src-b3f70831c70dc965Independent think-tank analysis and the load-bearing source for the delay chain: the December 2019 coach contract as the cheapest bid, the local-content rule, the 2020 border clash and the new security-clearance requirement, the 2022 pivot to an Indian joint venture, visas cleared only in December 2023, structures complete by late 2023, opening 11 August 2025 with 3 of 15 trainsets. Carries the impact figure.
src-70e277425e6e4d49Supplier primary source: CBTC with automatic train protection and supervision. States it will be the first such project in India rated for unattended operation — a capability claim by the vendor, not evidence of how the line actually runs.
src-b7643355ea901d7dDecisive on the automation question: the trains are capable of unattended operation, but initially run in semi-automatic mode with a driver in the cab, to be upgraded after systems integration and regulatory approval. Direct fetch returned 403; outlet, article and these sentences confirmed through two independent search passes.
src-43e405e543c283fcTrade press for the launch facts: inaugurated 10 August 2025, 19.14 km, 16 stations, interchange with the Green Line, network to 76 km. Cites a project cost higher than the Takshashila figure.
src-344b0ebd5f1eacf6Most recent operational status: 13th six-coach set handed over 15 June 2026; 10 trains in service at a 7-minute peak headway; all 15 expected by August 2026.
src-a2fadffb7122292aCounterweight: a roughly 40-minute evening disruption acknowledged by the operator. Also confirms the headway sequence: three trains every 25 minutes at opening, a fourth cutting the wait to about 19 minutes.
src-fb67eea454bc5e0aRidership since opening: an average of about 60,000 a day, rising 5 to 6 per cent when a fourth trainset cut the headway. Outlet blocks automated fetching; headline and figures confirmed through search.
