Turnouts in Extreme Environments

Specific Technological Solutions for Desert Areas

At Vossloh, we are committed to enabling green mobility, even in the harshest environments. Our Turnouts in extreme environments are designed specifically to address the unique challenges presented by desert regions.

Customized Designs for the Harshest Environmental Conditions

Switches and crossing turnouts, along with their subsystems (actuation, locking, and detection), play a crucial role in maintaining traffic safety regardless of the environmental conditions. In desert areas, factors such as sand, high temperatures, and extreme sun exposure must be considered to ensure smooth operational efficiency.

With extensive experience as a network supplier in the most demanding environments, Vossloh has developed effective solutions to combat these challenges. Our innovative designs minimize the impact of sand buildup and employ components resistant to the effects of extreme temperatures and solar radiation.

Maneuvering Devices Tested in Laboratory

Our commitment to safety and reliability is backed by rigorous testing. A wind tunnel test was performed to evaluate the performance of our maneuvering devices in sand-filled wind conditions. Conducted in a CSTB wind tunnel (ISO and COFRAC certified laboratory), this test adheres to stringent standards (DEF-STAN 0035, MIL-STD 810 F, GAM EG 13) to simulate the extreme conditions of a sandstorm.

During the test, 3 tons of sand particles (20 to 200 µm) were projected for four hours, ensuring that our maneuvering devices operated without any locking or detection failures, even under the most severe conditions.

Suitable Solutions to Resist the Greatest Constraints

Switches and Crossings with Exclusive Technology

  • Maintenance-Free (Lubrication-Free) Switches and Crossings
    Our slide chairs are designed with advanced coatings (Cogislide or Nickel Chrome) that eliminate the need for lubrication, while rodings come fully equipped with treated shafts requiring no lubrication.
  • Enhanced Sand Evacuation
    Modifications include adding grooves to slide chairs and machining switch blade feet to facilitate sand evacuation.
  • Temperature Adaptability
    Thermal expansion devices are customized to withstand significant ambient variations (-18°C to +58°C).
  • Anti-Creeping System
    This innovative system limits the relative movement of components, ensuring stability and reliability.
  • Reinforced Switch Blade Tips
    Reinforcement is provided to switch blade tips to reduce additional wear caused by sand during wheel operations.

Point Operating Equipment Systems Conforming to Local Conditions

  • Optimized Point Operating Equipment
    Our switch locking devices have a reduced number of components to ease maintenance and improve sand clearing.
  • Proven Components
    We utilize reinforced motors and controllers that are specifically designed for sand sealing.

Proven Solutions Across Various Desert Regions

Our solutions have been successfully implemented in numerous countries with desert areas, including Algeria, Saudi Arabia, Australia, Egypt, Jordan, Mali, Morocco, Mauritania, Syria, Tunisia, and the UAE. Leveraging nearly 150 years of worldwide experience, Vossloh is dedicated to developing innovative solutions that prioritize optimal safety and significantly extend equipment life under the toughest environmental conditions.
