The Hazrat Nizamuddin-Shiv Vihar standard gauge corridor of the Delhi Metro, which is part of Phase III, will have a record number of sharp curves.
"There are uneven twists and turns in this 25-km elevated corridor. So we have been forced to construct 14 curves on this stretch, which passes through highly congested areas of east Delhi such as Trilokpuri, Anand Vihar, Karkardooma, Welcome and Seelampur," said a Delhi Metro spokesperson.
Curves with a radius between 200 and 300 meters are considered 'sharp' in urban rail construction. "The work on building sharp curves requires a great deal of engineering skills and several factors have to be kept in mind while designing special segments/spans at the turn concerned," the spokesperson added.
The Hazrat Nizamuddin-Shiv Vihar corridor is a part of the 59-km-long Mukundpur-Shiv Vihar corridor.
