    How can any system orientated maintenance shop allow anything like this to happen?


    “Plus, each train has been fixed and modified so many times over the years, not one is identical. They needed “a unique wiring diagram for every single train.”




    This should also raise major concerns about the procurement system and basic build of the units. Over their long lives the designers should assume that nearly every part will require repair or replacement so the idea that every fix had to solve a problem in any kind of unique way, may mean that they were all workarounds to deal with cars that were never designed for ongoing maintenance beyond routine scheduled maintenance.

    How many of us have cars more than 20 years old? Perhaps the city could retrofit the High Level and Fort Edmonton streetcars with CBTC technology.

    After reading that Journal story I almost have some sympathy for Mr Thales. So all of the old cars have non standard wiring? And the city added all that extra work?
    They still, today, have an unregulated power supply, which means the on-board computer can’t get the consistent 115 volts you’d get from plugging into a normal power outlet today.

    “The voltage can vary quite widely,” he said. It was so bad, when they first hooked five 40-year-old trains together, the voltage swung so low that the brakes came on.“

    Time to hit the gong!

    So you can't get a $500 APC UPS to regulate the voltage?

    Hahahaha!!!

    Maybe a $15,000 APC (same unit though). The bidding process isn’t cheap.

    Then there’s the electrical engineering studies that would have to be done first.


    Then in keeping with tradition, each car would be done as needed over years to ensure each one is uniquely equipped.

    You have to wonder how safe it is to have VOBCs installed without providing a constant voltage for them. It's a wonder they haven't had one of the suckers get fried yet.

    From the Journal article above:
    Edmonton’s Metro LRT line posed two major technical challenges to signals engineers — it has 13 at-grade crossings within three kilometres and required retrofitting 40-year-old trains with new technology. These challenges were underestimated.

    Going in, Thales had never applied its radio-signal based system to at-grade crossings. According to documents previously obtained by Postmedia, Edmonton officials identified that in their evaluation comments before awarding the bid.
    So City officials were aware of these challenges but awarded the contract anyway. We may be building an inferior street level system but at least it will have state of the art signalling must have been the mindset.

    Thales are the supposed experts in signalling and they said they could do it. It's not like they're "Bob's Rail Signalling Service" fro New Sarepta.

    That reminds me of the time I got drunk with some guys from Boston in a hotel bar in Seattle while the dig was going on. I recall that they said between the mob and the unions - Teamsters? Apparently this doubled the original price tag. Don't think the Ukrainian mafia had anything to do the Metro did they? lol

    I would expect so with a $25B final price tag, all in. That’s billions. The original estimate in planning was 2.8B. I know it’s not comparable but it just gave me thoughts of it.

    I suspect this whole debacle is a 50/50 combination of incompetence from the city and Thales, which is why it seems to drag on forever and seems so difficult to resolve. They keep on trying to blame and threaten each other. It reminds me of two guys in a leaky boat in the middle of the lake fighting instead of trying to fix it, except in this case the bigger problem is neither really has a clue how to fix things. Its worse because with the current city council, it seems the bureaucrats are never wrong and seldom held accountable.

    Why can't they replace the hard wired signalling system with something more modern like wireless? Wireless has only been around for 100 years.

    The method of communication isn't the problem. It's not that they're having shorts and faults on the wiring. They're having problems with the controls logic and sequencing; the software side basically. Whether it's wired or wireless is irrelevant.

    I believe I read that the gauge of wiring used was incorrect which can create com issues. I would explain where there’s so much uprooting of wiring alongside the Kingsway parkade.

    Software issues can stem from improperly engineered wiring infrastructure as well.
