Delhi's new metro system has much potential for efficient and comfortable travel, and though in most parts of Delhi this potential has already been met, India's metro system has much more to grow. Currently there are three available transportation lines which cover some of northern  Delhi. Line 1 covers the distance between Shahdara and Rithala (22km); line 2 covers the distance between Vishwa Vidyalya and Central Secretariat (11 km); and line three covers the distance between Indraprastha-Barakhamba Road and Dwarka (32.1 kms). Metro trains are available at a  frequency of 4 minutes during peak time. For further details regarding train timings, stops, etc. visit
