mm is what caused a derailment...
i find Verster's comment regarding MM precision required very difficult to believe. thats what youll need for NASA rockets, not TTC rockets. hes probably just pulling random quotes out of his ass to hide the fact that ML and crosslinx both shit to bed on managing this project.

What does the quality of the rolling stock have to do with the track being out of spec? You are saying if they bought "better" rolling stock it would be able to handle the 3mm gap?

 

[Bordercollie]

I think the bigger question is do those sleepers have the capability to adjust the gap by 3mm? Or do they need to replace all of them? In that case would it be easier to buy wheels that are 3mm wider? Is that even possible?

From 2021. See link.

29 January 2021 – Alstom announces today the completion of the acquisition of Bombardier Transportation. Leveraging on its clear Alstom in Motion strategy and its strong operational fundamentals and financial trajectory, Alstom, integrating Bombardier Transportation, will strengthen its leadership in the growing sustainable mobility market by reaching a critical size in all geographies and integrating further solutions and assets to better serve its customers worldwide.

The enlarged Group has a combined proforma revenue of around €15.7 billion[1] and a €71.1 billion[2] combined backlog. It employs 75,000 people worldwide in 70 countries, has unparalleled R&D capabilities and a complete portfolio of products and solutions.

“Today is a unique moment for Alstom and the mobility sector worldwide, with the creation of a new global leader centered on smart and sustainable mobility. More than ever, the world has to engage in a deep environmental and social transition to be able to address the great challenges of urbanization, equal opportunity to economic development and climate change. Transportation, essential to the working and social life but with great environmental impact is at the heart of this transition. Our responsibility, together with the 75,000 people of Alstom today, is to transform our unique set of assets created by this transaction into the enabler of this necessary transformation. Our responsibility is to bring the innovation required for such extreme challenges and that all communities throughout the world, as they are traveling to meet loved ones or to work, can have access to the same quality of service and efficiency, while caring for our planet.” said Henri Poupart-Lafarge, Chairman and CEO of Alstom.

Except now we've found out that Finch wont open until 2024 now, and i'm sure Hurontario will be delayed in very short order.

well did you honestly think that Finch wouldve opened in 2023 given what we saw even last year? The pandemic added at least 1 year to ever infrastructure project.

well yes... if the rolling stock doesnt even have 3mm tolerance then they bought a Diva product that has a too extremely tight operating envelope. Do you honestly expect the track to maintain this NASA level of precise alignment throughout its service life? eventually they will have to be replaced. 3mm is NOTHING.. thats the difference that you get from thermal expansion. 3in or even 3cm is something substantial.

actually on that note...just watch the track actually shift after this rework 3mm due to thermal expansion.... that would be the most hilarious and baffling thing to see.

Ok, fair enough.

Flexity equipment doesn't have this issue elsewhere. Presumably there is a range of acceptable track gauges - but if you are outside of it, then it's a problem.

I'd assume thermal expansion and aging are all factored into the design tolerances.

You see them using track geometry gauges all the time while installing track elsewhere. Clearly they weren't being as careful on Eglinton. Or perhaps they had incorrectly calibrated their gauge.

Hmm, if they use a gauge to check the gauge, is it a Track gauge gauge?

It's not so much me believing it (because I didnt and one could tell there's no way it can be opened this year given the current construction state on Finch), it's more of Metrolinx peddling inaccurate project completion dates.

Measure 100 times, cut twice.

well clearly even 100 measurements apparently wasnt enough....

honestly i have a feeling that they are also trying to milk every last dollar out of this project now that all bridges have been burnt.

But 3mm out of scope before heat expansion. Which could bring it to 6mm which could lead to a derailment.

You have to factor in the margin of error based on correct specs.

This is the kind of thing that resulted in the delays of the TTC Flexity cars. If the panels don't fit how do you build the cars?

Maybe there is a 1mm tolerance but if they are 2mm out of spec it's not going to fit. So do you then build cars that have 3mm tolerance? Do you want them to rattle themselves to pieces?

The stupid part about all of this is this line is based on standard gauge, nothing special. Did they calibrate the machines wrong? One cross over or one section I can understand, but the whole line? Clearly the inspectors from Metrolinx must have been drunk or something.

The big question here is how widespread is it

If it's only for a short section then it's not the end of the world but if it's widespread through the entire line where there's grass then it's an absolute disaster. At that stage I don't think any free repairs would fix the harm in time and reputation.
