What is BS EN 16704-2-1 - Technical requirements for Track Warning Systems (TWS) about?
BS EN 16704-2-1 defines minimum functional and non-functional requirements for Track Warning Systems (TWS) used to warn people 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 approaching trains and rail vehicles. The influence could be a stopping, passing or other function.
Note1: BS EN 16704-2-1 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 existing TWS; and
- Modifications of TWS developed according to BS EN 16704-2-1
Note2: BS EN 16704-2-1 is also recommended to use this standard for single warning units (e.g., simple electrical horns).
Note3: BS EN 16704-2-1 does not apply to the following items:
- Hazards during the installation/removal of the TWS caused by trains 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, flags, detonators, or machine warning systems according to UIC 644
- National safety regulations to plan and operate TWS in track
Who is BS EN 16704-2-1 - Technical requirements for Track Warning Systems (TWS) for?
BS EN 16704-2-1 on technical requirements for Track Warning Systems (TWS) is useful for:
- Railway management authorities
- Infrastructure managers
- Site supervisors
- Inspection and testing department in railways
- Train operator companies (TOCs)
Why should you use BS EN 16704-2-1 - Technical requirements for Track Warning Systems (TWS)?
Track Warning Systems (TWS) detect trains in a wide variety of different layouts and guarantee timely and appropriate collective and/or individual signaling.
The purpose of BS EN 16704-2-1 is to define the requirements for Track Warning Systems (TWS) used to warn people about approaching trains and rail vehicles when on or near the track during their work.
BS EN 16704-2-1 provides technical requirements that can help during the manufacturing of the track warning system which can ensure timely signal and the reliability of the product that will save the workers from the approaching trains.
