Introduction

Currently, in the standard gauge area, there are EU regulations in the form of interoperability directives and

the associated TSI that also contain specifications for the braking of railway vehicles. Before this time, brake

engineering regulations only existed as internal railway documents in the form of UIC leaflets.

Agreements based on these govern the conditions for vehicle transfers between the individual railways. The

relationship between the infrastructures and the minimum brake engineering requirements on trains and their

individual vehicles is defined in EN 14198.This covers mainly generic vehicle regulations that should be

assigned to individual vehicles by corresponding specifications.

With this European Standard, all suppliers will in future be able to offer in a Europe-wide tender invitation

passenger coaches that have a defined basic brake engineering system and meet the minimum brake

engineering requirements, taking into account the vehicle types

5 Requirements
5.1 General

The Railway Authorities shall include this European Standard as part of the requirements for the brake

installation. The manufacturers shall indicate in the tender where the requirements of the standard are not

met.

Vehicles as specified in this standard shall totally meet the relevant generic requirements described in

EN 14198 for the train and the resulting requirements for the individual vehicles.

These requirements are defined for the individual vehicle in the clauses:
 brake control;
 thermal capacity;
 brake performance;
 other brake components.

The specific requirements are allocated in vehicle classes. The specific brake systems mandatory for the

particular vehicle class are contained in Table A.1.
Each vehicle class is divided into subclasses for additional brake devices.
5.2 Climatic conditions

In general, the requirements of EN 50125-1 apply. The requirements listed below are minimum requirements.

The temperature class according to EN 50125-1 shall be specified by the Railway Authoritiy.

The functional ability of the brake shall be achieved under the following conditions unless deviations have

been agreed for the associated vehicle:
 outside temperature – 25 °C to + 40 °C (in sunshine up to + 70 °C);
 altitude up to 1 370 m above sea level;
 relative humidity up to 100 %;
 snowfall, lying snow up to 300 mm above top edge of rail;
 rain, ice;
 gusts of wind up to 30 m/s

The special climatic conditions in tunnels (e.g. Simplon up to 27 °C and 100 % relative humidity in winter also)

should be noted.
5.3 Brake control
5.3.1 Basic principles

The brake installation for each vehicle shall meet the requirements of the UIC brake system.

The basic system arrangement is shown in Figure H.1.
---------------------- Page: 13 ----------------------
SIST EN 15179:2008
EN 15179:2007 (E)

If other brake systems are used, the UIC brake system shall be subordinate as a pneumatic back-up brake

(safety level). With the UIC-type brake system, it is allowed to provide electro-pneumatic control support for

the BP.
The functional arrangement of the system is shown in Figure H.2.

The brake control system shall be able to provide the passenger train and goods train brake types and the

associated brake positions and have the standardized operating and indicating devices on the coach sides.

5.3.2 Components of the basic system

The components described in the following are brake components in the coach that are to be assigned to train

level 5 or vehicle level 6 in accordance with Figure H.2.
5.3.2.1 Air brake pipe (BP) and main reservoir pipe (MRP)

All vehicles shall be equipped with a continuous air brake pipe (BP) and a continuous main reservoir pipe

(MRP) in a bifurcated connection each with an inside diameter of at least 25 mm. The basic function of the

brake system (transmission of braking command and control function, energy supply) shall be possible via the

BP alone. The compressed air in the BP shall not be used for other purposes not related to the brake

installation.

The compressed air in the MRP can be used for supplying energy to other loads in the vehicle (door

operating, toilets, air springs etc.) in addition to supplying energy for the brake installation.

The air pipes shall be installed free of water collection pockets and be as straight as possible utilizing large

bend radii (minimum dimension for bend radius 5 × D = outside diameter). The bifurcation shall be achieved

by means of a Y-connection. Filters or other components that would reduce the cross-section of the BP shall

not be fitted. If low points are unavoidable in routing the pipes, easily accessible drainage devices shall be

fitted.

