ION - Waterloo Region's Light Rail Transit

As a reminder, these arrays will trigger a derail device further down if a freight train is too high or too wide to safely pass along the shared LRT corridor.

So is there a red light or something before the de-railer?  I only ask say, if someone put a bucket on a boxcar, and set off the detector, derailing a train seems extreme...

I don’t know about the north end, but the south end one has a signal right at the derailer. I’m not aware of any other signals but I haven’t gone down the line further to check. Normally that wouldn’t give time to stop but at the speeds they go in this section they would be able to stop before reaching the signal.

If the detector works like a hotbox detector, it will also advertise its result after the train goes by over the radio. Those detectors advertise their location, how many axles were counted, and whether or not there were faults. But I don’t know if that is how overgauge detectors operate.
