ADDED TALKING DEFECT DETECTOR AUDIO LINKS
Well, it has been a long time! I was in college in Buffalo way back in '96 when I first stumbled onto the WNYRHS website, and Wiki wasn't around back then. I'm glad these sound clips were still on their website, so this article could benefit!216.170.144.5 13:39, 2 October 2006 (UTC)

How are speed and train length measured?
I can see how many of these work (hotbox, clearance envelope, hanging equipment, axle count), but I can't figure out how you measure both speed and length just by watching the train go by. If you know one, you can calculate the other from the transit time, but I don't see how you can get both of those simultaneously. It would be good if somebody could update the article with something about this. -- RoySmith (talk) 14:12, 1 November 2021 (UTC)
 * There are two axle sensors so the system can compute the speed of the train every time an axle passes. At that point you just keep track of x = vt for each between space between axles and add it up.Sturmovik (talk) 11:58, 2 November 2021 (UTC)

 * I would hold off until it is determined if or how a hotbox detector was involved and even then it would not need a new section, just a referenced blurb discussing the limitations of the current technology.Sturmovik (talk) 19:47, 16 February 2023 (UTC)

There are indications that it was detected. One source says by three detectors prior to the derail. Unfortunately I'm unable to find a reliable source, so just leave it here for now. Gjxj (talk) 05:06, 23 February 2023 (UTC)

This article just shows North American ones
The scope of the atricle just narrows down on the situation in North America. However, there are similar devices across the World. e.g Heißläuferortungsanlage or just the situation in the UK could be implemented into the Article - Adtonko (talk) 13:08, 4 March 2023 (UTC)