Free passage through BPs and MRPs shall be capable of being verified by means of a ball test. The diameter

of the ball to be used shall be 19 mm. Steel pipes used shall meet the requirements of EN 10220 or

EN 10305-4 or EN 10305-6.

The number of pipe fittings used shall be kept to a practical minimum and all fittings shall be accessible

without having to disassemble other equipment.
Connections consisting of threads on the pipes are not permitted.

The pipe connections at the coach end shall meet the UIC requirements. A recommended method of fitting is

described in 5.3.2.6. This takes account of the installation space for the end cocks and the space requirement

of other pipe connections also for the possible counter-movements of the vehicles to be coupled.

5.3.2.2 Controller

Every vehicle shall be equipped with at least one distributor valve which complies with the requirements of

prEN 15355. The maximum BP volume of 25 l shall be assigned to any distributor valve.

For connection into the coach brake system, the diagram illustrated in Figure H.2 of this European Standard

applies.

The controller indicated as item 10 is connected by its large pipe cross-section to the BP and is connected to

the E-store (reserve air tank (R-tank) and the devices generating the brake force thus allowing single-pipe

operation (operation without MRP). The supply to the energy store is from the BP through the controller.

---------------------- Page: 14 ----------------------
SIST EN 15179:2008
EN 15179:2007 (E)

Every controller shall be equipped with an isolation device that can be operated from both sides of the vehicle.

Every controller shall be equipped with one or more isolation devices that can be operated from both sides of

the vehicle. Operation of these devices shall isolate the controller from the brake pipe and the main reservoir

pipe and isolate any other brake related devices (e.g. track brake, etc.) from the main reservoir pipe. The

brake cylinders and the auxiliary reservoir shall then be vented, either automatically or manually using another

control device that can also be operated from both sides of the vehicle. Free passage of air through the BP

and MRP shall be maintained on that vehicle.

Every controller shall also be equipped with a device that allows the brake on that vehicle to be released when

it is applied (release valve).

Every controller shall be equipped with a mode switch for the selection of brake positions (e.g. G, P, R, R+Mg)

that can be operated from both sides of the vehicle.

Test points shall be fitted for the verification of the correct functioning of the controller; at least the output

pressure and the load- and speed-dependent pressures, e.g. brake cylinder pressures.

5.3.2.3 Energy store

Every controller shall be connected to an energy store so that energy can be fed from this store into the

devices generating the brake force when a brake command is given. The energy store shall be dimensioned

so that, when the brake is applied, the available brake power at each point in the train journey and for all track

conditions meets the requirements of the UIC

EN 15179:2007 (E) 4 Foreword This document (EN 15179:2007) has been prepared by Technical Committee CEN/TC 256 “Railway applications”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2008, and conflicting national standards shall be withdrawn at the latest by March 2008. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

EN 15179:2007 (E) 5 Introduction Currently, in the standard gauge area, there are EU regulations in the form of interoperability directives and the associated TSI that also contain specifications for the braking of railway vehicles.

Before this time, brake engineering regulations only existed as internal railway documents in the form of UIC leaflets.

Agreements based on these govern the conditions for vehicle transfers between the individual railways. The relationship between the infrastructures and the minimum brake engineering requirements on trains and their individual vehicles is defined in EN 14198.This covers mainly generic vehicle regulations that should be assigned to individual vehicles by corresponding specifications.

