Abstract
A sensing system for use on a tracked vehicle transporation system forms a sensitive floor beneath the lip of a platform. The floor is made up of a plurality of metal plates mounted on spring supports so that they can be slightly depressed if an abnormal load is applied to them. Such depression changes the state of a switch or like means through the intermediary of a cable and a lever.
