Delhi Metro Blue Line
Dwarka Sector 21 to Noida Electronic City, with a branch from Yamuna Bank to Vaishali: 57 stations across Delhi and Uttar Pradesh.
About the Blue Line
The Blue Line has a main route from Dwarka Sector 21 to Noida Electronic City and a branch from Yamuna Bank to Vaishali (DMRC lines 3 and 4). Trains from Dwarka run through to either branch; between the two branches you change at Yamuna Bank.
On 20 October 2026 DMRC’s website showed the line as “Normal Service”. That is the only live information DMRC publishes; check it on the day you travel.
DMRC runs the Blue Line as two lines, 3 and 4, and gives 63.79 km for the two together. Line 3 is the main route of 50 stations between Dwarka Sector 21 and Noida Electronic City; Line 4 is the eight-station branch from Yamuna Bank to Vaishali. Twelve main-route stations, from Noida Sector 15 on, are in Gautam Buddha Nagar district; the branch ends in Ghaziabad.
Most of the line is elevated. Five stations are underground: Dwarka Sector 21, Rajouri Garden, Rajiv Chowk, Barakhamba Road and Mandi House; Kirti Nagar and Yamuna Bank are at grade. Eleven stations are interchanges, among them Rajiv Chowk for the Yellow Line, Dwarka Sector 21 for the Airport Express, Dwarka-Kakrola for the Grey Line, Janakpuri West and Botanical Garden for the Magenta Line, and four shared with the Pink Line: Rajouri Garden, Mayur Vihar-I, Karkarduma and Anand Vihar ISBT.

Departure times from this station on a weekday, as DMRC’s journey planner gives them (checked on Tuesday 20 October 2026; the planner takes no date). DMRC does not publish separate Saturday, Sunday or holiday times for each station, and on special days it announces changes in advance. A last train after midnight belongs to the previous evening’s service. “Not published” means DMRC’s own answer was inconsistent (arrival before departure), so we leave it out.

History
The first Blue Line section, from Dwarka-Kakrola (then called Dwarka) to Barakhamba Road, was opened by Prime Minister Manmohan Singh at the end of December 2005. The line reached Dwarka Sector 9 on 1 April 2006 and, at the other end, was extended from Barakhamba Road to Indraprastha on 11 November 2006, through Mandi House and Supreme Court. Yamuna Bank followed on 10 May 2009, and the section from Yamuna Bank to Noida City Centre on 12 November 2009. The last stretch in Dwarka, Sector 9 to Sector 21, opened on 30 October 2010.
The branch began in January 2010 as a 6.25 km line from Yamuna Bank to Anand Vihar ISBT, with Laxmi Nagar, Nirman Vihar, Preet Vihar and Karkarduma, where the platforms are 20 metres above the ground. It reached Kaushambi and Vaishali on 14 July 2011. The main route was extended once more on 9 March 2019, when 6.67 km from Noida City Centre to Noida Electronic City opened with six new stations, among them Sector 52 Noida and Sector 62 Noida.
How the service works
Trains from Dwarka Sector 21 run through to either Noida Electronic City or Vaishali, and platform signs at Rajiv Chowk show both destinations; between the two branches you change at Yamuna Bank. On the trunk from Dwarka-Kakrola to Yamuna Bank, where both services run, DMRC gives an average interval of 2 min 51 s in the weekday peak and 3 min 30 s off-peak. Each branch beyond Yamuna Bank has a train every 5 min 42 s in the peak and 7 minutes off-peak, and the Dwarka Sector 21 end 4 min 16 s and 5 min 15 s. On weekdays the first trains leave the four ends between 06:00 and 06:24 and the last between 22:50 and 00:08; counting intermediate stations, departures run from 05:25 to 00:40.
