Railway applications - Methods for calculation of stopping and slowing distances and immobilization braking - Part 1: General algorithms utilizing mean value calculation for train sets or single vehicles; German version EN 14531-1:2015
Bahnanwendungen - Verfahren zur Berechnung der Anhalte- und Verzögerungsbremswege und der Feststellbremsung - Teil 1: Allgemeine Algorithmen für Einzelfahrzeuge und Fahrzeugverbände unter Berücksichtigung von Durchschnittswerten; Deutsche Fassung EN 14531-1:2015
Overview
This European Standard describes a common calculation method for railway applications. It describes the general algorithms utilizing mean value calculation for use in the design and validation of brake equipment and braking performance for all types of train sets and single vehicles. In addition the algorithms provide a means of comparing the results of other braking performance calculation methods. EN 14531 was originally planned to have six parts covering the calculation methodology to be used when conducting calculations relating to the braking performance of various types of railway vehicles under the heading EN 14531, Railway applications - Methods for calculation of stopping, slowing distances and immobilization braking. The six parts were as follows: - Part 1: General algorithms; - Part 2: Application to single freight wagon; - Part 3: Application to mass transit (LRVs and D- and E- MUs); - Part 4: Application to single passengers coach; - Part 5: Application to locomotive; - Part 6: Application to high speed trains. Following the above it was decided that a common methodology could be used for Parts 2 to 5 and this should be contained under a revised version of Part 1 with a title of Railway applications - Methods for calculation of stopping and slowing distances and immobilisation braking - Part 1: General algorithms utilizing mean value calculation for train sets or single vehicles while revising Part 6 to be Part 2 with the title of Railway applications - Methods for calculation of stopping and slowing distances and immobilization braking - Part 2: Step by step calculations for train sets or single vehicles. EN 14531-1:2005 and EN 14531-6:2009 are referenced in the current technical specifications for interoperability (TSIs) (Freight wagons and locomotive and passenger rolling stock (RST)). The tables of the Annex ZA give the equivalence of the TSI referenced clauses of the original EN 14531 series to the clauses of this issue of FprEN 14531-1 and FprEN 14531-2.
