EN 16704-2-1:2016 (E) DIN EN 16704-2-1:2017-03 5 Introduction The purpose of this standard is to define the requirements for Track Warning S

28、ystems (TWS) used to warn people about approaching trains and rail vehicles when on or near the track during their work. TWS can be subdivided into the following types: LOWS Lookout Operated Warning Systems; ATWS Automatic Track Warning Systems; SCWS Signal Controlled Warning Systems. Each class can

29、 be used as a warning system by itself or with an additional function that can influence approaching trains and rail vehicles. For instance LOWS-I, ATWS-I or SCWS-I (-I: influence function). This standard defines minimum system requirements for TWS. EN 16704-2-1:2016 (E) DIN EN 16704-2-1:2017-03 6 1

30、 Scope This European Standard defines minimum functional and non-functional requirements for Track Warning Systems (TWS) used to warn persons about approaching trains and rail vehicles during their work on or near the track. These systems may also have an additional function that can influence the a

31、pproaching trains and rail vehicles. The influence could be a stopping, passing or other function. This European Standard is applicable to: systems, sub-systems and components within TWS, including those containing software; new TWS; new integrations of systems, sub-systems and components into exist

32、ing TWS; and modifications of TWS developed according to this standard. It is also recommended to use this standard for single warning units (e.g. simple electrical horns). This European Standard does not apply to the following items: hazards during the installation/removal of the TWS caused by trai

33、ns and rail vehicles on the lines; hazards caused by the improper use of TWS; hazards caused by the improper behaviour of persons working on or near the track; hazards caused by the (unauthorized) presence of persons on or near the track; CO2-horns (tyfons), human operated pressure signal horns, fla

34、gs, detonators or machine warning systems according to UIC 644; national safety regulations to plan and operate TWS in track. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
