Bengaluru: The safety inspection of the Yellow Line by the Commissioner of Metro Railway Safety (CMRS) will begin Tuesday, and is expected to continue for four days. CMRS inspection is a statutory requirement, and the line can be opened to the public only after receiving the necessary approval.Bengalureans have long been awaiting the opening of the 18.8km line from RV Road to Bommasandra, which connects Electronics City — one of the city’s major IT corridors. Due to the non-availability of the required number of coaches, BMRCL postponed the launch several times. Recently, BMRCL management set Aug 15 as the new deadline to open the line.A senior BMRCL official said CMRS of the southern region, AM Chowdhary, and his team will inspect the line starting Tuesday. “As this is a new line, the inspection may go on for four days. CMRS inspection is a crucial step towards opening the line. We’ll announce the opening date based on the outcome of the safety inspection.”So far, BMRCL received only three sets of trains. The fourth set is expected to arrive in Aug. Earlier, BMRCL considered opening the line with five-seven stations, but further clarity will come only after the CMRS inspection.
