More safety on the track

Safety technology by HPZ for track construction sites

When working on railway tracks, personnel have to be protected from the dangers of railway operations. The best measure is, of course, to close the track. However, since a track closure is not always possible, HPZ GmbH offers a solution – e.g. with the fixed barrier UPZ III EN – which separates the workers from railway operations and thereby offers the highest degree of safety and protection. Moreover, HPZ GmbH allows you to benefit from technical aids to support crossing points, electrical signallers, the signalling of speed restrictions and much more. HPZ GmbH thus delivers the highest safety standards for protecting track construction sites.


  • Fixed barrier FA UPZ III

    The fixed barrier FA UPZ III EN is certified according to the requirements of DIN EN 16704-2-2 and the DB specification sheet for fixed barriers, version 1.1, dated 1 March 2020 and is approved for use on DB Netz AG infrastructure with the technical railway approval dated 31 October 2020.

  • Technical aid for crossing points (TH-BÜP UPZ) with integrated warning system

    The TH-BÜP is a transportable, easy-to-install barrier system with a level crossing sign and integrated traffic light system for supporting crossing points, without auxiliaries. Using the TH-BÜP, it is possible to quickly secure crossing points at which permanently installed safety systems are temporarily disabled due to construction work. The TH-BÜP replicates the function, design and appearance of a permanently installed safety system. Thanks to digital control technology, the TH-BÜP offers extension and integration options according to the concept of Industry 4.0.  Approval including warning system.

  • Barrier strap

    The barrier strap was developed as a durable alternative to conventional products available on the market. It is distinguished by high-performance elastomer that contracts the barrier strap to 20% of the nominal length. Continuous pretensioning prevents contact with the ground and significantly extends the lifespan. Weatherproof and washable contrast fabric and reflective material are used in alternating intervals of 500 mm. Our reflective material, which exceeds the highest performance level of the required minimum reflection values, reflects light in white. The angle of incidence has no effect on the colour reflected. Extra-large aluminium carabiners enable easy installation of the barrier strap.
