Every day, rail networks lose performance, safety margins, and millions in operational costs because of one invisible enemy : environmental deposits.
Leaves, sand, dust, humidity, pollution — they accumulate before the wheel touches the rail, creating a slippery, unstable surface that no existing solution truly prevents.
AirflowRail changes the equation.
We introduce a breakthrough :
a 100% passive, aerodynamic device that uses the train’s own movement to clean and stabilize the wheel–rail interface before contact occurs.
• No energy
• No electronics
• No maintenance
• Just physics — optimized
Environmental deposits cause a cascade of operational issues:
Direct Effects
• Loss of adhesion
• Wheel slip and slide
• Longer braking distances
• Reduced traction
Operational Consequences
• Delays, cancellations, and degraded punctuality
• Increased safety risks and operational incidents
• Higher energy consumption
• Premature wear of wheels, rails, and exposed components
• Rising maintenance costs
• Damage to brand reputation
Railway operators know the problem.
Until now, they simply lacked a preventive solution.
Today’s methods are mostly reactive:
• Frequent cleaning of tracks and rolling stock
• Rail and wheel reprofiling
• Costly active systems (sensors, sprayers, electromechanical devices)
• Chemical treatments with environmental impact
• Heavy mechanical protections
• High labour requirements
Their limitation is fundamental:
they act after the wheel–rail contact — too late to prevent adhesion loss.
AirflowRail Innovation introduces a compact, lightweight tube with an optimized aerodynamic profile.It transforms the natural airflow generated by the train into a directed, stabilizing jet that protects the wheel–rail interface.
How It Works
1- Natural airflow capture
The device intercepts part of the airflow generated by the moving train.
2- Optimized internal geometry
The tube shapes this airflow into a stable, controlled stream.
3- Redirection to critical zones
The airflow prevents deposits from settling and reduces the formation of slippery films.
4- Action upstream of the wheel–rail contact
This is the breakthrough:
the device prepares the rail surface before the wheel arrives.
5- Operational impact
• Improved adhesion
• Fewer slip/slide events
• Lower energy consumption
• More reliable operations
• Reduced maintenance needs
• All without consuming a single watt and without altering the ballast.
• Improved adhesion
Cleaner rail → better traction → lower energy use.
• Higher operational performance
Fewer disruptions, fewer losses, more reliability.
• Reduced environmental deposits
Leaves, sand, dust — significantly less accumulation.
• Zero energy, zero electronics
A passive, robust, long‑life solution.
• Lower maintenance costs
Less wear, fewer interventions, fewer failures.
• Universal compatibility
Works in humid, desert, industrial, and temperate environments.
• Easy integration
Suitable for:
- new rolling stock
- retrofitting existing fleets
• Humid climates (Europe, North America)
Leaves, moisture, biofilm → adhesion loss.
• Desert regions (Middle East, North Africa)
Sand and fine dust → slipping and abrasion.
• Industrial zones
Metallic dust and chemical residues → persistent deposits.
• High‑speed lines
High sensitivity to adhesion variations.
• Urban and regional lines
Frequent stops → traction becomes critical.
AirflowRail Innovation delivers what the rail industry has been missing:
a preventive, passive, and scalable solution to a global operational problem.
• Efficient
• Economical
• Ecological
• Compatible with every network.
AirflowRail continues to pioneer new applications in airflow management, energy efficiency, and railway safety — shaping the future of rail mobility.
