EN 13103-1:2017/prA1:2020
Tähtaeg 15.03.2020
Railway applications - Wheelsets and bogies - Part 1: Design method for axles with external journals
This European Standard: — defines the forces and moments to be taken into account with reference to masses, traction and braking conditions; — gives the stress calculation method for axles with outside axle journals; — specifies the maximum permissible stresses to be assumed in calculations for steel grade EA1N, EA1T and EA4T defined in EN 13261; — describes the method for determination of the maximum permissible stresses for other steel grades; — determines the diameters for the various sections of the axle and recommends the preferred shapes and transitions to ensure adequate service performance. This European Standard is applicable for: — axles defined in EN 13261 — powered and non-powered axles and — all track gauges3. The powered axle design method of this European Standard applies to: — solid and hollow powered axles for railway rolling stock; — solid and hollow non-powered axles of motor bogies; — solid and hollow non-powered axles of locomotives. The non-powered axle design method of this standard applies to solid and hollow axles of railway rolling stock used for the transportation of passengers and freight that are not considered in the list above. This European Standard is applicable to axles fitted to rolling stock intended to run under normal European conditions. Before using this European Standard, if there is any doubt as to whether the railway operating conditions are normal, it is necessary to determine whether an additional design factor has to be applied to the maximum permissible stresses. The calculation of wheelset axles for special applications (e.g. tamping/lining/levelling machines) may be made according to this European Standard only for the load cases of free-rolling and rolling in train formation. This European Standard does not apply to the loads induced by the vehicles in their working mode. They are calculated separately. This method can be used for light rail and tramway applications.

Railway applications - Braking - Requirements for the brake system of trains hauled by locomotives
This European Standard specifies basic requirements for the braking of trains hauled by locomotives: - For trains hauled by locomotives and intended for use in general operation each vehicle is fitted with the traditional brake system with a brake pipe compatible with the UIC brake system. NOTE This ensures technical compatibility of the brake function between vehicles of various origins in a train (see 5.4). - For trains hauled by locomotives and intended for use in fixed or predefined formation, the requirements on the vehicle and the train are necessary. In the case of a UIC brake system, this standard applies; if not, the EN 16185 series or the EN 15734 series applies. If concerned, the UIC brake architecture described in this standard (see 5.4) can be used for brakes for multiple unit train and high speed trains and urban rail described in the EN 13452 series, the EN 16185 series and the EN 15734 series. This European Standard also takes into account electrical and electronic control functions and additional brake systems like dynamic brakes and adhesion independent brakes. The brake system requirements, which are specific for on-track machines are set out in EN 14033-1. This European Standard does not apply to Urban Rail rolling stock braking system, which is specified by EN 13452-1.
