Excellent catch! Love it when there's alot of power at the head end.

That was the CN Hot Box Detector that broadcast the information on the CN road channel so that the train crew can hear it. It also reports to the Rail Traffic Controller (RTC) in Montreal. Some detectors also report the number of axles.
