The cameras are for capturing images of objects inside and outside of the vehicle. This system briefly works as follows; as the train approaches the signal it passes over a ramp between the rails, in which are placed two electromagnets (or a permanent magnet (see below), and an electromagnet). Because the permanent magnet is located in the centre of the track, it operates in both directions. In many countries around the world the rail network is one of the main transport routes.

The Web's largest and most authoritative acronyms and abbreviations resource. The driver then has approximately 2 seconds to cancel the warning by pressing and releasing the AWS/TPWS acknowledgement button (if a driver should collapse onto the button or keep it held down, the AWS will not be cancelled). 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). Below this speed, the caution horn warning will always be given, but it will be automatically cancelled when the electromagnet resets the system if the driver has not already done so. A cheaper alternative is the installation of a lineside sign that notifies the driver to cancel and ignore the warning. "The Automatic Warning System of Train Control (AWS), as it is called, which is described in this booklet is not, of course, the first apparatus to be devised for the purpose. In 1907 Frank Wyatt Prentice patented a radio signalling system using a continuous cable laid between the rails energized by a spark generator to relay "Hertzian Waves" to the locomotive.

This document defines the functional, performance and application requirements for the Automatic Warning System. Once so reset, a bell is sounded (a chime on newer stock) and the indicator is set to all black if it is not already so. Hudd patented his invention and offered it for development to the Automatic Telephone Manufacturing Company of Liverpool (a subsidiary of the Strowger Automatic Telephone Exchange Company of Chicago). [8] The LSWR installed the system on its Hampton Court Branch in 1911, but shortly after removed it when the line was electrified.[9]. The first system to be put into wide use was developed in 1905 by the Great Western Railway and protected by UK patents 12661 and 25955. Continually cancelling warnings can lead to a state of conditioning, sometimes called the "double yellow zombie" effect, where the driver fails to take appropriate action when necessary. [citation needed], The first useful device was invented by Vincent Raven of the North Eastern Railway in 1895, patent number 23384. Beyond the magnet, a lineside warning board will advise the driver of the speed requirement ahead.
