CLC/SC 9XB - Electromechanical material on board rolling stock

Add the following note after the paragraph in 1.6: 'NOTE This document was derived from the signalling standard EN 50128 which in many cases was also applied in Rolling Stock applications. Subclause 1.6 ensures continuity in the application of the standards, i.e., software that was developed in accordance with EN 50128 can still be re-used for new projects.'

The purpose of this document is to support rolling stock procurement, especially life cycle cost (LCC) assessment. This document is applicable to the specification and verification of energy consumption of railway rolling stock. It establishes a criterion for the energy consumption of rolling stock to calculate the total net energy consumed, either at current collector or from the fuel tank, over a predefined service profile, to ensure that the results are directly comparable or representative of the real operation of the train. For this purpose, this document considers the energy consumed and regenerated by the rolling stock. The determination methods covered are the simulation and the measurement. This document provides the framework that gives guidance on the generation of comparable energy performance values for trains and locomotives on a common basis and thereby supports benchmarking and improvement of the energy efficiency of rail vehicles. This document does not cover the comparison of energy consumption with other modes of transportation, or even for comparison between diesel and electric traction, covering only the energy consumption of the railway rolling stock itself.

This European Standard applies to electrical systems on board of vehicles of the type trolleybus, as defined in 3.1, fed with a nominal line voltage (Un) between 600 V d.c. and 750 V d.c. This European Standard defines the requirements and constructional hints, especially to avoid electrical danger to the public and to staff. Where special requirements are existing for trolleybuses, hints are given for mechanical and functional safety as well as for protection against fire. This European Standard covers vehicles intended for public transport of persons.

Application programming comprises high level programming, low level programming and special purpose programming (for example: programmable logic controller ladder logic). 1.5 This European Standard also addresses the use of pre-existing software and tools. Such software may be used, if the specific requirements in 7.3.4.7 and 6.5.4.16 on pre-existing software and for tools in 6.7 are fulfilled. 1.6 Software developed according to a valid version of EN 50128 is considered as compliant to this standard. Software previously developed in accordance with any version of EN 50128 is also considered as compliant and not subject to the requirements on pre-existing software. SIL1-SIL4 software developed under EN 50657 also complies with EN 50128:2011. 1.7 This European Standard considers that modern application design often makes use of software that is suitable as a basis for various applications. Such software is then configured by application data for producing the executable software for the application. This European Standard applies to such software. In addition, specific requirements for application data will be given. 1.8 Entry intentionally left empty 1.9 This European Standard is not intended to be retrospective. It therefore applies primarily to new developments and only applies in its entirety to existing systems if these are subjected to major modifications. For minor changes, only 9.2 applies. However, application of this European Standard during upgrades and maintenance of existing software is recommended. 1.10 The relevant sections of this software standard are also applicable to programmable components (e.g. FPGA and CPLD), in addition to the applicable hardware standard (e.g. EN 50129, EN 50155, EN 61508 2). However, requirements of this software standard that are already covered by the applicable hardware standard do not need to be re-addressed. When it is possible to exhaustively test the programmable logic for all possible inputs and internal logic states, this European Standard does not apply.

This European standard defines, for the purpose of ensuring compatibility between rolling stock and axle counter systems, the measurement and evaluation methods of rolling stock emissions to demonstrate compatibility. The established limits for compatibility are defined as magnetic field strength that can disturb the axle counter detectors, as part of the axle counter system. In the relevant frequency range of the axle counter detectors the magnetic field is dominant and only this type of field is considered. Experience has shown that the effects of electric fields are insignificant and therefore not considered. For axle counters systems whose limits are not defined in terms of magnetic fields at a detector level, National Rules apply where they exist. NOTE The influence from metal parts or inductively coupled resonant circuits on the vehicle, eddy current brakes or magnetic brakes is out of the scope of this EN. Compatibility is established through individual testing according to the EN 50238 series or National Notified Technical Rules.

This Technical Specification defines characteristics and interfaces for electric onboard power supply systems. It applies to locomotive hauled passenger trains and electric multiple units with distributed power as well as trains with concentrated power for main-line application. The objective of this Technical Specification is to define target systems, as regards the following interfaces and characteristics in order to enable further standardisation: • interface between traction system and auxiliary power supply system; • train line type: voltage, frequency and number of poles; • interface between auxiliary power supply system and battery system; • interface of the auxiliary power supply system as well as the low voltage grid to a shore supply (stationary workshop supply or external supply); • supply concepts for essential loads e.g. HVAC systems and battery chargers; • redundancy concept within the supply systems; • auxiliary load control and protection strategy at train level. Described system and interface characteristics define the technical basis for dependent European Standards and Technical Specifications. The introduction of this Technical Specification shows this dependency to adjacent documents. Starting from a generic functional description of electric onboard energy supply systems structured in line with EN 15380 4 and a description of the related vehicle concepts, generic system architectures are derived, which are illustrated by examples of consistent sets of system designs showing interfaces and dependencies among concerned subsystems. Relevant train configuration and concerned energy supply subsystems in scope of this Technical Specification are defined in Clause 4.

