Delhi happenings: Delhi Metro - current and future

Delhi Metro is currently running through some of the major populations centers of Delhi, running through major parts of West Delhi, North Delhi, and East Delhi. It has taken load off the roads (although how long that lasts is a matter of debate given the number of vehicles getting added to Delhi roads per Delhi). Delhi Metro was started on December 24, 2002, after a long period of planning, and was greeted as a major improvement to the traffic infrastructure of the city. It has helped, and has attracted a large number of commuters on a regular basis (try taking the Metro route from Connaught Place to Dwarka at 6 in the afternoon).
Originally the route of the metro line was on these 3 lines: Line I (Shahdara - Rithala), Line II ( Vishwa Vidyalaya - Central Sectt.), and Line III (Indraprastha- Barakhamba Road - Dwarka) (the Indrapastha and Barakhamba Road stations were added later). The stations that are on this route are:
