The Indian Railways has announced plans to begin a nationwide pilot of an AI-driven predictive maintenance systemdesigned to detect faults in tracks, wheels, and signaling equipment before breakdowns occur. The initiative — part of the Railways’ broader “Mission Raftaar and Safety 2030” program — aims to use sensors, data analytics, and machine learning to reduce derailments, improve punctuality, and modernize India’s transport backbone.
New Delhi, October 22 —
After years of reactive maintenance and human inspection, the Indian Railways is turning to Artificial Intelligence to predict — and prevent — potential failures across its 68,000-kilometer network.
Under a pilot beginning in December 2025, the Ministry of Railways will deploy AI-enabled predictive maintenance systems on select routes of the Northern, South Central, and Western Railway zones. The project, developed jointly with IIT Madras, TCS, and BEL, represents one of the largest AI infrastructure rollouts in the country’s public sector.
“Our goal is zero-accident, zero-delay operations. Predictive AI will be our digital sentry,”
said Railway Minister Ashwini Vaishnaw at a press briefing in Delhi.
How Predictive Maintenance Works
Unlike traditional “time-based” maintenance — where components are replaced after fixed intervals — predictive maintenance relies on real-time data and AI analytics to determine when parts actually need servicing.
Thousands of IoT sensors attached to rail tracks, wheels, and engines continuously monitor parameters like vibration, temperature, sound frequency, and axle pressure.
These readings are sent to central servers, where AI algorithms trained on historical data flag anomalies that could signal early-stage wear, misalignment, or overheating.
“It’s like giving trains a sixth sense,” explained Dr. Karthik Narayanan, lead researcher at IIT Madras’ RailTech Lab.
“The system detects trouble before humans can see or hear it.”
The Problem It Seeks to Solve
In the last decade, India has averaged over 100 rail accidents annually, most caused by equipment fatigue, human error, or delayed maintenance.
Even minor breakdowns often cascade into widespread delays, disrupting passenger schedules and freight logistics.
Predictive analytics can transform this landscape by:
- Detecting faults early, reducing downtime.
- Extending asset life.
- Minimising derailments and collisions.
- Improving operational efficiency and punctuality.
“Each avoided derailment saves not just crores in assets but hundreds of lives,” said Sanjeev Mittal, Member (Infrastructure), Railway Board.
The Pilot Project: Where and How
The pilot will cover Delhi–Mumbai, Delhi–Howrah, and Secunderabad–Vijayawada corridors — representing varied terrain and traffic density.
The plan includes:
- Smart Axle Sensors to detect vibration changes.
- Track Ultrasonic Scanners for micro-crack detection.
- AI Cameras at junctions analysing wheel alignment.
- Central Data Command Centres at Secunderabad and Prayagraj.
These command hubs will analyse millions of data points daily, using machine learning models that become smarter with each trip.
The Technology Backbone
The system’s intelligence relies on three core components:
- Edge Devices: Real-time data acquisition modules mounted on locomotives.
- AI Models: Developed using open-source frameworks like TensorFlow and PyTorch for anomaly detection.
- Cloud Integration: Real-time dashboards for engineers via RailCloud, the Indian Railways’ internal cloud platform.
Predictive maintenance will run alongside the Automatic Train Protection (ATP) and KAVACH safety systems, creating a fully integrated digital ecosystem.
Collaboration and Partnerships
The Railway Ministry has roped in:
- IIT Madras – algorithm development and pilot analytics.
- Bharat Electronics Limited (BEL) – hardware sensors and networking.
- TCS – software integration and cybersecurity.
- ISRO – satellite communication for remote route connectivity.
“The collaboration is a perfect example of Atmanirbhar innovation,” said BEL Chairman Anandi Ramakrishnan. “It’s Make-in-India technology for global-scale rail safety.”
International Inspiration
India’s move mirrors successful systems in Japan’s Shinkansen, Germany’s Deutsche Bahn, and France’s SNCF, where predictive AI has slashed maintenance costs by 20% and improved punctuality to 99%.
Railways officials believe the Indian model could eventually rival these global benchmarks once scaled.
Economic Rationale
According to internal Railway Board projections:
- Predictive maintenance could cut unplanned maintenance costs by 25%.
- Improve average asset uptime by 18%.
- Save nearly ₹4,000 crore annually in repairs and delay penalties.
With 22 million passengers daily, even a one-percent improvement in punctuality translates to millions of hours savednationwide.
Labour and Training
One of the challenges will be upskilling 1.2 lakh technical staff to operate AI-assisted diagnostics.
Workshops are being set up in Lucknow, Chennai, and Nagpur for AI literacy programs covering data logging, model interpretation, and safety auditing.
“This is augmentation, not automation,” clarified Railway Board Chairman A.K. Lahoti. “AI helps engineers, it doesn’t replace them.”
Data and Privacy Safeguards
The system will process sensor and geolocation data but exclude passenger or personal information.
All analytics will comply with the Digital Personal Data Protection Act (2023), and a Rail Data Governance Councilwill monitor usage.
Independent audits by NIC and CAG will review cybersecurity and AI ethics compliance annually.
Early Results from Lab Trials
At IIT Madras’ test tracks, prototype sensors identified 97% of artificially induced faults.
In one case, the algorithm predicted a bearing failure 72 hours before it occurred — enough time for preemptive replacement.
“This is the future of maintenance — from hindsight to foresight,” said Professor R. Subramaniam, chief project scientist.
Challenges on the Tracks
- Network Complexity: India’s rail system operates under diverse climates — deserts, coasts, mountains. Models must adapt locally.
- Legacy Infrastructure: Integrating old rolling stock with smart sensors poses compatibility issues.
- Connectivity Gaps: Some sections still lack high-speed data links, limiting real-time transmission.
The Ministry plans to install 5G-enabled communication towers along key routes by 2026 to ensure uninterrupted data flow.
Environmental Impact
Predictive maintenance reduces material waste and energy use by replacing components only when necessary.
It aligns with Indian Railways’ Net Zero 2030 pledge and will be powered partially by solar-run monitoring stationsalong routes.
The initiative also aims to lower carbon footprint by cutting unnecessary locomotive idling.
Global Export Potential
Once proven, India may export the model to other developing countries under the South Asia Rail Cooperation Framework (SARCF), supported by the World Bank.
Experts from Kenya, Indonesia, and Vietnam have already expressed interest in joint pilots.
“If successful, India could become the world’s AI rail safety hub,” said World Bank transport advisor Maria de la Cruz.
Funding and Timeline
The ₹1,200-crore pilot is financed jointly by the Railway Technology Mission Fund and the Ministry of Electronics & IT’s AI Mission.
A national rollout is expected by 2028, covering all high-density corridors.
Budget allocations for FY2026–27 will include dedicated outlays for hardware procurement and AI training facilities.
Voices from the Field
At Delhi’s Paharganj yard, locomotive engineer Manish Saini inspected a test sensor on a wheel axle.
“When this small box tells me something’s wrong before it breaks, it’s like having a guardian angel,” he said with a grin.
Rail unions, traditionally wary of automation, have cautiously welcomed the pilot after assurances that jobs won’t be cut.
The Big Picture: Digital Railways Vision
Predictive maintenance is one piece of the Railways’ broader modernization puzzle, which includes:
- 100% electrification,
- AI-driven crew scheduling,
- Smart ticketing through Face ID, and
- Drone-based line inspections.
By 2030, the Ministry envisions a fully data-driven rail network, combining efficiency with passenger safety.
Conclusion: The Age of Intelligent Tracks
The Indian Railways’ AI predictive maintenance project represents a quiet revolution — a shift from repairing breakdowns to anticipating them.
If implemented successfully, it could redefine how India manages its most complex and critical public asset, turning every train, track, and wheel into a sensor of safety.
In the words of Minister Vaishnaw:
“We are no longer maintaining trains; we are maintaining trust. AI will help us deliver punctuality, precision, and protection — all at once.”
