Railway applications - Track - Safety protection on the track during work - Part 1: Railway risks and common principles for protection of fixed and mobile work sites

This European Standard defines minimum functional and non-functional requirements for developing a Track Warning Systems (TWS) to warn persons during their work on or nearby the track about the approaching of trains or rail vehicles using acoustical and visual TWS-Signals. These systems may also be able to influence the approaching of trains and rail vehicles by stoppage function. This European Standard is applicable: - to systems, sub-systems and components within TWS, including those containing software; in particular; - to new TWS; - to new integrations of systems, sub-systems and components into existing TWS; - to modifications of TWS developed according to this standard. For single warning units (e.g. simple electrical horns) it is recommended to use this standard, too. This document does not deal with: - hazards during the installation of the TWS caused by trains or rail vehicles on the lines; - hazards caused by the improper use of TWS; - hazards caused by the improper behaviour of persons working on or nearby the track; - CO2-tyfone, human operated pressure signal horn
