After a prolonged delay, the inaugural train from China destined for Namma Metro's Yellow Line (RV Road-Bommsandra) finally arrived at Chennai port. The driverless train prototype, featuring communication-based train control (CBTC), is anticipated to reach the Hebbagodi depot near Electronics City by February 18. BMRCL's Chief Public Relations Officer, BL Yeshwanth Chavan, informed TOI, stating, Typically, customs clearance takes 3-4 days, following which the coaches will be transported to Bengaluru. At the depot, assembly will take place, followed by a series of tests before the train undergoes dynamic testing on the tracks. As this is a new train, we need to conduct 14 comprehensive tests for the main lines. Subsequently, signaling tests will be carried out. A total of 37 tests must be completed before seeking approval from the Commissioner of Metro Railway Safety. Compliance with rules mandates technical approvals from Research Designs and Standards Organisations (RDSO), Chief Commissioner of Railway Safety, and the Railway Board at different stages, Chavan explained. He emphasised that the entire testing process, involving technical experts from China Railway Rolling Stock Corporation (CRRC), will take a minimum of 4-5 months. Authorisation from CMRS will follow after the completion of these tests. Additionally, CRRC has delivered two train car body shells to its local manufacturing partner, Titagarh Rail System Limited, with the expectation of delivering these two trains in May.
