All 7 bids have now been sent for technical bid evaluation which can take a couple months to complete. When that is done, the financial bids of the technically qualified bidders will be opened to reveal who’s the lowest bidder and most likely supplier.

This telecom package is among the last few pending packages for Line-4 where all 5 civil packages are under construction with financial bids having been opened for major system contracts such as rolling stock and electrification. In fact I hear financial bids of 5 bidders for its E&M contract have also been opened. If someone has bid values, then leave a comment below or message me here.

    Hi TMRG

    I would like to give a suggestion that you add information about train frequency in peak and off peak hours for every metro in their respective info page. You can also add the opening and closing timings for them.

    The frequency is the most important factor that determines whether the system is actually good and usable or not.

    I was in Ahmedabad today and thought to check out the new metro. I was SHOCKED to know that the trains are running every 25 minutes!
    That is ridiculous. How do you expect people to use the system and for it to be successful in any way?
    Then I was SHOCKED AGAIN that the operational timings for the system are 9:00 AM to 8:00PM only 11 hours a day. It should atleast be 7am-10pm if not more.

    I don’t know why this is the case but whatever it is I don’t see good readership for the system if this is how they plan to operate it.

    I looked for other systems and other than delhi no one had proper information regarding train frequencies. I would say even for delhi green line train off peak hour frequency of 12 min is atrocious when compared to less than 3 min on some lines.

      Good idea. I’m not quite sure what GMRC is up to. 25 minutes is atrocious, why even operate then?! Other smaller systems have a better grip on things.