With this European Standard, all suppliers will in future be able to offer in a Europe-wide tender invitation passenger coaches that have a defined basic brake engineering system and meet the minimum brake engineering requirements, taking into account the vehicle types SIST EN 15179:2008

EN 15179:2007 (E) 6

1 Scope This European Standard defines basic requirements for the braking of passenger coaches in trains hauled by locomotives as described in EN 14198, using UIC air brakes (RIC traffic) operating on routes of the European railways and their infrastructure systems. Normative Annex E is provided for passenger coaches limited to internal use in the UK. This European Standard covers:

all new vehicle designs of the passenger coach type of construction (day coaches, restaurant cars, sleeper coaches, driving trailers, baggage cars, couchette coaches); ¾ all new constructions of existing vehicle types; ¾ other vehicles (e.g. motorail vehicles) that may also be included in passenger trains; ¾ all major overhauls of the above-mentioned vehicles if they involve redesigning or extensive alteration to the brake system1 of the vehicle concerned. The vehicles meet the following technical criteria: ¾ inclusion in trains in accordance with EN 14198 in regular railway operation is possible (coupling capacity); ¾ the maximum speed is between 100 km/h and 200 km/h; ¾ the lower vehicle limitations of prEN 15273-1, prEN 15273-2, prEN 15273-3

are adhered to.

EN 15179:2007 (E) 11 5 Requirements 5.1 General The Railway Authorities shall include this European Standard as part of the requirements for the brake installation.

The manufacturers shall indicate in the tender where the requirements of the standard are not met. Vehicles as specified in this standard shall totally meet the relevant generic requirements described in

EN 14198 for the train and the resulting requirements for the individual vehicles.

These requirements are defined for the individual vehicle in the clauses:

brake control; ¾ thermal capacity; ¾ brake performance; ¾ other brake components. The specific requirements are allocated in vehicle classes.

The specific brake systems mandatory for the particular vehicle class are contained in Table A.1. Each vehicle class is divided into subclasses for additional brake devices. 5.2 Climatic conditions In general, the requirements of EN 50125-1 apply.

The requirements listed below are minimum requirements.

The temperature class according to EN 50125-1 shall be specified by the Railway Authoritiy.

The functional ability of the brake shall be achieved under the following conditions unless deviations have been agreed for the associated vehicle:

outside temperature – 25 °C to + 40 °C (in sunshine up to + 70 °C); ¾ altitude up to 1 370 m above sea level; ¾ relative humidity up to 100 %; ¾ snowfall, lying snow up to 300 mm above top edge of rail; ¾ rain, ice; ¾ gusts of wind up to 30 m/s The special climatic conditions in tunnels (e.g. Simplon up to 27 °C and 100 % relative humidity in winter also) should be noted. 5.3 Brake control 5.3.1 Basic principles The brake installation for each vehicle shall meet the requirements of the UIC brake system. The basic system arrangement is shown in Figure H.1. SIST EN 15179:2008

EN 15179:2007 (E) 12 If other brake systems are used, the UIC brake system shall be subordinate as a pneumatic back-up brake (safety level). With the UIC-type brake system, it is allowed to provide electro-pneumatic control support for the BP. The functional arrangement of the system is shown in Figure H.2.

The brake control system shall be able to provide the passenger train and goods train brake types and the associated brake positions and have the standardized operating and indicating devices on the coach sides. 5.3.2 Components of the basic system The components described in the following are brake components in the coach that are to be assigned to train level 5 or vehicle level 6 in accordance with Figure H.2. 5.3.2.1 Air brake pipe (BP) and main reservoir pipe (MRP) All vehicles shall be equipped with a continuous air brake pipe (BP) and a continuous main reservoir pipe (MRP) in a bifurcated connection each with an inside diameter of at least 25 mm.

The basic function of the brake system (transmission of braking command and control function, energy supply) shall be possible via the BP alone.

The compressed air in the BP shall not be used for other purposes not related to the brake installation. The compressed air in the MRP can be used for supplying energy to other loads in the vehicle (door operating, toilets, air springs etc.) in addition to supplying energy for the brake installation. The air pipes shall be installed free of water collection pockets and be as straight as possible utilizing large bend radii (minimum dimension for bend radius 5 ´ Da = outside diameter).

The bifurcation shall be achieved by means of a Y-connection.

Filters or other components that would reduce the cross-section of the BP shall not be fitted.

