Safety in Rail Systems: Traction Sand Against Icing and Slipping
In train, tram, and other railway transport operations, one of the biggest risks is harsh weather conditions. Particularly precipitation, leaves on the track, and frost events dangerously reduce the frictional force (adhesion) between the wheel and the rail.
This situation leads to potential icing and slipping, causing both an uncontrolled extension of braking distance and wheel spin (patinage) during startup.
Solution: Rail Sanding Systems
To close this critical safety gap, locomotives and trams are equipped with automatic sanding systems. These systems;
- During acceleration or sudden braking,
- Just in front of the point where the wheels contact the rail surface,
- Spray specially qualified silica sand (traction sand) at high pressure.
This sprayed sand instantly creates a dry and rough surface between the wheel and the rail, maximizing traction. This ensures safe operation and safe stopping distances in railway transport, regardless of weather conditions.
