  1. MS Akbar says:

    my preference: BEML or Bombardier

  2. Delhi_Guy says:

    CRRC should be kicked out of bidding process itself.

  3. Clevin Gomes says:

    My preference was Hyundai Rotem and I was expected that the Hyundai Rotem will participate in the bidding. If Hyundai Rotem participated and won the Contract,
    then Mumbai will get its 1st South Korean Coaches. Fortunately both BEML and Bombardier are perfect as they have their factories in India.

  4. Aishwarya says:

    I was expecting Alstom to take part in these rolling stock bids. But, nevertheless Bombardier is one of the best rolling stock manufacturer in the business, plus it’s rolling stock business is almost acquired by Alstom.

  5. Roshan Menon says:

    Hope Crrc does not win the bid

  6. Hirak says:

    Cancel Chinese CRRC bidder. Dont allow Chinese company.

  7. Himanshu Doria says:

    BEML would work fine since they already had made prototype for Line 2&7. Bombardier would work too since they have design-manufacturing base here. CRRC is less than ideal since they have history of delaying deliveries. Noida metro is an example of this whose opening was delayed by almost 8-10 months because trains were not delivered at right time.

  8. Sreeraj R Warrier says:

    I wondered why Alstom not in the bidding process at first , but as Alston is already in the process of purchasing Bombardier they might have thought of staying out.. it’s better CRRC be kept out of bidding as CRRC even after winning so much of contracts in various metro projects in India has not fulfilled it’s promise to the Govt. Of India to open a manufacturing facility in India. So they should not be included.

    • Clevin Gomes says:

      Hyundai Rotem should participate in the bidding as, they will provide Make in India Initiative through BEML.

  9. Sanjay Kumar says:

    What’s the progress of the Mogarpada Depot ?

  11. USOZ says:

    No CRCC!

  12. Raghunandan Reddy C says:

    What happened to Alstom and others? Just three bidders?


    Hope , we make best from BEML , As in future can male more n more at home withnour own factories and technology.
    BEML. or else BOMBARDIER.

  14. MII says:

    What happened to BHEL ?

  15. AJAY Sakharam zore says:

    Being as rolling stock expert i prefer BT and BEML both are extremely competent and well known about Indian environment reequipments and services, I strongly preferer both companies for this supply.
