    So the bearing hub failed and the wheel let go. Similar to the failure that sometimes sends a wheel flying off a car or truck on the highway.

    At this point, the low-floor platforms and LRVs needs to be replaced with high-floor platforms and rolling stocks even if it means replacing LRT services with busses temporarily. Since there are many stations that uses side platforms configurations, upgrades can be phased in where one station would be the transition point with one platform upgraded to high floor and the other still original low floor. Low and high floor rolling stocks be operated simultaneously. Transition point would be at side platform stations with changeovers and/or crossovers nearby. Once a station is fully upgraded, when relocating transition point, bus services would fill in the gap until transition point relocation to another side platform station is complete or all upgrades are complete.

    This is crazy. So is this an engineering fault? And is it on all wheels on all cars?

      Biggest issue is on the powered bogies at the ends of the train. The 3 idling bogies in the middle modules seem to have less / no issue.

    You can hear the absolute _grinding_ that takes place whenever the train passes through any area that has a restraining rail. It was a lot quieter over the the next few weeks after the long shutdown, but I'm assuming things shifted around a bit with temperature. I'll be honest, I have no idea what codes or regulations requires the use of these rails in Canada/US, but from what I understand, these wheels where designed assuming said restraining rails didn't exist. So... why do we have them if they're causing more problems than they solve? Can't we just rip them out?

    • @Condorcounter
      @Condorcounter 11 месяцев назад +1

      The back of the flange is (almost) never supposed to contact the restraining wheel. What you are probably hearing/feeling is a combination of the bogies “hunting” on the curve, the wheel flanges touching the outside rail (TTC streetcars do this on all curves) and corrugation of the railhead. The latter needs to be ground smooth on a monthly to yearly basis on curves.

    • @ARitzCracker
      @ARitzCracker 11 месяцев назад

      @@Condorcounter Don't bogies hunting the curve make a higher-pitch screeching sound? This isn't the same sound. Again, what leads me to believe that the restraining rail is what's causing the excessive lateral forces is that the low-pitch grinding noise went away for a bit after the restraining rails where loosened, but the noise came back after the city had started having the big temperature fluctuations at the beginning of fall. I know I might be making correlations where they don't exist. But adjusting the restraining rails to ensure that the flange doesn't make contact was what took so long for full service to be restored. They adjusted all the restraining rails by a couple mm's to meet the "no contact" requirement, but, well, that's still within how much a track can warp as temperature changes.

    Yes, they have installed “bugs” to listen for vibrations of this type, but nothing “sensed” yet. Remember there have only been three such bearing failures so far and because they are now doing frequent preventive maintenance, they may not have any more failures. For a long time.
