Railway Warning Systems for Track Construction Sites

As the leading producer of warning systems for track construction sites, ZÖLLNER has been securing work sites and workers around the world for over 25 years. Be it the modern radio technology based system MRWS (GB2), the well-established and proven hardwired system Autoprowa, the signal controlled warning system, the temporary level crossing system, or a combination thereof – ZÖLLNER offers a solution for every track construction site.

While the modular make-up of all ZÖLLNER systems allows for maximum flexibility, the SIL-certified warning devices guarantee maximum safety. Equipped with the Autoprowa-Effect, all warning devices continuously measure the surrounding noise and adjust the volume level of the emitted warning signal accordingly. ZÖLLNER systems thus warn as loudly as necessary (in order for the warning signal to be heard over the surrounding construction noise) and as quietly as possible (in order to keep the noise pollution for the environment and civilians as minimal as possible).

Rail and Rolling Stock Product Portfolio:

  • Mobile Radio Warning System – MRWS
  • Hardwired (cable-based) Warning System
  • Signal Controlled Warning System
  • Temporary Level Crossing System
  • Speed Detection Unit
  • Machinery Warning
  • Audible Warning Devices – Warning horns for railway vehicles

Mobile Radio Warning System – MRWS (GB2)

Bidirectional technology that works over great radio ranges makes the MRWS a flexible and safe solution. The SIL 4 certified system can be set and ready within minutes making it suitable for worksites that are of short duration, are quickly moving, or require a flexible configuration that can be changed over the course of the works carried out. That transmitter can be manually activated by a lookout (LOWS – lookout activated warning system).Or activated by inductive sensors (SATWS – semi automatic track warning system). Fully automatic strike-out is possible as well (ATWS – automatic track warning system).

Hardwired (Cable-Based) Warning System

The ZÖLLNER hardwired (cable-based) railway warning system has proven its worth on worksites for over 20 years. Optimally configured for long worksites over longer periods of time (>1 week), the low-maintenance system offers maximum safety for all personnel working on or near tracks.

Signal Controlled Warning System

When using the signal controlled warning system, no installation of train detectors is necessary – the semi-permanently installed system simply picks up the required information from the interlocking system making it perfect for ongoing or recurring projects involving different people that may need to come and go.

Temporary Level Crossing System

The system TH-BÜP is suitable as a temporary level crossing or a replacement for a level crossing that is temporarily out of order. Controlled by the level crossing guard, the system resembles a regular level crossing which increases its acceptance among road traffic participants and thereby increases the level of safety significantly compared to other methods used to secure temporary crossings. The modular concept makes for tailored solutions that allow the securing of any crossing situation.

Speed Detection Unit

In order to prevent track vehicles from moving too fast where reduced speeds are necessary, the speed detection unit measures the actual speed of a track vehicle before triggering a forced brake to slow the vehicle. By always measuring the actual speed rather than relying on calculated data, the system avoids unnecessary forced brakes in order to prevent possible resulting dangers for travelling passengers.

Audible Warning Devices – Warning Horns for Railway Vehicles

For over 75 years, ZÖLLNER has been building compressed air-driven signal horns for rail vehicles. Thanks to these many years of experience, we have acquired superior knowledge that makes us a reliable partner for vehicle manufacturers.

Today our product portfolio for rail vehicles includes a large selection of signal horns with different frequencies. We place particular emphasis on compliance with increasing requirements for materials (REACH, ROHS EN45545 etc.), documentation and safety.

Developing individual solutions and modifying products together with our customers and partners is one of our passions.

With our new EM660/370 TSI electric Makrofon, we are offering a signaling solution that is independent of compressed air.
