Palakkad DRM inspects elephant intrusion detection system implementation
The EIDS is an initiative of Palakkad Division, Southern Railway, aimed at preventing elephant intrusions and enhancing the safety of both wildlife and train operations. It integrates an optical fibre–based sensing network with artificial intelligence–driven analytical modules to detect the presence and movement of elephants in real time. The system covers all identified elephant corridors along both the A and B lines of the section.
Installation of the system has been completed on both the A Line and the B Line. At present, signal validation, fine‑tuning, and systematic reduction of unconfirmed (spurious) alarms are in progress. Pre-commissioning activities are targeted for completion by July 30.
Using distributed acoustic sensing, sensors along the tracks capture vibration signatures (such as characteristic elephant footfall patterns) and relay data to the Distributed Acoustic Sensing unit located at Walayar. The AI engine and reference databases then localise any confirmed elephant presence to the exact kilometre.
Verified alerts will be relayed without delay to the Station Masters of stations concerned, Divisional Control Office, Palakkad Division, any level crossings between the stations, and locomotive pilots via dedicated display and alert interfaces, enabling timely operational responses to avert incidents. The estimated project cost is ₹15.42 crore, fully funded by the Railways.
During the visit, the DRM also inspected protection measures in the section, including solar fencing, rail fencing, clearance of vegetation on both sides of the track, and the functioning of railway‑constructed elephant underpasses.

Palakkad DRM inspects elephant intrusion detection system implementation
The Divisional Railway Manager (DRM), Palakkad Division, Arun Kumar Chaturvedi, inspected the ongoing implementation of the elephant intrusion detection system (EIDS) in the Kottekkad – Madukkarai section, a vulnerable stretch spanning Kerala and Tamil Nadu that has recorded wild elephant movements onto railway tracks.

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.

AI-based Intrusion Detection System to be installed to protect elephants from train accidents in Jharkhand
RANCH: Chakradharpur (CKP) Division under South Eastern Railway is all set to install an Artificial Intelligence (AI)-based Elephant Intrusion Detection System (EIDS) soon to prevent elephants from being mowed down by the speeding trains in Jharkhand. The Intrusion Detection System, for which a successful trail was completed recently along the Barabamboo-Chakradharpur-Lotapahar section, detects the presence of elephants close to the rail track and informs the loco pilots on time so that they can 'slow down' the speeding train. Two elephants, Jyoti and Sonu, were arranged from 'Vantara' for the testing to assess the impact of EIDS. The system will operate through fibre optics and sensors. This step will prove to be very crucial in the Kolhan region, where a large number of elephants cross railway tracks regularly and many of them are hit by trains and killed. The system has been developed by Indian Railways in association with the Forest Department. The railway officials have identified such spots where elephants move frequently and will install the system at such places. According to Railway officials, the system works within a radius of 30 meters on both sides of the railway track. When a herd of elephants comes within the radius, the system immediately sends an alert to the nearest station master. 'The station master will inform the train driver through the wireless system, after which the speed of the train is slowed down,' said Senior DCM Adiyta Kumar Chaudhary.
