Improving driver action and reducing incidents by better delivery of adhesion information
One persistent problem the GB railway faces is low adhesion at the wheel-rail interface. Despite industry investing significant resources, low adhesion issues continue to have substantial financial and passenger disruption impacts.
These issues also affect train drivers’ behaviour, leading to decreased confidence, lower morale, and delays during the autumn season.
RSSB recognised the need to improve the information that drivers receive for low-adhesion conditions.
The project team engaged train and freight operating companies to assess the usability and usefulness of existing material for drivers to manage low-adhesion conditions.
The team collaborated with driver managers, trainers, and operations standards managers to gain insights.
They examined factors such as timing, formats used, management attitudes, and practices that could influence driver perceptions and behaviours.
To ensure a comprehensive understanding, the project team also engaged with a representative sample of drivers. They did this to evaluate how they perceive adhesion-related information, examine its practical use, and identify any barriers preventing implementation.
RSSB’s six driver adhesion principles will enhance the usability of adhesion information provided to drivers.
By adhering to these principles, adhesion information will become more accessible and user-friendly, contributing to improved decision making and driver confidence.
The principles emphasise the importance of providing clear messaging to ensure that drivers feel empowered and capable of effectively navigating challenges associated with low adhesion.
