Railway Board grants conditional clearance to RCF-Built Vande Bharat Trainset with Alstom Propulsion

New Delhi, India (Rail & Metro Today): The Railway Board has granted conditional clearance for the introduction of a 16-car Vande Bharat Chair Car trainset manufactured by Rail Coach Factory (RCF), Kapurthala, featuring propulsion equipment supplied by Alstom. The trainset has been cleared for operation at speeds of up to 160 km/h, subject to compliance with specified technical and operational conditions. The development marks an important step in expanding India's Vande Bharat manufacturing ecosystem, with RCF taking on the production of an integrated trainset using Alstom's propulsion package. It is important to clarify that the trainset has been manufactured by RCF and is not a complete train manufactured by Alstom. According to reports, the Railway Board issued its clearance letter on October 23, 2026, following certification by the Research Designs and Standards Organisation (RDSO) and a high-speed trial conducted under the supervision of the Commissioner of Railway Safety (CCRS) on October 8. During the trial, the trainset reportedly achieved a speed of 180 km/h. The clearance represents a significant technical milestone for the RCF-built Vande Bharat trainset. However, the Board's approval is conditional and requires attention to several technical observations before the trainset can progress towards regular passenger operations. Issues reportedly identified in the Railway Board's communication include touchscreen responsiveness of the Driver Display Unit (DDU), electrical protection arrangements, fault-tracing provisions and equipment labelling. Other observations concern the secure installation of fire extinguishers and equipment cubicles, fire-survival cabling and crash-hardened recording systems. The Board has also sought a review of the 270-kW traction motor (TM) rating. The motor rating needs to be assessed in relation to the train's overall performance requirements, thermal duty cycle, energy consumption and compatibility with other propulsion system components. A higher motor rating does not automatically translate into better performance; its suitability depends on the complete system design. The development is significant for both RCF and Alstom. For RCF, the project represents progress beyond conventional passenger coach manufacturing towards the production of integrated, modern trainsets. For Alstom, the clearance provides an important qualification reference for its propulsion package within the Vande Bharat programme. The development also broadens the range of manufacturing and propulsion options available to Indian Railways, potentially supporting greater competition, production flexibility and supply-chain resilience. However, the use of domestic manufacturing facilities should not automatically be interpreted as complete localisation of propulsion technology. The extent of technology transfer, component localisation, software access and long-term maintenance capabilities will remain important considerations. The trainset's reported achievement of 180 km/h during trials should be distinguished from its approved operating speed. The Railway Board's conditional clearance is for operation at up to 160 km/h, subject to applicable technical requirements and operational approvals. Actual passenger-service speeds will also depend on route characteristics, track and signalling infrastructure, safety standards and the introduction sanction of the operating railway. A successful high-speed trial does not, by itself, authorise commercial operations at the same speed. Similarly, technical clearance, deployment on a route and reliable passenger service are separate milestones. Completion of the outstanding observations and compliance with the prescribed conditions will be essential before the trainset enters regular service. Beyond obtaining initial approval, the next challenge will be ensuring consistent quality, maintainability and operational availability throughout the trainset's service life. This will require d…
