Surpassing, London's 140 year-old underground rail network popularly known as 'Tube' will be a major achievement for Delhi metro which made its advent nearly 12 years ago.
According to reports, DMRC will commence the work for phase IV project in next few months. With this, the total length of Delhi Metro network would go up to 434 km exceeding 140-year-old London's Tube which has length of 402-km by 2021.
By achieving this, the Delhi Metro will become the third largest metro network in the world after Shanghai (538 km) and Beijing (465 km). Currently, the Metro is the tenth-largest-network ranking globally and is set to move up three notches to seventh place by the end of Phase 3. By 2021, it is expected to become the second-largest network in the world.
