Health, Safety, and Wellbeing are central pillars of the Rail industry. Our network carries millions of passengers each day and relies on thousands of skilled workers performing safety-critical roles around the clock. From drivers and signallers to maintenance engineers and operations staff, the railway depends on peak human performance at every level.
In recent years, fatigue management has emerged as one of the most pressing safety issues facing the railway. Regulators, operators, and safety bodies increasingly recognise that tired staff can present a genuine operational risk, particularly in roles where alertness, concentration, and rapid decision-making are essential.
Though the industry has made considerable progress in improving safety culture over the past two decades, fatigue remains a complex challenge shaped by working patterns, lifestyle factors, and the inherent demands of a 24-hour railway.
The hidden hazard
Unlike many traditional safety hazards, fatigue is difficult to measure and even harder to control. It does not appear in the same way as a faulty signal or damaged track, yet its effects can be just as serious.
When a person becomes fatigued, reaction times slow, attention wanders, and decision-making becomes impaired. In safety-critical environments such as railway operations, this can increase the likelihood of human error. Microsleeps, which are brief, involuntary episodes of sleep lasting just a few seconds, are particularly concerning in transport settings, as they can occur without warning.
The Office of Rail and Road (ORR) has repeatedly highlighted fatigue as a key human-factors risk in the railway. Industry investigations into operational incidents frequently identify fatigue as either a causal factor or a contributing element. Research by the Rail Safety and Standards Board (RSSB) suggests that fatigue may play a role in around 20% of high-risk railway incidents.
This does not mean fatigue is the sole cause in most cases. More often, it appears alongside other factors such as workload, complex shift patterns, or environmental distractions. However, its presence can reduce a person’s ability to respond effectively when something unexpected occurs.
“Improving how fatigue is managed is fundamental to protecting people and supporting a safe and reliable railway,” says Richard Hines, ORR’s HM Chief Inspector of Railways.
“ORR has been clear, through its published guidance and industry engagement, that sustained leadership attention and effective risk management are essential if the industry is to reduce fatigue related harm and deliver lasting safety improvements.”
Part of the challenge lies in the nature of the railway itself. Unlike many industries, rail operations run almost continuously. Passenger services begin early in the morning and extend late into the night, while maintenance and engineering work often take place overnight when the network is quieter.
This operating model inevitably relies on shift work. Drivers, signallers, control room staff, and maintenance teams frequently work rotating shifts that may include early starts, night duties, and irregular schedules. While such patterns are necessary to keep the railway moving, they can disrupt normal sleep cycles and increase the risk of fatigue.
Scientific research has long shown that the human body is naturally programmed to sleep at night and remain active during daylight hours. Night shifts and early-morning duties can therefore conflict with the body’s circadian rhythm, making it harder for workers to obtain restorative sleep.
Over time, these disruptions can accumulate, leading to what is sometimes referred to as ‘sleep debt’. Even when workers feel they have adapted to shift patterns, their sleep quality may still be reduced compared with a conventional daytime schedule.
For many rail employees, the issue is compounded by long commutes, family responsibilities, or the need to adjust sleeping patterns between shifts. The result can be chronic fatigue that builds gradually over time.
A recurring theme
Accident investigations have played an important role in highlighting the risks associated with fatigue. The Rail Accident Investigation Branch (RAIB) routinely examines human-factor issues when analysing incidents, and fatigue is a recurring theme in many of its reports.
In a 2025 investigation into a buffer stop collision at London Bridge station, which occurred on 13 December 2024, fatigue was identified as a likely contributing factor. The train struck the buffer stops at low speed, causing damage but fortunately no injuries. Investigators concluded that the driver may have experienced a brief microsleep and therefore failed to brake in time.
The incident serves as a reminder that fatigue can affect even experienced professionals who operate within established safety systems. It also demonstrates the value of continuous monitoring and improvement in fatigue management practices.
Elsewhere, investigations into freight operations have prompted further scrutiny of fatigue risks. Following a collision between two freight trains at Loversall Carr Junction in 2022, industry groups examined how fatigue is assessed during shifts and whether existing procedures adequately capture real-time alertness levels.
Such investigations rarely point to a single cause. Instead, they highlight the complex relationship between scheduling practices, workload, environmental conditions, and individual wellbeing. The lessons learned from these events continue to shape industry guidance and operational policies.
Recognising the importance of fatigue management, the ORR has published detailed guidance outlining how rail organisations should address the issue. The regulator emphasises that fatigue should be managed in the same systematic way as any other safety risk.
This means organisations are expected to identify fatigue hazards, assess the risks they pose, and implement appropriate controls. Monitoring and review are also essential to ensure those controls remain effective over time.
