DMRC To Boost Revenue With In-Train Audio Ads Across Four Metro Lines

The Delhi Metro Rail Corporation is set to expand its in-train audio advertising network by introducing commercial audio slots across four of its busiest metro corridors as part of efforts to strengthen non-fare revenue streams.

The rollout will cover the Red, Yellow, Blue and Magenta lines, building on a pilot launched on the Violet Line in December 2023. Advertisements will be played only during silent intervals between operational announcements, with passenger information and safety messages continuing to take priority.

To execute the initiative, DMRC has floated a tender inviting agencies to market, manage and operate audio advertisement inventory on six trains each across the four lines. Under the proposed revenue-sharing model, the corporation will receive 85% of the gross advertising revenue, while the selected agency will retain the remaining 15%.

The available advertising inventory varies across corridors, with the Red Line offering 721 seconds of audio inventory, followed by the Blue Line with 634 seconds, the Yellow Line with 596 seconds and the Magenta Line with 300 seconds. These routes collectively serve some of Delhi Metro's highest passenger volumes, making them attractive to advertisers seeking broad commuter reach.

DMRC has also stipulated that up to 5% of the available inventory on each train will be reserved for social and corporate social responsibility (CSR) messaging. In addition, participating agencies have been encouraged to develop campaigns that reflect Delhi's cultural identity while maintaining a non-intrusive commuter experience.

The expansion underscores DMRC's broader strategy to diversify revenue beyond ticket sales by leveraging its transit network as an advertising platform, while ensuring that commuter convenience and safety remain the primary focus.
