scope:

This standard: - defines the various profiles needed to install,verify and maintain the various structures near the structuregauge; - lists the various phenomena to be taken into account todetermine the structure gauge; - defines a methodology that may beused to calculate the various profiles from these phenomena; -lists the rules to determine the distance between the trackcentres; - lists the rules to be complied with when building theplatforms; - lists the rules to determine the pantograph gauge; -lists the formulae needed to calculate the structure gauges in thecatalogue. The defined gauge includes the space to be gauged andmaintained to allow the running of rolling stock, and the rules forcalculation and verification intended for sizing the rolling stockto run on one or several infrastructures without interference risk.This standard defines methodologies to demonstrate gaugecompatibility between infrastructure and rolling stock. Thisstandard defines the responsibilities of the following parties: a)for the infrastructure: 1) gauge clearance; 2) maintenance; 3)infrastructure monitoring. b) for the rolling stock: 1) complianceof the operating rolling stock with the gauge concerned; 2)maintenance of this compliance over time. The gauges included inthese standards have been developed as part of their application onEuropean railways. Other networks such as regional, local, urbanand suburban networks may apply the gauge regulations defined inthis standard. They may be required to make use of specificmethodologies, particularly where: - specific rolling stock is used(for example: underground trains, trams, etc. operating on tworails); - use occurs in other ranges of radii; - others, etc. Thecatalogue included in this standard only includes a selection ofgauges and is not exhaustive. Each network is free to define thegauges in accordance with their own needs.