If low points are unavoidable in routing the pipes, easily accessible drainage devices shall be fitted. Free passage through BPs and MRPs shall be capable of being verified by means of a ball test. The diameter of the ball to be used shall be 19 mm.

Steel pipes used shall meet the requirements of EN 10220 or
EN 10305-4 or EN 10305-6.

The number of pipe fittings used shall be kept to a practical minimum and all fittings shall be accessible without having to disassemble other equipment. Connections consisting of threads on the pipes are not permitted. The pipe connections at the coach end shall meet the UIC requirements. A recommended method of fitting is described in 5.3.2.6.

This takes account of the installation space for the end cocks and the space requirement of other pipe connections also for the possible counter-movements of the vehicles to be coupled. 5.3.2.2 Controller Every vehicle shall be equipped with at least one distributor valve which complies with the requirements of

prEN 15355.
The maximum BP volume of 25 l shall be assigned to any distributor valve.

For connection into the coach brake system, the diagram illustrated in Figure H.2 of this European Standard applies.

The controller indicated as item 10 is connected by its large pipe cross-section to the BP and is connected to the E-store (reserve air tank (R-tank) and the devices generating the brake force thus allowing single-pipe operation (operation without MRP). The supply to the energy store is from the BP through the controller.

SIST EN 15179:2008

EN 15179:2007 (E) 13 Every controller shall be equipped with an isolation device that can be operated from both sides of the vehicle.

Every controller shall be equipped with one or more isolation devices that can be operated from both sides of the vehicle.

Operation of these devices shall isolate the controller from the brake pipe and the main reservoir pipe and isolate any other brake related devices (e.g. track brake, etc.) from the main reservoir pipe. The brake cylinders and the auxiliary reservoir shall then be vented, either automatically or manually using another control device that can also be operated from both sides of the vehicle. Free passage of air through the BP and MRP shall be maintained on that vehicle. Every controller shall also be equipped with a device that allows the brake on that vehicle to be released when it is applied (release valve).

Every controller shall be equipped with a mode switch for the selection of brake positions (e.g. G, P, R, R+Mg) that can be operated from both sides of the vehicle.

Test points shall be fitted for the verification of the correct functioning of the controller; at least the output pressure and the load- and speed-dependent pressures, e.g. brake cylinder pressures. 5.3.2.3 Energy store Every controller shall be connected to an energy store so that energy can be fed from this store into the devices generating the brake force when a brake command is given.

The energy store shall be dimensioned so that, when the brake is applied, the available brake power at each point in the train journey and for all track conditions meets the requirements of the UIC brake system. The inexhaustibiity as defined in EN 14198 shall be achieved.

The energy store for pneumatically-operated brake systems shall also be fed from the MRP via filter, pressure-reducing valve, isolating cock and non-return valve.

The energy store for compressed air shall be in accordance with EN 286-3 and EN 286-4. Maintenance aspects are covered by UIC 541-07 or other applicable documents, e.g. DIN 5590 and DIN 5580.

Requirements of the energy stores for electrically-operated brake systems shall be according to UIC 550.

5.3.2.4 Passenger emergency brake and emergency brake override 5.3.2.4.1 Basic principles – system interfaces All passenger vehicles shall be equipped with a passenger emergency brake. The passenger emergency brake is located in the "Decentralized command initiation for automatic application of brakes" block (see EN 14198 and Figure H.1 of this European Standard) and on actuation of an operating element (emergency brake handle according to prEN 15327-1) initiates the triggering of an emergency brake valve and thus the activation of the automatic brake of the train. Automatic application of the brake at train level is initiated.

Activation of the automatic train brake by operation of an emergency brake handle shall also be possible with the vehicle brake isolated. When a passenger emergency brake handle has been operated, it shall be automatically locked in this position. An activated emergency brake becomes ineffective with the actuation by the train crew of the resetting device on the applied emergency brake box or activation of the EBO by the train driver in accordanc
