Low‑Adhesion Phenomena — Official Resources

• SNCF : Leaf Contamination & Rail Adhesion
  ‍Title : Fallen Leaves and Adhesion Loss
  SNCF explains that fallen leaves, combined with moisture, create a slippery organic film on the rail surface. This ‘vegetal paste’ drastically reduces wheel–rail adhesion and disrupts train operations, especially during the autumn season.

• SNCF Réseau : Preventing Adhesion‑Related Risks
  ‍Title : Adhesion and Safety Campaigns
  SNCF Réseau outlines the risks associated with wheel–rail adhesion loss and the operational disruptions it can cause. The company also details the safety and prevention campaigns implemented each year to manage low‑adhesion conditions, particularly during the autumn season when leaf contamination and moisture significantly affect rail performance.

How Railway Organizations and Institutions Address the Issue of Low Adhesion

Several major rail institutions actively address the issue of wheel–rail adhesion loss. The European Union Agency for Railways (ERA) integrates low‑adhesion scenarios into safety and braking performance requirements within its regulatory framework. The International Union of Railways (UIC) studies adhesion from a technical and operational perspective, publishing guidance on wheel–rail interaction, seasonal contamination, and mitigation practices. In the United Kingdom, the Rail Safety and Standards Board (RSSB) leads extensive research programs dedicated to low‑adhesion events, driver guidance, and testing of mitigation technologies. Together, these institutions recognize adhesion loss as a critical factor affecting safety, reliability, and operational performance.
