Braking distance 1 bar = 105 N/m2 = 105 Pa = 10-1 MPa 5 Design principles 5.1 General requirements 5.1.1 Safety Braking systems shall conform to the following: a) the braking performances defined in Clause 6; b) the design principles listed in the document below; c) the design principles listed in relevant standards on brake systems; d) the requirements for the operator using and maintaining the brake system in the intended manner;
e) keeping within the required limits, in order to reduce the effects on the track, as specified in 5.1.9 and 5.5. In the course of the system design the following risks shall be considered and mitigated. As a minimum, the following hazards shall be taken into account:
f) the brake force applied is greater than the level of brake demanded: 1) impact on standing passengers; NOTE No limits are so far defined to secure passengers, only reference could be made to the TSI requirement considering longitudinal forces which corresponds to 2,5 m/s². 2) excessive jerk; 3) significant damage to the contact surface of the wheels; g) the brake performance is lower than the level of brake demanded: 1) keeping traction effort on the whole train while emergency brake is requested; 2) emergency brake performance not achieved;
3) parking brake: performance not achieved; 4) holding brake for brake test not achieved; h) there is no brake force, when demanded: 1) emergency brake not activated on the whole train when requested; SIST EN 15734-1:2011



EN 15734-1:2010 (E) 10 2) automatic (emergency) brake not initiated in the case of an unintended train separation (loss of train integrity); 3) parking brake: loss of performance over the time; i) there is a brake force when a brake demand has not been made: 1) undue local brake application; 2) locked axle not detected; j) brake component failures that could cause death or injury to personnel or damage to the train or infrastructure, e.g. derailment. The hazards in this list shall be assessed in accordance with EN 50126-1.
Concluding from the hazards listed above the emergency brake shall have a high level of integrity and shall always be available when the brake system is set up for operation, whereas the service brake, whilst it may share subsystems and components, etc. with the emergency brake, need not achieve the same level of integrity. Nevertheless the service brake shall be designed to conform to the following requirements: k) the service brake shall be activated on the whole train when requested; l) in the case of a loss of service brake efficiency and: 1) if detected by the driver there shall be a means available for the driver to immediately apply the emergency brake by using the same lever which is used for service braking; 2) if the driver fails to detect a loss of efficiency then the train protection system (technical intervention system) shall have access to an emergency brake application; m) cut off traction effort on the whole train while service brake is requested; n) provide service brake effort at the level requested. High-speed trains incorporate a speed control system functioning with different deceleration levels. The prescribed performance levels defining the minimum braking power for trains suitable for running on all high-speed lines are given in Clause 6. The compliance of these performance levels and the safety of the braking system shall be fully demonstrated as specified in EN 15734-2. Accepted benchmark safety level for a brake system is the UIC-architecture as described in EN 14198. It is characterized by the following items: o) a continuous, automatic and inexhaustible brake system;
p) the medium is compressed air with its favourable properties; q) an energized (pressurized to release) brake pipe;
r) decentralized brake actuators, developing the brake force; s) proven design components. The components used shall withstand during their period in service any normal or exceptional stresses that have been specified. The safety implication of any failures shall be limited by appropriate means; as described in this standard. SIST EN 15734-1:2011



EN 15734-1:2010 (E) 11 Single point failures shall not cause any relevant malfunctions regarding emergency brake application. That means: t) functions at train level (in the sense used in EN 14198) shall be designed low active; u) functions at train level shall provide redundancy or a back up function for any electrical command chain applying the emergency brake; v) the man machine interface shall provide at least two separate means for demanding an emergency brake application; w) malfunctions on vehicle level (in the sense used in EN 14198) could be tolerated if the loss of a local function is limited to an acceptable effect by means of a sufficient quantity of units in the train. The acceptance criteria is defined by a reduced deceleration level as specified under degraded mode conditions “B” in the TSI as well as in Clause 6 in this document. Further reductions in the deceleration level are only tolerable when the probability of its occurrence is sufficiently low. At least, a qualitative examination shall be carried out.