This Technical Specification defines the classification of the electric onboard auxiliary power converter system and defines its basic characteristics and interfaces. The onboard auxiliary power converter system consists of the auxiliary converter and the battery charger function. This Technical Specification applies to locomotive hauled passenger trains and electric multiple units with distributed power as well as trains with concentrated power heads. Relevant train configuration and concerned energy supply subsystems are defined in CLC/TS 50534. This Technical Specification provides a technical base for implementation of onboard auxiliary power systems on different trains.

This Technical Specification covers requirements for electric pumps which generate the circulation of insulation liquid in traction transformers and reactors of rail vehicles and their associated cooling system. The pumps covered by this Technical Specification are rotodynamic pumps driven by a squirrel cage induction motor which is immersed in the insulating liquid. CLC/TS 50537-2 gives consideration to both technical and normative requirements of the railway environment and restricts the variety provided by industry-wide standards for pumps (for example EN 50216-7 and EN ISO 9906). It determines requirements and tests enabling the interchangeability especially regarding electrical, mechanical and hydraulic interfaces. Furthermore, service conditions are described.

This Technical Specification covers requirements for centrifugal and peripheral electric pumps which generate the circulation of cooling liquid in converters of rail vehicles and their associated cooling system.

This Technical Specification covers gas and liquid actuated (Buchholz) relays for liquid immersed transformers and reactors with conservator for rail vehicles. The device is intended to detect • gas release from the unit to be protected, • cooling liquid surge from the protected unit to the conservator, • complete loss of the cooling liquid in the conservator. This Technical Specification gives consideration to both technical and normative requirements of the railway environment and restricts the variety in particular provided by the industry-wide standard EN 50216-2. It determines requirements and tests enabling the interchangeability of Buchholz relays by defining the following types of interfaces: • mechanical interface, e.g. flanges for pipe connection, dimensions; • electrical interface, e.g. supply voltage for making and breaking capability; • functional interface, e.g. protective operational behaviour. It is not applicable to flameproof relays. Different liquids may be used, which are typically used for both cooling and insulating. Furthermore, operating conditions are described.

This Technical Specification is applicable to high voltage (HV) bushings, intended for use in traction transformers of rail vehicles, cooled by insulating liquid with rated voltages up to 25 kV single phase and rated currents up to 630 A at frequencies from 16,7 Hz to 60 Hz. HV bushings within the scope of this Technical Specification are bushings for separable connectors that connect the power supply coming from a contact wire or from a contact rail to the primary winding of the traction transformer. The Technical Specification only deals with HV bushings that are mounted to the transformer. CLC/TS 50537-1 gives consideration to both technical and normative requirements of the railway environment and restricts the variety provided by industry-wide standards for bushings, such as EN 50180 and EN 60137. It determines requirements and tests enabling the interchangeability especially regarding electrical and mechanical interfaces. Furthermore, service conditions are described. The cable plug as the counterpart of the HV bushing’s plug-in end is not covered by this Technical Specification.

This Technical Report will define - requirements for the methods to be used for functional standardisation, in the standards to be prepared for data exchange involving railway vehicles, in two contexts 1) inter-consists communication, within a train formation, 2) communication with ground based installations. - the Reference Architecture defining the essential functional interfaces, - the concept of a central Data Dictionary/repository to be applied to freight and passenger traffic functions. In this context, data are to be limited to basic information elements, which are necessary to define standard messages required for interoperability, and displayed on the interfaces of the communicating entities. Entering Data Dictionary will provide full definition of a data element, along with its essential attributes at conceptual level. The purpose, in the perspective of the standards to be prepared, is to document the data element pertinent to the functional area and essential for interoperability, to allow the reuse of data element among functional area systems, and facilitate data interchange among the systems. NOTE Data Dictionary shall be designed to provide a structural framework that enables continued growth and enhancement of the scope of defined data. Rationale for this requirement is that it is difficult, when defining the scope of a proposed system to fully define the application domain and all included interoperability related data. In addition over time, functional requirements will expand.

States the characteristics of the resistors; the service conditions with which the power resistors have to comply; the tests intended for confirming that these conditions have been met and the methods to be adopted for these tests; the information to be marked on, or given with, the resistors. The object of this standard is to adapt the general rules given in IEC 60077-1 to power resistors for rolling stock in order to obtain uniformity of requirements and tests throughout the corresponding range of components and to avoid the need for testing to two different standards.
