Delhi Metro Blue Line Route Map, Timings, Stations List & Fare 2025

The Delhi Metro Blue Line  is one of the busiest routes in Delhi and most important metro route in Delhi NCR.  It is a ‘massive lifeline‘ linking the ‘Dwarka sub-city’ in ‘West Delhi‘ with the major ‘NCR‘ zones of ‘Noida‘ and ‘Vaishali‘. This primarily ‘elevated‘ corridor is the definition of ‘seamless connectivity‘ for ‘Delhi‘ residents and students hitting up their colleges or office hubs.

The Blue Line of Delhi Metro consists of two corridors:

• Main Line (Line 3): The 56.6-km stretch from ‘Dwarka Sector 21‘ to ‘Noida Electronic City‘, covering 50 stations.
• Branch Line (Line 4):  An 8.5 km route from Yamuna Bank to Vaishali, with 8 stations.

It was the ‘longest metro line‘ until the ‘Pink Line‘ snagged the title, but the ‘Blue Line‘ remains crucial. It connects the ‘Central Business District (CBD)‘ (Connaught Place) to ‘Dwarka‘s residential areas’ and ‘Noida’s office hubs’. The ‘DMRC‘ is always working to improve it, planning to link the ‘Blue Line‘ with the ‘Noida Metro’s Aqua Line‘ for smooth travel between ‘Delhi‘, ‘Noida‘, and ‘Greater Noida‘.

Delhi Metro Blue Line: Quick Facts & Current Status 

The Blue Line is fully operational and is constantly integrated with new Phase 4 projects to ensure ‘enhanced connectivity‘.

Delhi Metro Blue Line Milestones (Operational Network in 2025)

The Delhi Metro Blue Line has expanded in multiple phases since its first stretch opened in 2005. Below is the complete breakdown of its operational network milestones — from Dwarka to Noida Electronic City and Vaishali, making it one of the longest and busiest corridors in Delhi NCR.

Blue Line Metro Expansion Highlights

• The Blue Line Phase 1 connected Dwarka’s residential hubs with Central Delhi’s commercial zones, easing daily commute traffic.

• Phase 2 expanded connectivity toward Noida and Ghaziabad, linking NCR to the Delhi Metro network.

• Phase 3 made Noida Electronic City a new terminal, improving access to IT parks and office districts.

• Future Phase 4 plans aim to integrate with the Aqua Line, enabling seamless Delhi–Noida–Greater Noida travel

Skywalk Connecting Blue Line and Aqua Line (2025 Update)

The Noida Metro Rail Corporation (NMRC) is introducing a state-of-the-art, air-conditioned skywalk that will seamlessly connect the Blue Line’s Sector 52 Metro Station with the Aqua Line’s Sector 51 Metro Station.

Spanning 420 metres, this elevated corridor will eliminate the need for passengers to exit and re-enter through separate gates, offering a hassle-free, ticketless interchange experience between the two major metro lines.

The project is expected to be fully operational by October 2, 2025, significantly improving travel convenience for commuters between Delhi, Noida, and Greater Noida.

Blue Line Metro Interchange Stations in Delhi NCR

The Delhi Metro Blue Line is one of the most well-connected corridors, providing multiple interchanges with other metro lines across the DMRC and NMRC networks. These interchange hubs ensure smooth connectivity between residential, commercial, and educational zones of the National Capital Region (NCR).

Why This Skywalk Matters

• Reduced commute time — No more road crossing or separate entry for Aqua Line.

• Improved passenger flow — Direct movement between Blue and Aqua Lines.

• Weather-proof travel — Fully air-conditioned with modern safety systems.

• Eco-friendly initiative — Encourages more metro usage, reducing road congestion.

Branch Line on Blue Line Route (Ghaziabad Link)

Stations like ‘Karkardooma‘, ‘Anand Vihar‘, ‘Kaushambi‘, and ‘Vaishali‘ are vital, linking ‘Ghaziabad‘s’ ‘localities‘ to the rest of the ‘Delhi Metro Network‘.

Blue Line Metro Upcoming Lines (Phase 4 & Beyond)

The Final Takeaway: Delhi Metro Blue Line

The Delhi Metro Blue Line is more than just a metro route—it is a key driver of economic growth and a symbol of sustainable urban mobility in Delhi NCR. By reducing traffic congestion, providing a reliable and cost-effective commuting option, and connecting residential, commercial, and business hubs, it serves as the lifeline for over 20.80 lakh passengers daily.
