Delhi Metro stopped 3 times in a week – Kites and mountains of rubbish are the reasons

Delhi: The mountain of garbage in Ghazipur has become a big problem for the Delhi Metro Rail Corporation (DMRC). Delhi Metro’s blue line is often affected by kites flying around the Ghazipur landfill.

Delhi metro services were affected last Monday after a black kite collided with a high voltage wire between Yamuna Bank and Indraprastha metro stations causing much inconvenience to commuters.

Two days later, an eagle dropped a piece of cable on the wire, affecting subway service.

According to a report by Live Hindustan, the sister publication of Livemint, birds have become a big problem for the Delhi Metro. In 2017, the Delhi Metro tried to combat this problem by installing spiked discs. An official told the daily that the German technique had successfully solved the problem, but the increase in the number of kites is a cause of concern for the DMRC, especially at Yamuna Bank and Indraprastha stations.

Delhi metro officials told Live Hindustan that the eagles that soar around the Ghazipur landfill cross the Yamuna in search of water, therefore they often come into contact with the high voltage wires of the metro.

There is currently no technology in the world to prevent birds from hitting power lines, the official said. However, DMRC is in the process of evaluating the sudden wire breakage.

Delhi Metro: Reason for Affected Services

1. Birds: Many times the catenary wire breaks due to the collision of the bird, which affects the services

2. Signaling issues: A signaling fault in a particular section of the metro line results in a loss of communication with the control room, forcing the train to operate manually.

3. Loss of identification: metro trains have an identification number at the time of operation. The loss of identification of a train stops its display in the control room.

4. Other reasons: If metal, clothing, etc. fall on the cables of a subway corridor (raised part), it causes brakes in speed.

Delhi Metro: How to Solve the Bird Problem

1. Delhi Metro installed the Spikes Disc in 2017. It is mounted on the insulating cap of the pole so that the bird cannot nest there. Over 2000 spiked discs have been installed on Delhi Metro Phases I and II.

2. A dangler is technically a circular shape with colored paper on it. It was installed on poles at various locations in subway stations and elevated areas. Experts say that the pendants reflect the bird and therefore they fly away.

3. Bird nets: To stop birds, Delhi Metro has also used nets at Indraprastha and Yamuna Bank stations. These traps have also been installed at stations like Karol Bagh and RK Ashram.
