This standard BS EN 13848-5:2017 - TC Tracked Changes. Railway applications. Track. Track geometry quality is classified in these ICS categories:

• 93.100 Construction of railways

This European Standard defines the minimum requirements for the quality levels of track geometry, and specifies the safety related limits for each parameter as defined in EN 13848-1 and measured by any track geometry measurement system as defined in EN 13848-2, EN 13848-3 and EN 13848-4. This European Standard covers the following topics: - immediate action limits (IAL); - recommendations on tolerance levels for isolated defects; - relative importance of parameters with respect to the vehicle behaviours. The necessity to measure, the frequency of measurements and the selection of measured parameters are not covered by this European Standard. This European Standard applies to high-speed and conventional lines, including switches and crossings, of 1 435 mm and wider gauge railways provided that the vehicles operated on those lines comply with EN 14363 and other vehicle safety standards. This European Standard does not apply to Urban Rail Systems.
