Delhi Metro Train Interior Branding involves placing branded panels inside metro coaches to engage daily commuters in a high-dwell, clutter-free environment. Branding appears on surfaces like side and wall panels, ensuring continuous visibility. Available lines include Red (Line 1 – 8 coaches), Yellow (Line 2 – 8 coaches), Blue (Lines 3 & 4 – 8 coaches), Green (Line 5 – 4 coaches), Pink (Line 7 – 6 coaches) and Magenta (Line 8 – 6 coaches). #Orange/Airport Express (Line 10 – 6 coaches) Booking by individual coaches isn’t possible — you need to book the entire train through the full-train branding media option, Grey and Violet lines are currently on tender and will be available post DMRC approval.
