New Delhi: Prime Minister Narendra Modi said on Monday that metro train services will be extended to 25 cities with an over 1,700-km network by 2025 in the country as he flagged off India’s first-ever driverless train operations on Delhi Metro’s Magenta Line. Modi noted that metro service was confined to only five cities in 2014, when his government came to power at the Centre, and said it has continuously been expanded to different cities, a testimony of people’s “ease of living” being ensured by his dispensation. He said that the central government did not see urbanisation as a challenge but used this as an opportunity and took a swipe at earlier regimes, saying they did not address the infrastructure demands of growing cities for decades.
