This European Standard is applicable to the lines with standard track gauge (1435°mm) and wider track gauges of the heavy rail system and the vehicles that are operated on these lines, except portable trolleys as defined by EN 13977 and maintenance vehicles (e.g. rail mounted plant, cranes) in their working or travelling modes (see EN 14033-2). This European Standard describes methods of classification of existing and new lines of the heavy rail system and the categorisation of rail vehicles. This European Standard gives guidance to a reliable and established management of the interface between rail vehicles and the heavy rail network and does not impose any requirements on either vehicles or infrastructure. The application of this European standard enables to ensure the static route compatibility between a rail vehicle and the heavy rail network with respect to the vertical load carrying capacity. It contains requirements relevant to: - classification of the vertical load carrying capacity of lines of the heavy rail network; - allocation of rail vehicles to line categories (categorisation); - determination of payload limits of freight wagons. Out of the scope of this European standard are - assessments of compatibility based on the parameter axle load alone; - compatibility checks for cases where an additional dynamic analysis is required (for example according to EN 1991-2:2003, 6.4.4); - requirements relating to the maximum total mass or maximum length of a train; - the system used in Great Britain, where all lines and vehicles are classified in accordance with the RA (Route Availability) System. A guide to the equivalent categories in accordance with this European Standard is given in Annex M; - the publication of line categories. The requirements of this European Standard do not replace any regulations related to running behaviour of vehicles described by the assessment quantities for running safety, track loading and ride characteristics (see EN 14363).

This document gives guidelines for the cross wind assessment of railways. This document is applicable to all passenger vehicles, locomotives and power cars (with a maximum train speed above 140 km/h up to 360 km/h) and freight wagons (with a maximum train speed above 80 km/h up to 160 km/h) and track gauges from 1 435 mm to 1 668 mm inclusive. For passenger vehicles, locomotives and power cars with a maximum train speed between 250 km/h and 360 km/h, a requirement to demonstrate the cross wind stability is imposed. This document is not applicable to light rail and urban rail vehicles.

This document applies to passenger body side entrance systems of all newly designed railway vehicles such as tram, metro, suburban, mainline and high-speed trains that carry passengers. The requirements of this document also apply to existing vehicles undergoing refurbishment of the door equipment, as far as it is reasonably practicable. This document also specifies the requirements for testing of entrance systems. This document makes reference to manual and power operated entrance systems. For manual doors, clauses referring to power operation are not applicable. This document does not apply to the following: - entrance systems for equipment access, inspection or maintenance purposes and for crew only use; - doors on freight wagons; and - doors or hatches specifically provided for escape under emergency conditions.

This part of the ISO 22480 series defines technical criteria and control procedures which need to be satisfied by the constituent materials and the finished concrete sleepers and bearers, i.e.: precast concrete sleepers, twin-block reinforced sleepers, bearers for switches and crossings, and special elements for railway tracks.

The main requirement of concrete sleepers and bearers is the transmission of vertical, lateral and longitudinal loads from the rails to the ballast or other support. In use, they are also exposed to frost damage and to moisture, which can result in detrimental chemical reactions within the sleeper.

In this standard mechanical tests are defined which provide assurance of the capability of sleepers or bearers to resist repetitive loading and provide sufficient durability. In addition, controls are placed on manufacturing processes and tests to ensure that the concrete will not suffer degradation in service through chemical reaction and frost damage.
