AWS development & installation, United Kingdom
Automatic Warning Systems were introduced in the UK in 1950s. Trains are prevented from passing through a red “stop” light by a system known as AWS. A passing train detects the first magnet and the system is armed for automatic application of the brakes. Depending on the state of the second magnet, the brake signal is either cancelled or applied. Pandrol worked closely with Network Rail to develop a solution which overcame the issues they were having with ferrite magnets having poor resistance to being demagnetised by external fields.
