This document specifies the requirements for the design, manufacture and testing of brake pipe accelerator valves.

La présent document définit les profils de roulement des roues de diamètre supérieur ou égal à 330 mm utilisées pour des matériels circulant sur voie normale européenne et et utilisé sur du matériel soumis à la Directive 2008/57/CE. Ces profils s’appliquent aux roues neuves livrées sous forme de roues seules ou calées sur essieux montés, ainsi qu’aux roues devant subir un reprofilage en cours de maintenance.

This European Standard specifies the functionality, position, constraints and control of a magnetic track brake system (MTB system) installed in bogies for use in emergency braking and in low adhesion conditions on Mainline Trains up to speeds of 280 km/h. It covers high suspension types of MTB only and not high/low and low suspension type of MTB. This document also contains test methods and acceptance criteria for an MTB system. It identifies interfaces with electrical equipment, bogie, track and other brake systems. On the basis of the existing international and national standards, additional requirements are defined for: - conditions of application for the MTB system; - retardation and brake forces; - functional and design features; - strength requirements; - type, series and vehicle implementation tests. For design and calculation a "reference surface" is established.

This European Standard specifies test methods and acceptance criteria for a brake system for use in self propelling thermal and electric trains, in the following document called EMU/DMU, operating on routes of the European conventional rail system network. This European Standard is applicable to: - all new vehicles designs of self-propelling thermal and electric trains; - all major overhauls of the EMU/DMU if they involve redesigning or extensive alteration to the brake system of the vehicle concerned. This European Standard does not cover: - locomotive hauled trains which are specified by EN 14198; - mass transit rolling stock which is specified by EN 13452 (all parts); - high speed trains being operated at speeds greater than 200 km/h which are specified by EN 15734-1 and tests in EN 15734-2. The functional testing requirements set out in this European Standard assume the vehicles are fitted with brake system architecture as defined in prEN 16185 1. The braking performance obtained by applying the tests defined in this European Standard can be used to assess compliance with the required braking performance as defined in prEN 16185-1.

This European Standard defines a set of reference masses for specifying the requirements for the design, testing, acceptance, marking, delivery and operation of rail vehicles. The reference masses defined in this document are as follows: - dead mass; - design mass in working order; - design mass under normal payload; - design mass under exceptional payload; - operational mass in working order; - operational mass under normal payload. These reference masses are defined with respect to the whole vehicle, but they can also apply to a specific system or component. The specification of values for tolerances applicable to reference masses is not in the scope of this standard. Tolerances can be required by an application standard. Additional loadings due to environmental factors, for example snow and retained or absorbed rainwater, are not in the scope of this European Standard.

This document establishes definitions and evaluation methods for wheel-rail contact geometry parameters influencing the vehicle running dynamic behaviour: - the rolling radius difference between the two wheels of a wheelset (Δr-function) which serves as a basis for all further calculations; - the equivalent conicity function from which are derived: - a single equivalent conicity value for a specified amplitude which is relevant for the assessment of vehicle running stability on straight track and in very large radius curves according to EN 14363; - the nonlinearity parameter which characterizes the shape of this function and is related to the vehicle behaviour particularly in the speed range close to the running stability limit; - the rolling radii coefficient which is used to describe the theoretical radial steering capability of a wheelset in a curved track. Additional information is given about the relationship between the contact angles of the two wheels of a wheelset (Δtanγ-function) and about the roll angle parameter. NOTE Out of the presented parameters only those related to the contact angle are relevant for independently rotating wheels of wheel pairs. Descriptions of possible calculation methods are included in this document. Test case calculations are provided to achieve comparable results and to check the proper implementation of the described algorithms. To validate alternative methods not described in this document acceptance criteria are given for the equivalent conicity function. This includes reference profiles, profile combinations, tolerances and reference results with tolerance limits. This document also includes minimum requirements for the measurement of wheel and rail profiles as well as of the parameters needed for the transformation into a common coordinate system of right- and left-hand profiles. This document does not define limits for the wheel-rail contact geometry parameters and gives no tolerances for the rail profile and the wheel profile to achieve acceptable results. For the application of this document some general recommendations are given.

The gauges and processes included in this standard have been developed for application on mainline railway networks using various track gauges. Other networks such as urban and suburban may apply the gauging rules defined in this standard but are outside of its scope. For a given defined gauge, the application of the rules contained in EN 15273-2, combined with corresponding parameters and reference profiles given in EN 15273-4, makes it possible to determine the maximum exterior dimensions of a vehicle (maximum vehicle construction gauge) compatible with infrastructure gauges obtained according to rules defined in EN 15273-3. For absolute and comparative gauging, the application of the rules contained within EN 15273-2, combined with infrastructure data defined in EN 15273-3 in accordance with EN 15273-1 makes it possible to determine the dimensions of a vehicle. EN 15273-2 is applicable to new vehicle designs, to modifications to existing vehicles and for checking existing vehicles to be used on another route or network. This European standard contains: — the rules for rolling stock for all defined gauges; — the swept envelope calculation process used for defined dynamic gauges, absolute and comparative methods; — the list of documents required to assess vehicle conformity to this standard.

This document is a catalogue of existing gauges and provides data for static, kinematic and dynamic gauges. This document is intended to be used with prEN 15273-1, prEN 15273-2 and prEN 15273-3. Other networks, such as urban and suburban, can apply the gauging rules defined in this standard but are outside of its scope. This document provides for each gauge the associated basic data (such as track gauge, limits for cant and cant deficiency, range of lateral and vertical curvatures), formulae for the lateral and vertical projections and other reference parameters. NOTE The rules given in this standard are not applicable to the gauges "S" and "T" referred to in 4.2.3.1.

This standard: — defines the various profiles needed to install, verify and maintain the various infrastructures near the infrastructure gauge; — lists the various phenomena to be taken into account to determine the infrastructure gauge; — defines a methodology that may be used to calculate the various profiles from these phenomena; — lists the rules to determine the distance between the track centres; — lists the rules to be complied with when building the platforms; — lists the rules to determine the pantograph gauge; — lists the Formulae needed to calculate the infrastructure gauge. and is applicable for various track gauges. This standard defines the gauge as an agreement between infrastructure and rolling stock, and 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) compliance of the operating rolling stock with the gauge concerned; 2) maintenance of this compliance over time. For a given defined gauge, the application of the rules contain in this part 3, associated with useful elements contained in EN 15273-4, makes it possible to determine the minimum dimensions of an infrastructure. Therefore, this infrastructure is compatible with vehicle gauge having the same designation, and obtained according to rules defined in EN 15273-2. Other networks such as urban and suburban may apply the gauging rules defined in this standard but are outside of its scope. For absolute and comparative gauging, the application of the rules contained within EN 15273-3, combined with vehicle data defined in EN 15273-2 in accordance with EN 15273-1 make it possible to determine the dimensions of infrastructure. NOTE The rules given in this standard are not applicable to the gauges “S” and “T” referred to in clause 4.2.3.1.
