Emco Wheaton engineers responded to a challenging request from the Turkish Rail Authority with an innovative anti-theft solution. The Todo-Matic adaptor, which is mounted on the rail car, incorporates a switch that senses the magnet mounted on both the coupler and the adaptor cap. This connection generates an 'on/ off' signal that alerts the locomotive driver if a coupler or cap is disconnected from an adaptor without authority or at the wrong time. The coupler, cap and adaptor are designed so that when correctly joined the magnet and switch will align. Rob Williams, Emco Wheaton's sales manager for Todo products, explains: "When the cap is removed by an unauthorised person, a magnetic switch fitted on the tank unit immediately sends a signal to a control unit in the driver's cab. By notifying the driver of the unauthorised removal of the cap, it leads to a reduced chance of stolen fuel."
