context_page_description: The Delhi Metro is a rapid transit system serving Delhi and its satellite cities of Ghaziabad, Faridabad, Gurgaon, Noida, Bahadurgarh and Ballabhgarh, in the National Capital Region of India.
  It is by far the largest and busiest metro in India, and second oldest after the Kolkata Metro. The network consists of Eleven colour-coded regular lines serving 285 stations with a total length of 389 kilometres.
  The system has a mix of underground, at-grade, and elevated stations using both broad-gauge and standard-gauge.
  Delhi Metro operates over 2,700 trips daily, starting at around 05:00 and ending at 23:30.
  Construction started in 1998, and the first elevated section on the Red Line opened on 25 December 2002. The first underground section on the Yellow Line opened on 20 December 2004.
  The development of the network was divided into phases. Phase I with 3 lines was completed by 2006, and Phase II in 2011. As of March 2020, Phase III is in the finishing stage and scheduled to be mostly complete by the end of the year. Construction on Phase IV was formally started on 30 December 2019. In 2010 Delhi Metro completed 10 years of operation, which was a major milestone to achieve.
context_section_description: As the network has expanded, high ridership in new trains has led to increasing instances of overcrowding and delays on the Delhi Metro. To alleviate the problem, 8 coach trains have been introduced in Yellow line and Blue line and an increase in the frequency of trains has been proposed. Infrequent, overcrowded and erratic feeder bus services connecting stations to nearby localities have also been reported as an area of concern. While the quality and the cleanliness of the Delhi Metro was lauded, the rising cost of fares have been routinely criticized, with fares being much more expensive compared to the bus services the metro replaced. One recent study has named the fares of the Delhi Metro as one of the world's most unaffordable. Another study finds that Delhi Metro may also have a low ridership problem compared to its size and may not be generating the amount of traffic a metro system generates.
