This section covers equipment detectors.  Their job is to "find" bad equipment on the trains as they go by.  Modern detectors employ a variety of technologies, and range from the latest in IR (infra-red) sensors, to simple weight activated electro-mechanical switches for detecting dragging equipment.  As always, these pages are a work in progress, if you have something you would like to contribute, please send to toddgp30@yahoo.com.  If you submit something, please do a walkaround and try to get as much info as possible.
