ION - Waterloo Region's Light Rail Transit

Hi MacBerry,

I design precision high-speed automation. I understand fully that things don’t always work or go as planned. No one is saying that things shouldn’t be fixed.

My issue is that heavy construction wrapped up a year ago. Track measurements resulting in the discovery of fatal flaws requiring concrete to be jackhammered should have been taken a year ago, not months before service start. It is now a critical path item which will undoubtedly result in delays.

Had it been resolved last spring/summer, there would be no impact to service start. Now they are holding up testing.

It's not holding up testing too much. They can still do testing on the sections of track that aren't closed. As for why they are doing it now the reason is simple: they are finally testing vehicles. one of the downsides to doing embedded rail is that you have to remove parts of the concrete to realign the rails if they go out of alignment for any reason. one of those reasons is the concrete curing process.
