Railway applications. Systems and procedures for change of track gauge - Automatic Variable Gauge SystemsWhat is BS EN 170691 Railway track gauge systems about? BS EN 17069 is a European standard on railway applications that discusses railway track gauge systems. BS EN 170691 is the first part of the BS EN 17069 series of documents that defines the interfaces and gives guidance for the design of systems and procedures for change of track gauge and also their assessment for technical approval, for the automatic variable gauge systems. BS EN 170691 focuses

the test method may also be used to demonstrate the mechanical robustness of specimens and/or to study their dynamic behaviour
