MRI equipment to ensure safe, reliable train operations
Visakhapatnam: As part of its ongoing commitment to safety and efficiency in electric traction operations, Indian Railways adopted advanced Measuring, recording, and instrumentation (MRI) equipment. The state-of-the-art technology can be retrofitted onto tower cars to continuously monitor and record critical parameters of overhead equipment (OHE) such as contact wire stagger, contact wire height, and the precise positioning of traction distribution assets using GPS data. Waltair Division of East Coast Railway has also adopted this technology, ensuring safety and punctuality of the train operations. Divisional Railway Manager Lalit Bohra said that the pantograph maintenance posed challenges for electric trains. The pantograph, mounted on the rooftop of locomotives, is vital for maintaining uninterrupted contact with the overhead catenary that supplies power to the train. Traditional manual inspections, typically performed at depots, may not always detect emerging faults in time, potentially leading to overhead wiring failures, extended delays, costly repairs, and significant safety risks. To address these challenges, Indian Railways is leveraging MRI technology to enable real-time monitoring and proactive maintenance of pantographs and OHE, the DRM explained. Senior divisional electrical engineer (TRD) Shivanad Prasad opined that with the deployment of MRI scan equipment, it can swiftly analyse any changes in OHE parameters resulting from engineering works, modernisation efforts or routine maintenance. By minimising breakdowns and delays, MRI equipment plays a crucial role in ensuring trains run safely and punctually, allowing passengers to reach their destinations securely and in time, the officials underlined.

Waltair Division adopts MRI technology to ensure safety, punctuality of train operations
Indian Railways has introduced advanced Measuring, Recording, and Instrumentation (MRI) technology to enhance the safety and efficiency of electric traction. The system, mounted on Tower Cars, continuously monitors and records key Overhead Equipment (OHE) parameters such as contact wire height, stagger, and GPS-based asset positioning. Waltair Division of East Coast Railway has adopted this technology to ensure safe and punctual train operations. Divisional Railway Manager Lalit Bohra said pantograph maintenance is crucial, as the device connects the locomotive to the overhead power lines. Manual inspections often fail to detect emerging faults in time, leading to disruptions. The MRI system enables real-time monitoring and proactive maintenance, reducing the risk of pantograph entanglements and conductor failures. Senior Divisional Electrical Engineer (TRD) Shivanad Prasad said the equipment helps assess OHE changes due to maintenance or upgrades, while Senior Divisional Commercial Manager K. Saandeep added that the technology improves safety and punctuality by preventing breakdowns and delays.
