DIN EN 13803:2017-09

This European Standard (EN 13803, "Railway applications - Track - Track alignment design parameters - Track gauges 1 435 mm and wider") shall replace EN 13803-1:2010 and EN 13803-2:2006+A1:2009 and has been prepared by Technical Committee CEN/TC 256 "Railway applications", the secretariat of which is held by DIN. The purpose of this European Standard is to specify rules and limits for track alignment design parameters, including alignments within switches and crossings. Several of these limits are functions of speed. Alternatively, for a given track alignment, it specifies rules and limits that determine permissible speed. This European Standard applies to nominal track gauges 1 435 mm and wider with speeds up to 360 km/h. Normative Annex A describes the conversion rules which shall be applied for tracks with nominal gauges wider than 1 435 mm. Normative Annex B is applied for nominal track gauges 1 520 mm, 1 524 mm and 1 668 mm. This European Standard is also applicable where track alignment takes into account vehicles that have been approved for high cant deficiencies (including tilting trains). More restrictive requirements of Technical specifications for interoperability relating to the 'infrastructure' subsystem of the rail system in the European Union (TSI INF) and other (national, company, etcetera) rules will apply. This European Standard need not be applicable to lines, or dedicated parts of railway infrastructure that are not interoperable with railway vehicles tested and approved according to EN 14363. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive 2008/57/EC. The responsible German committee is Working Committee NA 087-00-01-07 UA "Trassierungsparameter" ("Track alignment") at DIN Standards Committee Railway (FSF). This standard differs from DIN EN 13803-1:2011-03 and DIN EN 13803-2:2010-06 as follows: a) the standards DIN EN 13803-1, "Railway applications - Track - Track alignment design parameters - Track gauges 1 435 mm and wider - Part 1: Plain line" and DIN EN 13803-2, "Railway applications - Track - Track alignment design parameters - Track gauges 1435 mm and wider - Part 2: Switches and crossings and comparable alignment design situations with abrupt changes of curvature" have been combined into DIN EN 13803.
