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.

Overview

EN 14198:2016+A1:2018/prA2 (CEN) defines essential brake system requirements for trains hauled by locomotives. The standard ensures interoperability by requiring a traditional brake pipe compatible with the UIC brake system for general-operation trains, and it sets vehicle and train-level requirements for fixed/predefined formations. EN 14198 also covers electrical/electronic control functions and additional brake types such as dynamic brakes and adhesion-independent brakes. Urban rail braking systems are excluded (see EN 13452‑1), and on-track machine brake specifics are handled in EN 14033‑1.

Key topics and technical requirements

• UIC brake compatibility: Vehicles intended for general operation must provide a brake pipe compatible with the UIC brake architecture to ensure cross-origin train braking interoperability.
• Fixed-formation requirements: Trains in fixed or predefined formations are subject to additional vehicle- and train-level criteria; where a UIC brake system is not used, EN 16185 or EN 15734 series apply.
• Electrical/electronic control: The standard addresses integration of electrical and electronic brake control and train protection interfaces.
• Additional brake systems: Includes guidance for dynamic brakes and adhesion-independent systems as part of the train braking concept.
• Amendment A2 - Annex F (normative): Introduces mandatory requirements and a test method for the venting performance of emergency valves used as safety equipment or by train protection systems:
  • Venting capacity is measured as the time from an emergency demand to a 1.5 bar pressure drop in a 400 L reservoir mounted at the brake-pipe extremity.
  • For each emergency-demand type, the 1.5 bar drop must be achieved within 3.9 seconds.
  • Test setup specifies a 400 L reservoir connected by a flexible hose (32 mm internal diameter, 5 ± 0.5 m length) and requires testing of the worst-case valve configuration.
• Braking performance limits (edits in Table A.1): Clarifications and numeric updates include a maximum mean retardation force of 16.5 kN per axle at 100 km/h, and braked weight limits (e.g., 15.25 t per wheelset), with conditional allowances for certain wagons up to 120 km/h subject to wheelset load and brake type.

Applications and users

Who uses EN 14198:

• Rolling-stock designers and OEMs specifying locomotive-hauled train brake systems
• Railway operators and infrastructure managers ensuring cross-fleet compatibility
• Signalling and train-protection engineers integrating emergency brake functions
• Test laboratories performing venting and emergency-valve certification Practical uses:
• Ensuring UIC brake interoperability across multi-origin consists
• Specifying emergency valve performance to meet stopping-distance and safety requirements
• Defining compatibility rules for integrating dynamic/distributed braking and electronic controls
