Trains on Delhi Metro's Airport Express Line are running at a reduced speed of 25 kmph between Dhaula Kuan and Shivaji Stadium stations due to damaged signalling cables. An attempted theft in the early hours of Sunday resulted in approximately 800 meters of cables being cut, disrupting the signalling system. While the thieves could not take the cut pieces, repairs are being conducted overnight to minimize passenger inconvenience. Services on other parts of the line remain normal.
