In recent years, Artificial Intelligence (AI) has emerged as a major force of change across industries such as the healthcare, retail, and automotive sectors and for the rail industry it offers significant potential for improving efficiency, safety, and passenger experience.
This blog explores how AI may transform the rail industry, the challenges it faces, and the key benefits it can offer.
Government Support and Rail Reforms
AI's potential to improve rail systems is becoming more widely recognised, particularly by policymakers. As part of the King's speech in 2024 the government announced its plans to create Great British Railways (GBR) and bring train operators under public ownership. Unifying track and train operations under public ownership may provide a platform for greater data sharing, technological integration and AI-driven budget prioritisation resulting in efficiencies across the industry.
Enhancing Safety with AI
Safety is a primary concern in rail operations and AI offers considerable potential to enhance these safety measures. Railway computers are increasingly being integrated into driver assistance systems, enabling autonomous detection of obstacles on the tracks. These AI systems can take necessary actions, such as issuing warnings or triggering emergency stops to prevent accidents.
AI can also plays a key role in inspecting rail infrastructure. By using AI algorithms combined with sensors and cameras, rail operators can monitor and identify damage to tracks or overhead lines in real time. Whether installed on regular trains or specialised diagnostic vehicles, these AI systems can conduct automated inspections far more efficiently than manual inspections.
Predictive Maintenance: Preventing Problems Before They Happen
One of AI's most promising applications in the rail industry is predictive maintenance allowing rail operators to foresee and address potential issues before they result in system failures or service interruptions. AI-powered predictive maintenance systems use sensors and data analytics to monitor the condition of trains, identifying early warning signs of component wear or damage. For instance, sensors can detect anomalies in brakes, bearings, and other critical components, allowing maintenance teams to take proactive action before any failures occur.
This approach offers several key advantages, including minimising downtime, extending the lifespan of equipment, prioritising maintenance spend and reducing the overall costs associated with reactive repairs.
Energy Consumption Optimisation
Energy efficiency is another area where AI has the potential to deliver significant benefits in rail transport. Machine learning (a subset of AI) can be used to optimise energy consumption, by allowing autonomous trains to dynamically adjust their speed and energy use based on real-time data. This helps to lower operational costs while minimising the environmental impact of rail operations. For instance, autonomous trains can be programmed to maintain optimal speeds during less busy hours or on downhill stretches, conserving energy without sacrificing punctuality or safety.
AI and machine learning can also be applied to predict and manage energy consumption on a larger scale, helping rail operators make data-driven decisions that reduce costs and carbon emissions. This is particularly important as the Government and train operating companies alike strive to meet sustainability targets.
Commercial and Legal Challenges of AI in Rail
We previously considered some of the top issues regarding AI implementation, and while AI presents numerous opportunities, its implementation also introduces a number of commercial and legal challenges. Within the rail sector, this includes issues regarding data quality, data ownership, intellectual property (IP) management, risk allocation and the negotiation of the underlying commercial contracts.
- Data Ownership and Usage
One of the most significant issues is determining who owns the data generated by AI systems and how it can be used. Clear agreements are needed to define who has access to the data, who can commercialise it, and how to ensure compliance with law, including the data protection regime. The risk of data breaches, including the loss of data and personal data, and what measures have been adopted to ensure the security and integrity of the AI systems will be an important part of the tendering process for both customers and suppliers of such systems.
- Data Quality
For AI systems to work effectively in the rail industry, they must rely on high-quality data. Poor data quality can lead to incorrect predictions, operational failures, and even safety risks. For instance, faulty data used in a predictive maintenance system could result in missed warning signs of an impending equipment failure, leading to service disruptions or accidents. Inaccurate data can also expose railway companies to legal liabilities if maintenance issues lead to accidents or customer dissatisfaction.
- Risk allocation
Risk allocation is another key consideration. Contracts between rail operators, AI technology providers and other stakeholders should specify the distribution of operational, legal, financial and compliance risks, including liability for data breaches, operational failures and system unavailability. As the regulation of AI continues to evolve, with the UK and EU taking potentially divergent paths, operators and providers will need to carefully consider the legal and regulatory regime within which they operate and the risks and remedies negotiated in commercial contracts will need careful consideration.
- Intellectual Property (IP)
Another important consideration is IP. AI technologies used in the rail sector, such as predictive maintenance systems and autonomous train controls, often involve substantial research and development. IP protections, including patents and copyrights, are essential to prevent unauthorised use of these innovations and to facilitate licensing agreements between railway companies and technology providers. Contracts should seek to clearly define ownership of IP related to AI applications and data inputs and outputs, specifying who holds the rights to any innovations or insights derived from the data. In a sector where multiple technologies and data sources converge, failure to address IP issues can lead to unnecessary disputes, financial losses and operational disruption.
- Workforce
With the automation of any manual processes, further consideration is needed to upskill and/or reallocate resource. So while the reduction of costs and improved efficiency are key benefits, rail operators will need to consider the human impact of implementing AI systems.
Conclusion
AI creates real opportunities to transform the rail industry (by enhancing railway systems, supporting sustainability objectives, improving safety procedures and passenger experience, as well as significant budget efficiencies), if industry participants and stakeholders can navigate the commercial and legal challenges outlined above.
