I wouldn't count on them doing what you propose, based on how careful and delicate every other aspect of the pull-through testing has been. Everything has like 20 people signing off on things and checkboxes and clipboards and so on, it's not like they're just slamming it through saying "Oh yeah, good enough".
Good point. It’s hard to say exactly what impact it will have. Although I would expect that the other track can still be tested unless, again, I misunderstand the geometry. Actually this raises a question in my mind — how do they record that they have completed a pullthrough? Start and end points? Tick off each pole as they pass it? This might relate to how they deal with an impassable stretch of track. Depending on how they do it my suggestion might be fine or it might be easier just to hold off at some convenient stopping point until the work is done.

They've now revised the design for the shroud around it:

Cool to see that’s been fixed. Weird that the initial design wasn’t right: I mean, presumably this isn’t the first size detector in the country? It’s not like a specific curve, or the placement of a sign, either of which obviously are custom-designed for our system. I would have thought that the entire oversize detector would be a standard design, with at least dozens of existing installations.
I have to say, I’m not sure why you would delete any of your posts. I think you come out looking pretty good — you noticed a problem, noticed it’s been fixed, then nicely corrected somebody who assumed it would fail dangerous. We want to have the good information out there alongside the nonsense.
