en.Wedoany.com Reported - Delhi Metro Rail Corporation (DMRC) has initiated the mid-life refurbishment project for its RS-1 type trains on the Blue Line, involving a total of 70 trainsets operating on the Red and Blue Lines. According to an official DMRC announcement, these trains were commissioned between 2002 and 2007, having served for 19 to 24 years. The refurbishment aims to enhance reliability, passenger comfort, and the overall commuting experience. The project is progressing in three phases. The first and second phases have already completed the upgrade of 30 trainsets. The third phase will refurbish 22 Blue Line trains, with the target of completing all work by November 2027.
The refurbishment encompasses a comprehensive upgrade of passenger cabin interiors, electrical systems, and safety features. Passenger coaches and driver cabins have been repainted. Electrical panels and miniature circuit breakers have been replaced with high-reliability units. A network protocol architecture-based Passenger Announcement and Information System, integrated with LCD-based dynamic route maps, displays real-time route information, current time, and next station announcements. It also facilitates two-way communication between passengers and the train operator in emergencies. The upgraded Closed-Circuit Television (CCTV) system provides full-coverage surveillance, enhancing passenger security.
Safety systems have been concurrently reinforced. All coaches are equipped with a new fire detection system featuring smoke and temperature sensors. Outdated relays have been replaced with advanced control units. Each coach has been fitted with additional charging points for mobile phones and laptops, catering to modern commuting needs. Newly installed jumper cables and connectors support the operation of the existing announcement/information and fire detection systems while providing interfaces for future technological upgrades.
Dr. Vikas Kumar, Managing Director of Delhi Metro, recently inspected the first train refurbished under the third phase, which has already entered passenger service. As of the inspection date, a cumulative total of 31 trainsets have been upgraded. The first and second phases saw the refurbishment of 12 and 18 trainsets respectively. For the third phase, work on another 9 trains is about to commence, with the remaining 9 trains to follow sequentially.
DMRC stated that the mid-life refurbishment extends the operational lifespan of existing rolling stock through technological upgrades, modernizing the fleet in a cost-effective manner. Post-upgrade, the trains achieve parity with newer trainsets in terms of real-time information display, cabin amenities, and safety features. The Delhi Metro Blue Line, a major corridor connecting Dwarka to Noida and Vaishali, handles one of the highest daily passenger volumes in the network. This refurbishment project plays a crucial supporting role in ensuring the stability of commuter services in the National Capital Region.
