It was fast, but keep in mind there’s probably +\- 2 or 3 minutes to my posts relative to the event occurring, ijmorlan. It would not be a direct correlation that could be used for accurate timing. They are moving between UWaterloo and Willis Way only.
I saw them go through at Seagram; the absolutely massive crossing arm went completely nuts when it went up. It looks to me like it made the “up” switch, so the motor turned off. But, because the arm is so long, it bounced, and forced the pivot back off the switch. So, the motor pulsed “up” again, amplifying the whip... and it got worse and worse until I heard gears stripping. Then it faulted out, with the lights stuck on.
How stuff like this wasn’t found months ago is beyond me... if I was installing that stuff it’d be the first thing I’d check once I got power on it.
