The exact number of coaches to be procured has not been specified in the basic 1-pager online or newspaper (below) notices, but CMRL in the past has revealed they are looking procure 288 coaches and wet-lease 126 coaches to run services on the project’s 3 corridors.

Unlike Phase 1 where CMRL procured 4-coach Alstom Metropolis trains, CMRL plans to procure and run 3-coach trains expandable to 6-coaches in the future. All trains will most likely be capable of being operated “driverless” on the unattended train operations (UTO) mode.

Package: Phase – II / ARE03

Brief Scope: Design, manufacture, supply, testing, commissioning of standard gauge metro rolling stock (electrical multiple units) and training of personnel for Chennai Metro Project Phase II

The financier of the rolling stock and other systems’ procurement is unknown, but it could possibly be either Japan International Cooperation Agency (JICA) or the Asian Development Bank (ADB) which, besides a part of Line-3, is also evaluating a proposal to finance Line-4’s 10 km underground section through a combined $780 million (approx. Rs. 5890 crore) loan.

I’ll update the post if the bid documents, which go live on December 26, contain any further information on specifications, dimensions and funding.

December 23 Update: Bid documents are now live. This tender is only for the 26.1 km Line-4’s coaches. CMRL is looking to procure 78 cars (26 trainsets of 3-car configuration) and will run them in a DMC+TC+DMC configuration with 67% propulsion. Also confirms train-sets must support Grade of Automation level-4 for “driverless” Unattended Train Operations (UTO)

    Why Chennai metro is opting for three car coaches instead of four car coaches for phase 2 operation ???

    • TMRG says:

      Perhaps by looking at ridership figures of Phase 1 lines? With advanced signaling 3-coach trains these days can provide a similar or higher throughput by safely allowing high frequencies.

  6. Ravi says:

    Hi TMRG,
    When the Power Supply & Track work packages are expected for Chennai Metro Phase-2?

  7. AC says:

    What is the main difference between 78 cars and 210 cars, why they are invited seperately?
