Railway signalling symbols - Specification for symbols for circuit diagrams Ingestion-build-209418 Who is BS EN 40451 Scope This British Standard specifies the symbols to be used on railway signalling circuit diagrams but does not provide guidance on their application. It also gives a standard system of nomenclature and labelling of wires such that each wire can be readily identified with that shown on the circuit diagram. This British Standard does not cover symbols for high voltage power distribution, telecommunications or electronic products. These are covered
