Thodari (2016)

Poochiyappan works in the pantry car of a long-distance express from Delhi to Chennai. On board he meets Saroja, a hairdresser travelling with a film actress, who dreams of becoming a playback singer, and he does everything he can to impress her, including pretending to have contacts in the film industry. Then a series of mishaps leaves the engine racing out of control with hundreds of passengers on board, while officials, the media and the police argue over what to do. Thodari ("train") is Prabhu Solomon's attempt at a disaster thriller wrapped around a light romance, with most of the action set on and around the speeding train. D. Imman wrote the songs, and the film paired Dhanush with Keerthy Suresh for the first time.
