Ha, true enough. It was funny listening to the detectors when 3985 was running across Missouri and Illinois last fall. Up to that point, I may have heard a hot box detector go off maybe twice in 10+ years of railfanning, but with 3985 it set it off for multiple axles! IIRC, most detectors don't work below about 10 mph.

From the TAFL (DO49 in my area) the CN ones have an ERP of only 5.5 Watts. and an antenna height of only 3 (metres) or 10 feet. They use a no gain ground plane antenna which looks like a Sinclair SRL 217 to me.

Combination of a wayside box, wheel and brake disc wayside detection plant In most locations, where a hot box detection system is positioned, there is also a hot wheel detection system and a hot disk detection system. The main reason for this accumulation of sensors are the installation costs for a single system .

HOT AXLE BOX DETECTORS (HABD) – 3. We are only interested in measuring the temperature of the axle box and not that of the whole underside of the train. To do this we use an optical system to focus the infrared energy emitted by a small area of the axle box. The detector will accept all infrared frequency equally so two filters are ...
