No, I guess what I'm getting at is, yeah, I could have guessed it might be like that too - but we don't know the exact type of sensor they're using. I was wondering if someone did - I don't recall ever seeing a setup like this anywhere in the world that I've ridden trains. I design automation - I know sensors.
There's a high/wide detector on the CP Windsor Sub at MP 102.4 just off Manning Rd. in Tecumseh, ON that's similar to what will be installed on the Waterloo Spur. It looks to be an array of either infrared sensors or lasers. It transmits a radio message about whether the train fits in the clearance envelope for the rail tunnels between Windsor and Detroit.
It can be seen in this Street View:
