Mumbai Metro has deployed an AI-based wheel profile measurement system developed by IntelliRail on Metro lines 2A and 7 to detect wheel wear or damage. Installed at the Charkop depot, the system uses sensors, lasers, and cameras to capture precise measurements, reducing the need for manual inspections. It can alert maintenance teams automatically if wheels exceed preset limits, enabling proactive repairs. This step aligns with broader modernization efforts by MMMOCL and the shift toward condition-based maintenance, aiming to extend wheel life, reduce track stress, and improve metro safety.
Mumbai Metro has implemented an indigenous AI-powered wheel profile measurement system (AWPMS) designed to enhance operational safety and maintenance efficiency. Developed by IntelliRail, the system has been installed on Metro lines 2A and 7 and operates from the Charkop depot. It uses a combination of trackside sensors, lasers, and cameras to capture wheel measurements with high precision, allowing maintenance teams to monitor wheel health without extensive manual checks.

The system measures wheel profile with an accuracy of about 0.5?mm and wheel diameter within 1.0?mm. It identifies wear, deformation, or other irregularities that could compromise safety or performance. When a wheel crosses predefined limits, the system triggers automatic alerts through SMS or email to the maintenance staff, enabling timely repairs or replacement. This proactive approach reduces unexpected downtime, ensures smoother operations, and prolongs wheel life while minimizing track stress.
IntelliRail emphasized that this implementation is a major milestone under India's 'Make in India' initiative, marking the first deployment of such technology on Mumbai Metro. The project involved collaboration with BEML for technical support and guidance from DMRC. This step is part of a larger modernization drive by MMMOCL, aimed at shifting from periodic inspections to condition-based monitoring, a practice gaining importance across Indian metro networks.
