In recent years, the capabilities of Artificial Intelligence (AI) have advanced markedly, providing transformative potential across numerous industries, including railways. Today, railway companies worldwide have the opportunity to harness rapidly evolving AI technologies to optimise their planning and service delivery, leading to smarter, more efficient, and sustainable railways.
Adoption and use case of AI in Railways globally:
AI is playing a pivotal role in modernising railways around the world. Leading regions such as Europe and Asia have been at the forefront of this transformation, utilising AI to address critical aspects such as train punctuality, customer engagement, safety, and operational performance. The usage in various countries is as follows:
- UK: In the United Kingdom, Network Rail utilises AI to forecast and prevent equipment failures. By analysing data from sensors placed along the tracks, AI systems can identify signs of wear and tear or potential malfunctions before they lead to actual failures. This proactive maintenance strategy helps minimise downtime, enhance safety, and ensure that trains operate on schedule.
- Japan: The East Japan Railway Company employs AI to enhance the optimization of train schedules. AI algorithms analyse vast amounts of data, including historical train performance, passenger flow patterns, and current traffic conditions, to create more efficient and reliable train timetables. This optimization reduces delays and enhances the overall efficiency of train operations. By adjusting schedules in real-time based on AI insights, the company can better manage unexpected disruptions and improve the passenger experience through more predictable and timely service.
- USA: In the United States, Amtrak has introduced an AI virtual assistant called Julie to help passengers with travel information and ticket bookings. Julie can handle a wide range of inquiries, from providing train schedules and fare information to helping with booking and managing reservations. This AI-powered virtual assistant enhances customer engagement by offering quick, accurate, and 24/7 support, thus improving the overall customer experience.
- Austria: Austrian Federal Railways (ÖBB) combines internal data with Lidar scanning technology to monitor trackside areas and identify potential hazards such as trees that might fall onto the railway. By integrating these maps with existing data, AI systems can predict and mitigate risks, enhancing safety and preventing accidents. This proactive hazard detection allows ÖBB to take preemptive action, such as trimming trees or reinforcing vulnerable areas, thus ensuring smoother and safer railway operations.
- Germany: German Rail (DB) utilises AI to anticipate upcoming peaks in demand at stations and on long-distance services. By analysing patterns in passenger data, event schedules, weather forecasts, and other variables, AI can predict when and where demand will surge. This enables DB to dispatch high-capacity trains to relieve potential bottlenecks, improving passenger flow and reducing overcrowding.
Potential of AI in Indian rail sector:
As one of the largest rail networks globally, Indian Railways has started incorporating AI into its operations to improve efficiency, safety, and passenger experience. Some of the areas are:
- Predictive Maintenance: Indian Railways is utilising AI-driven predictive maintenance to oversee the condition of tracks and trains. AI algorithms evaluate data from sensors on locomotives and tracks to anticipate potential failures and schedule maintenance in advance. This approach reduces downtime, enhances safety, and lowers maintenance costs.
- Optimised Scheduling: AI is being used to optimise train schedules and improve punctuality in India. The Indian Railways uses AI-driven platforms to analyse passenger demand, weather conditions, and historical performance, ensuring efficient resource allocation and reduced operational costs. This optimization leads to improved punctuality and enhanced passenger satisfaction.
- Enhanced Passenger Experience: AI is enriching the passenger experience in India by delivering real-time information and personalised services. AI-powered chatbots offer passengers updates on train schedules, delays, and platform changes. Additionally, AI-driven recommendation systems offer personalised travel suggestions based on passenger preferences. The Indian Railways has implemented AI-driven chatbots to provide real-time travel information, improving passenger satisfaction.
- Safety and Security: AI is improving safety and security in Indian Railways by monitoring and analysing data from surveillance cameras, sensors, and other sources. AI algorithms can identify anomalies, such as unauthorised access to restricted areas or potential safety hazards, and notify authorities in real-time. The Indian Railways uses AI-driven surveillance systems to enhance security and safety across its network.
- Energy Efficiency: AI is optimising energy consumption in the Indian Railways by analysing data on train operations, weather conditions, and passenger load. AI algorithms optimize train speeds and schedules to reduce energy consumption, thereby lowering operational costs and minimizing environmental impact. The Indian Railways uses AI to optimise energy consumption, contributing to its sustainability goals.
Implementation in Indian Market:
In India, Indian Railways has embarked on a comprehensive modernization endeavour, which includes complete electrification, high-speed track construction, and the creation of tunnels, bridges, and other infrastructure. Protecting this extensive network from operational and security hazards is imperative, and achieving this through human effort alone is unfeasible. Advanced technologies and AI have thus become crucial catalysts for transformation. Some of the other areas are:
- Track Maintenance Blocks: In July 2018, AI was introduced to assess the condition of rail tracks, resulting in improved punctuality through AI-driven maintenance scheduling. The AI-developed repair and replacement calendar ensures timely track maintenance, leading to smoother operations.
- Live Tracking of Trains: Indian Railways has collaborated with the Indian Space Research Organisation (ISRO) for real-time train tracking, providing advantages to both the railways and passengers. Efforts are underway to install satellite navigation (Satnav) and communications (Satcom) based IoT devices on trains to enable autonomous geo-positioning. Advanced data visualisation tools will help identify the busiest routes and times.
- SMART Coaches: In August 2018, Indian Railways also introduced SMART coaches equipped with AI-based systems to monitor train health, predict maintenance needs, and enhance security standards, thereby improving passenger safety. These coaches feature Wi-Fi with real-time information, vibration-based sensors for detecting wheel and track defects, and AI-powered CCTV systems to enhance security and monitor railway staff behaviour, aiding in incident tracking.
Conclusion
The integration of AI in railways is revolutionising the industry by improving efficiency, safety, and customer satisfaction. AI technologies are empowering railway companies to tackle long-standing challenges and capitalise on new opportunities. As these technologies continue to evolve, the potential for further improvements in railway operations and passenger experiences will only grow, making AI an indispensable tool in the future of global rail transportation.
