The first Minimel Lynx systems with ALADIN (Automatic Level Adaption Due to Identified Noise) were delivered to our customers. The ALADIN effect is technically based on a control system. It controls the warning volume automatically depending on the ambient noise. The implemented technical solution ALADIN for Track Warning System provides the following benefits:

  • Redundant
    2 independent measurement paths allow a failsafe structure with SIL4

  • Accurate
    Microphones used as sound level meters are very accurate over the entire frequency and temperature range.

  • monitoring of the emitted warning level
    While the warning unit sounds the alarm, the controller supervises via the microphones the emitted warning level and recognizes unauthorized manipulation

  • Compliant with standards and regulations
    All requirements compliant to upcoming standard EN16704-2-1 and the DB module 132.10118 ragarding automatic level adjustments

For the neigboring residents of railway construction sites, ALADIN measurably reduces noise generated from the Track Warning System, without impairing the sound level to warn track workers. This contribution to environmental protection has been demonstrated on several test sites.

For the third year running, Schweizer Electronic will be exhibiting at Rail2015 on 16th/17th September 2015 at Long Marston. This open air event gives Schweizer an opportunity to showcase its Minimel Lynx system and fully demonstrate its capabilities as a flexible Track Warning System that can be configured to run fully automatically without lookouts.

The event itself, brings together the latest innovations in Rail and serves as an excellent environment for industry stakeholders to meet and encourage better cross-industry engagement throughout the supply chain.

The Schweizer Electronic stand is located in Zone L4.4. If you’d like to set up an appointment with a representative then please contact This email address is being protected from spambots. You need JavaScript enabled to view it. 

Schweizer Electronic manufactures Track Warning Systems serving Rail infrastructure companies across the world. Their products are designed to provide safe access to running rail for track workers, facilitating productive rail maintenance and construction techniques. The company’s latest product, Minimel Lynx, is a Lightweight Track Warning System which can be configured to operate without lookouts using a Radar Sensor to detect the train. In addition, the company produces Level Crossings and following a successful tender is trialling a new Enhanced User Worked Crossing with Network Rail.
