The Underload Toolbox
For many years, the rail industry has known that high mental or physical workload (overload) can cause people to make mistakes. However, there has been very little recognition of what happens at times when workload is low (underload).
RSSB conducted a research project to investigate possible mitigation strategies to counter cognitive underload in train drivers. This has led to the development of practical techniques that can be implemented by the GB rail industry.
