The planned expansion of the Delhi Metro under Phase V(b) is set to add 97 kilometers and 65 stations across seven new corridors, a significant undertaking with an estimated cost of ₹48,204.56 crore. While the project promises to extend transit services to Delhi's outer areas, its ambitious scale is prompting scrutiny of the Delhi Metro Rail Corporation's (DMRC) financial capacity, especially given existing debts and a history of project cost increases.
Project Cost and DMRC's Financial Health
The Phase V(b) plan includes seven new corridors, spanning 97 kilometers and adding 65 stations, at a projected cost of ₹48,204.56 crore. This significant investment is designed to improve last-mile connectivity and reduce travel times to Delhi's outer regions. Historically, metro expansions have spurred economic activity and increased property values nearby. However, the Delhi Metro Rail Corporation (DMRC) faces a challenging financial environment. For the fiscal year ending March 31, 2025, DMRC reported revenues of ₹8,150 crore. Despite this, the corporation is burdened by substantial debt, significant losses in recent years, and ongoing loan repayments. Factors like the COVID-19 pandemic and loans from agencies such as JICA have compounded these financial pressures. The Delhi government's commitment is evident in its revised FY27 transport budget, which allocates ₹2,885 crore for metro expansion, including Phase IV and V.
Prioritizing Corridors, Balancing Costs
Four of the seven corridors are prioritized for completion by 2029, aiming to connect areas like Najafgarh, Narela, and Mithapur. These new lines are expected to stimulate real estate development and commercial activity. However, the financial sustainability of adding more track, particularly given the varying costs per kilometer in India (₹250-300 crore for elevated, ₹500-600 crore for underground), is a key concern. The substantial investment required for these mixed elevated and underground segments must be evaluated against DMRC's existing financial commitments.
Project Hurdles: Delays, Overruns, and Risks
Past metro projects in India, including Delhi Metro's own Phase IV, show a pattern of delays and cost escalations. Some Phase IV corridors faced delays of up to three years, pushing costs up by about 15% from initial estimates. The ambitious scale of Phase V(b), with extensive tunneling and construction, carries risks of unexpected geological issues, land acquisition challenges, and rising material and labor costs. These factors can lead to significant budget overruns. DMRC's financial stability, already strained by past deficits and loans from organizations like JICA, faces further pressure. Recent fare hikes, averaging 7% in August 2025, highlight the corporation's financial difficulties. The 2029 target for the first four priority corridors is ambitious, with potential for further delays that could increase overall costs.
Connecting Delhi's Periphery: Goals and Oversight
The goal of Phase V(b) is to extend Delhi Metro's reach, connecting more of the city's growing outer areas to its transit system. The government's increased capital expenditure for DMRC in FY26 suggests a focus on fast-tracking infrastructure development. While this expansion promises improved urban mobility and balanced development, its successful execution will be key. The strategy of prioritizing certain corridors aims to manage financial and logistical challenges. However, given the history of delays and cost overruns, strong oversight and financial management will be essential to ensure the project benefits Delhi without overburdening public finances or DMRC.
