Much technological adoption in heavy industries today revolves around efficiency and cost improvements. As beneficial as such changes are, there’s another crucial factor to consider in railway operations — safety. Derailments, crashes and maintenance-related injuries can have devastating consequences, so rail companies must do all they can to prevent them.

While trains are relatively safe, especially compared to previous decades, there’s still significant room for improvement. Could emerging technologies be the solution?
The State of Railway Safety Today
Railway safety standards have generally improved over time with new technology and safer working practices. However, there has been a worrying trend in train operations in the past few years. While accidents are less common than they were decades ago, derailments have increased between 2020 and 2022, as have related fatalities.
Since that report came out, the unfortunate uptick in safety incidents has persisted. There were 6,513 railroad-related injuries in 2022 and 6,705 in 2023. Deaths followed a similar pattern — they increased from 908 in 2022 to 995 in 2023.
Some rise is to be expected from the lows in 2020, as the onset of the COVID-19 pandemic likely played a part. However, the continued increase since then is worrying, even if figures are still below historical highs.
How Can New Technologies Help?
Previous reports have noted that much of the recent uptick may stem from issues with aging rail infrastructure, maintenance and human error. Thankfully, new technologies can address all three of these challenges to make railroad operations safer.
Automation
Innovations like the Internet of Things (IoT) and artificial intelligence (AI) enable substantial safety improvements through automation. These technologies can reduce human error, as well as detect and respond to potential hazards before workers notice them.
One recent study developed an AI model that can identify track conditions with 97% accuracy by monitoring real-time IoT data. As a result, it can spot abnormalities as soon as they arise. Immediately alerting crews of any issues gives them time to respond and stop or redirect the train to prevent an accident.
Automated control systems have similar benefits. AI can respond faster to incoming hazards than what’s humanly possible, and it’s impossible for machines to get tired or distracted. Consequently, a robot conductor is less likely to make dangerous mistakes.
Proactive Maintenance
AI and IoT also enable more timely repair practices to keep train cars and tracks in optimal condition. Predictive maintenance (PdM) can detect issues before they cause failures and alert technicians of the problems before they’re outwardly noticeable.
In addition to preventing crashes, PdM’s efficiency ensures equipment lasts longer. Longer life spans mean less downtime and costs, giving rail operators more time and money to invest in other safety improvements.
Some rail systems have already begun implementing PdM, and the results have been impressive. One system in Australia can predict rail distortions up to three days ahead of time by analyzing temperature shifts and related conditions. This insight lets crews fix rails before warping could endanger a train.
Infrastructure Upgrades
Long-term rail maintenance and upgrades can see similar benefits from technology. The freight rail industry currently faces a $45.2 billion repair backlog, making planning difficult.
Deciding which investments will yield the most needed improvements is crucial to make the most of the situation. However, doing so manually is challenging. AI and data analytics help by providing more information and making that insight more interpretable.
IoT data can provide up-to-date insight into different rail sections’ state of repair. Machine learning can then analyze this information to tell operators which upgrades are most needed, helping them allocate resources efficiently. By finding and fixing the biggest problems first, organizations can prevent the largest number of infrastructure-related accidents.
Employee Health and Wellness
The impact of emerging technologies on worker health and well-being is also worth noting. While train crashes may be the most obvious source of injuries in this industry, less dramatic causes deserve attention, too.
Maintaining railroads is physically demanding work, which can lead to repetitive strain injuries or overexertion. Robotic exoskeletons can reduce these hazards by taking much of the load off workers’ joints and muscles as they lift, squat and hold things overhead. One study found that exoskeletons can reduce muscle activation by up to 39% in some tasks, significantly lowering the risk of musculoskeletal injuries.
Automated train operational technologies can also help. Conductors and other onboard staff with lower workloads, thanks to automation, can go through the workday with less exhaustion or distractions. As a result, their focus and mental well-being improve, making them more likely to respond quickly and appropriately to any unexpected hazards, preventing accidents.
Technology Provides a Safer Way Forward
In light of all these use cases, the potential for emerging technologies in railway safety is too big to ignore. While tech is unlikely to eliminate accidents altogether, it could offer the efficiency, insight and workload reduction railroad operations need to reverse the current trend. Even one injury or fatality is too many, so rail freight businesses cannot overlook this opportunity.
