Railway applications - Braking - Requirements for the brake system of trains hauled by locomotives
This document 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 document 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 document does not apply to Urban Rail rolling stock braking system, which is specified by EN 13452-1.

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 256.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.
This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
