Audio ads with a duration of 10 seconds (which can extend up to 20 seconds) will be played on 6 active metro trains. The ads will only start playing once the train departs from the source station. The available ad options cover a total of 11 stations, with approximately 11-12 trip journeys per day per train, starting from Badarpur Border to Kashmere Gate and vice versa. Ads for one brand will be played when the train reaches the first station after the source station. And the next ad will be played alternatively with a gap of one station between each brand ad.