Importantly, the ORR stresses that fatigue management is not solely about limiting working hours. While duty time limits remain an important safeguard, they do not always capture the full picture. Factors such as workload intensity, shift rotation patterns, rest opportunities, and commuting time can all influence fatigue levels.
As a result, many rail companies now adopt a broader Fatigue Risk Management System (FRMS) approach. This framework combines data analysis, staff engagement, and operational planning to identify fatigue risks before they lead to incidents.
Role of technology
Technology is increasingly being used to support fatigue management across the railway. For example, advanced scheduling software allows organisations to analyse shift patterns and predict where fatigue risk may be highest. These systems can take account of factors such as consecutive shifts, time of day, and rest periods between duties.
In some sectors of the transport industry, wearable devices and alertness monitoring systems are also being explored. These tools can detect physiological indicators of fatigue, such as changes in eye movement or reaction time. While such technology is still evolving, it may offer new ways to identify fatigue risks in real time.
Within rail, technological solutions are often combined with broader human-factors research. The RSSB continues to study how fatigue affects operational performance and how scheduling practices can be improved to support worker wellbeing.
One area of interest is the design of rosters that align more closely with natural sleep patterns. For example, gradual shift rotations are generally considered less disruptive than sudden changes between day and night duties. Similarly, ensuring adequate recovery time between shifts can significantly reduce fatigue accumulation.
While systems and technology play an important role, fatigue management also involves cultural change. Historically, fatigue has sometimes been viewed as an unavoidable aspect of shift work, with workers expected to push through tiredness in order to complete their duties.
However, modern safety thinking takes a different approach. Instead of placing responsibility solely on individuals, organisations are encouraged to create environments where workers feel comfortable reporting fatigue concerns without fear of stigma.
Open reporting is vital because fatigue can be difficult to detect from the outside. A driver or maintenance worker may appear alert while experiencing significant sleep deprivation. Encouraging honest conversations about fatigue helps organisations identify problems before they escalate.
Many companies now provide training on fatigue awareness, helping staff recognise the early signs of tiredness and understand how lifestyle factors can affect sleep quality. Education programmes often cover topics such as sleep hygiene, diet, and the importance of rest during shift work.
Supporting the workforce
Fatigue management is closely linked to broader wellbeing initiatives across the railway. Over the past decade, the industry has made increasing efforts to support both physical and mental health among its workforce.
Wellbeing programmes recognise that factors such as stress, workload, and work-life balance can all influence fatigue levels. Employees who feel supported and able to maintain healthy routines are generally better equipped to manage the demands of shift work.
Infrastructure improvements also play a role. Access to suitable rest facilities, quiet areas, and welfare amenities can make a significant difference during long or irregular shifts. These practical measures demonstrate that wellbeing is not just a policy concept but something embedded in day-to-day operations.
The emphasis on wellbeing aligns with the industry’s wider commitment to a ‘just culture’, where safety concerns can be raised openly and learning takes priority over blame. In such an environment, fatigue management becomes a shared responsibility between employers and employees.
Different perspectives
Although fatigue affects the entire railway, its impact can vary between different sectors. Freight operations, for example, often involve long-distance journeys that may take place overnight. In addition, drivers can spend extended periods working alone, which may increase the importance of monitoring alertness levels.
Passenger operations present their own challenges. High service frequencies, early-morning departures, and complex timetables can place pressure on staff schedules. At the same time, customer-facing roles such as onboard staff must maintain high levels of concentration while interacting with passengers.
Recognising these differences, industry groups have developed sector-specific guidance. The National Freight Safety Group, for instance, has worked with operators to develop tools that help assess fatigue during shifts. Such initiatives aim to ensure that fatigue management practices remain relevant to the operational realities of each sector.
Looking ahead
The British railway has long been regarded as one of the safest transport systems in the world. Achieving this level of safety has required continuous learning, investment, and collaboration across the industry.
Fatigue management represents the next stage in that journey. As the railway becomes increasingly sophisticated, attention is turning toward the human factors that influence operational performance. By understanding how fatigue affects workers and implementing effective controls, the industry can further strengthen its safety culture.
There is no single solution to fatigue. Instead, progress will depend on a combination of improved rostering practices, technological innovation, regulatory oversight, and ongoing engagement with the workforce. Each element plays a role in reducing risk and supporting the wellbeing of those who keep the railway running.
Ultimately, fatigue management is about recognising that people are at the heart of the railway. The network may be powered by advanced signalling systems, modern trains, and complex infrastructure, but its success depends on the individuals who operate and maintain it every day.
Ensuring those individuals are rested, alert, and supported is therefore not only a matter of wellbeing but also a fundamental aspect of safety.
As the industry continues to evolve, fatigue management will remain a key priority. By addressing this invisible risk with the same determination applied to traditional safety hazards, the railway can build on its strong record of safety and ensure that both passengers and staff benefit from a healthier, more resilient transport system.
