Railway Signalling and Safety

Harry Ryland


Railway signalling has evolved over the last 150 years to provide an extremely high level of safety, both for the railway staff and their customers. In the last 20 years, traditional approaches to safety have been modified by the introduction of microprocessors into a number of areas of signalling. New standards call for ever-improved methods for developing safety systems and software. In addition, safety cases have to be presented for all new equipment and installations. These trends, together with the increasing commercial pressures, result in a demand on those in the signalling supply industries to produce ever more innovative systems, software and methodologies.
