ČSN EN 15273-2

EN 15273 comprises three parts, namely: - EN 15273-1 that covers general definitions and the rules applicable to rolling stock and structure gauges; - EN 15273-2 that gives the rules for calculating the rolling stock gauges and the associated rules for the various profiles; - EN 15273-3 that gives the definition for the structure gauges. It explains the parameters concerned and gives a possible methodology for determining the structure gauges and the distances between centres of the tracks. The gauges included in these standards have been developed as part of their application on European railways. Other networks such as regional, local, urban and suburban networks may apply the gauge regulations defined in this standard. They may be required to make use of specific methodologies, particularly where: - specific rolling stock is used (for example: underground trains, trams, etc. operating on two rails); - the range of curve radii is different; - others, etc. The catalogue included in this European Standard only includes a selection of gauges and is not exhaustive. Each network is free to define the gauges in accordance with their own needs.
