Delhi’s public transport network is entering another major growth phase in 2026, with multiple new corridors under construction and recently approved extensions set to reshape daily commuting across the National Capital Region. The Delhi Metro Rail Corporation’s ongoing Phase IV works, combined with fresh approvals under Phase V(A), signal a strategic expansion aimed not only at adding length to the network but also at strengthening interconnectivity, reducing congestion and improving access to key commercial and administrative hubs.
Phase IV construction has been progressing in stages, with priority corridors expected to be completed in phases through 2026. These corridors are designed to improve connectivity in underserved areas while easing pressure on some of the city’s most crowded routes. Officials have indicated that commissioning will happen in segments rather than as a single large launch, depending on civil work completion, systems integration and mandatory safety clearances.
One of the most closely watched developments is the extension linked to the Janakpuri West–R.K. Ashram Marg corridor. Sections of this corridor have already been operationalised earlier, while additional stretches are moving toward readiness. A key elevated segment between Deepali Chowk and Majlis Park is reported to be nearing launch, a development that is expected to offer relief along the busy Outer Ring Road corridor. This stretch will connect residential clusters in northwest Delhi with existing interchange stations, enabling smoother transfers to other major lines.
The expansion is not limited to peripheral connectivity. In December 2025, the Union Cabinet approved three new corridors under Phase V(A), adding over 16 kilometres to the network. These extensions are intended to strengthen links within central Delhi and improve airport access.
The R.K. Ashram Marg to Indraprastha extension, spanning nearly 10 kilometres, is expected to enhance connectivity to the Central Vista and adjoining government districts. Proposed stations along this stretch include Shivaji Stadium, Central Secretariat, Kartavya Bhawan, India Gate, War Memorial–High Court, Baroda House, Bharat Mandapam and Indraprastha. The project is aimed at reducing road congestion in the heart of the capital and creating seamless interchange opportunities with existing metro lines.
Another approved extension connects Aerocity to Indira Gandhi International Airport Terminal 1, improving access to the domestic terminal and strengthening multimodal connectivity for air travellers. The third extension, from Tughlakabad to Kalindi Kunj, includes stations such as Sarita Vihar Depot and Madanpur Khadar. These links are expected to benefit commuters in southeast Delhi and integrate residential and institutional areas more efficiently into the metro network.
A significant feature of the new expansions is the focus on interchange stations. With additional interchanges planned under Phase IV and Phase V(A), Delhi Metro’s network design is evolving toward shorter transfer times and more direct travel routes. Central Secretariat, in particular, is projected to emerge as a triple interchange hub once the new extensions are completed, allowing commuters to switch lines with minimal walking and reduced travel delays.
Beyond route length and station count, the 2026 expansion also reflects technological and passenger-centric upgrades. Upcoming sections are being equipped with Communication-Based Train Control systems to support higher operational efficiency. Features such as platform screen doors, energy-efficient LED lighting, regenerative braking systems and improved accessibility infrastructure, including tactile pathways and wheelchair-friendly facilities, are being incorporated into new stations.
For daily commuters, the benefits are expected to be tangible. Reduced travel times across north, west and central Delhi corridors could encourage a shift away from private vehicles, easing traffic congestion on arterial roads. Improved airport connectivity will benefit both business travellers and tourists. Enhanced interchange capacity will make cross-city journeys more predictable and less time-consuming.
While timelines are aligned with staged completion through 2026 and into 2027 for certain corridors, metro authorities have maintained that commissioning depends on successful testing, regulatory approvals and safety certification. As with previous expansion phases, sections may open incrementally once they meet operational standards.
Delhi Metro’s continued growth underscores its role as the backbone of the capital’s urban mobility strategy. With each phase, the network moves closer to becoming a fully integrated system that connects residential neighbourhoods, commercial centres, government institutions and transport hubs in a more cohesive manner. The 2026 route expansion is less about dramatic one-day launches and more about steady, structural improvements that are expected to reshape commuting patterns for years to come.
