For an easy interchange between green and pink lines, the Delhi Metro Rail Corporation (DMRC) is constructing a walkway of 230 metres connecting the two lines. Trains running on Delhi Metro’s Green Line will stop between Punjabi Bagh and Shivaji Park stations. Passengers will get down and walk to the Punjabi Bagh West station of the Pink Line. The green line and pink line are almost perpendicular at their point of mutual passage. "To facilitate efficient interchange, additional platforms will be constructed in green line where passengers will be allowed to board and deboard. The passengers will then go down from the platforms and take the walkway to finally reach the concourse area of Punjabi Bagh West," DMRC tweeted. This will be the first interchange facility of its sort in the Delhi Metro network where passengers will change trains.
Delhi Metro's Pink Line is 58.9 km long and covers Delhi in 'U' shape. It consists of 38 metro stations from Majlis Park to Shiv Vihar. The Pink Line has the highest point of Delhi Metro at Dhaula Kuan, and country's smallest metro station at Ashram.
Delhi Metro's Green Line is the broad gauge which connects a total of 21 metro stations starting from Inderlok and ends at Birg Hoshiar Singh.
In August, the Noida Metro Rail Corporation (NMRC) opened a 300 metre-long walkway connecting Delhi Metro's Blue Line with Aqua Line of Noida Metro. The walkway links Sector 52 station of Blue Line with Sector 51 of Aqua Line. The route has 21 stations and all of them are equipped with platform screen doors to prevent commuters from falling onto the tracks. The walkway, built by NMRC, was inaugurated by Durga Shankar Mishra, Secretary, Ministry of Housing and Urban Affairs (MoHUA).
