45.020 - Railway engineering in general

The present document specifies technical characteristics and methods of measurements for radio transmitters and
receivers used in the Euroloop communications system. The system is used in railway systems.
The present document applies to the following equipment:
1) The On-Board Equipment (OBE) transmitting the tele-powering to wake-up the Trackside Equipment and
receiving the Euroloop signal. The OBE comprises a receiver fitted with a dedicated antenna.
2) The Trackside Equipment receiving t...view more

Unchanged with respect to the current edition EN 50128:2011.
Scope of the amendment:
- Alignment with EN 50126-1:2017, EN 50126-2:2017 and EN 50129:2018 together with minor corrections

This document specifies the concepts and basic requirements for the planning of railway operation in order to reduce risk in the event of earthquakes. This excludes regions where the consequences of seismic hazard for railway operation are low or non-existent. The definition of such regions is out of the scope of this document. NOTE The stages defined for consideration of the countermeasures necessary for the safe management of the seismic hazards can also be relevant for dealing with other natu...view more

This European Standard applies to emission and immunity aspects of EMC for electrical and electronic apparatus and systems intended for use in railway fixed installations for power supply. This includes the power feed to the apparatus, the apparatus itself with its protective control circuits, trackside items such as switching stations, power autotransformers, booster transformers, substation power switchgear and power switchgear to other longitudinal and local supplies.

This document specifies the methodologies for calculation of braking performance for railway rolling stock. This document describes the general algorithms/formulae using instantaneous value inputs to perform calculations of brake equipment and braking performance, in terms of stopping/slowing distances, braking power and energy for all types of rolling stock, either as vehicles or units. The calculations can be performed at any stage of the assessment process (design, manufacture, testing, verif...view more

This European standard is applicable to safety-related electronic systems (including subsystems and equipment) for railway signalling applications.
This European standard applies to generic systems (i.e. generic products or systems defining a class of applications), as well as to systems for specific applications.
The scope of this European standard, and its relationship with other CENELEC standards, are shown in Figure 1.
This European standard is applicable only to the functional safety of ...view more

This document provides guidance on railway project planning for decision making. This document explores the key points of railway project planning, based upon the principles of ISO 21500, by incorporating characteristics specific to railway projects. This document covers: — the characteristics of railway projects; — stakeholders and their needs/interests; — conditions; — the definition of each process in a railway project; — key points of planning process; — correlation and causality among princ...view more

This document provides additional information to assist the understanding and the use of ISO 20138-1. The calculations in this document follow the same principles but they are slightly different. This document contains country specific calculation approaches currently in use and represents the state of knowledge including for calculating: — stopping and slowing distances; — equivalent response time; — brake performance; — brake ratio.

This document specifies methodologies for calculation of braking performance for railway rolling stock and is applicable to all countries. This document describes the general algorithms/formulae using mean value inputs to perform calculations of brake equipment and braking performance in terms of stopping/slowing distances, stationary braking, power and energy for all types of rolling stock, either as single vehicles or train formations, with respect to the braking distance. The calculations can...view more

This Technical Report is covering the description of the pantograph system and the functional
interface between the pantograph system itself and the TCMS, including the context of multiple units.
The pantograph system contains the pantograph and the pantograph control. The internal interface
between pantograph and pantograph control is not in the scope of this document.
