AWS was based on a 1930 system developed by Alfred Ernest Hudd[3] and marketed as the "Strowger-Hudd" system. Each distant signal had its own battery, operating at 12.5 V or more; the resistance if the power came directly from the controlling signal box was thought too great (the locomotive equipment required 500 mA). Because the permanent magnet is located in the centre of the track, it operates in both directions. The Automatic Warning System (AWS) was introduced in the 1950s in the United Kingdom to provide a train driver with an audible warning and visual reminder that they were approaching a distant signal at caution. It is basically an auditory warning system, with a visual display reminder. The motion sensor unit includes at least an acceleration sensor and a gyro sensor, configured for sensing motion of the vehicle. To ensure that the mechanism had time to act when the locomotive was travelling at high speed, and the external current therefore supplied only for an instant, a "slow releasing relay" both extended the period of operation and supplemented the power from the external supply with current from the locomotive battery. , since the electromagnet is de-energised, the 'sunflower ' indicator in the cab and no action has be.
