Mumbai’s suburban train network is being equipped with advanced CCTV cameras and voice recording systems to monitor operations and ensure swift investigation in the event of mishaps. This move by Indian Railways comes in response to rising concerns over commuter safety, especially following the recent Mumbra accident on June 9, in which five passengers lost their lives after falling off a local train.
The new Crew Voice and Video Recording System (CVVRS), currently being fitted into suburban train rakes, is designed to capture both real-time visuals and audio from the motorman’s cabin and trackside environment. According to officials from Central and Western Railways, the system has already been installed on 25 and 26 local train rakes, respectively, with further rollouts planned in the coming months.
Each local train has two motorcabs—at the front and rear—where a set of six CCTV cameras and audio recorders are being installed. Two cameras record the forward track view, two focus on the motorman or train manager’s cabin, and another two provide a 180-degree view of the track surroundings. The system’s AI-based features also monitor crew behaviour, helping detect signs of drowsiness, distraction, or even unauthorised mobile phone use.Officials said that had such surveillance been available earlier, incidents like the Mumbra tragedy could have been better understood. “Neither of the trains involved had on-board cameras, making it difficult to piece together the sequence of events,” said a senior railway official. “With CVVRS in place, not only can we determine what happened, but also prevent similar incidents in the future.”
In addition to visual surveillance, the audio recording feature captures crew communications, particularly during emergency situations. This can help determine whether standard safety protocols, including the use of colour-coded alerts, were followed correctly. The AI system can also issue automatic alerts to central control rooms when abnormal activity is detected, allowing real-time intervention.The cost of installing CVVRS in each motorcab is estimated at ₹1 lakh to ₹1.25 lakh. For locomotives used in long-distance trains, where the technology is being deployed as well, the cost is substantially higher at ₹8–10 lakh per engine. Western Railway alone has a fleet of 978 locomotives, indicating the scale of the planned safety modernisation.
Despite the technical advantages, the installation of surveillance equipment has faced resistance from railway unions. Representatives argue that constant monitoring may breach crew privacy and create an atmosphere of mistrust. Concerns have also been raised over the potential for disciplinary misuse of recorded footage.In response, the Railway Board has clarified that the CVVRS is intended solely for improving safety, efficiency, and post-incident analysis. Officials have assured that the data collected will be used for constructive feedback and counselling, not punitive action. The system places no operational burden on the train crew and is seen as a tool to support—not scrutinise—their work.
The initiative reflects a broader shift toward smart infrastructure in India’s public transport systems, where safety, accountability, and real-time data form the backbone of future-ready mobility. As Mumbai’s local trains carry over 7.5 million passengers daily, enhancing safety standards is not just a technical necessity but a public imperative.
While the debate around digital surveillance continues, the introduction of CVVRS marks a critical step in aligning railway operations with global best practices. If implemented with sensitivity and transparency, it could signal a new era of safer and more responsive urban transit in India’s busiest city.
