The makers of Vijay Sethupathi's upcoming film Train, directed by Mysskin, dropped the first single titled 'Kannakuzhikaaraa' on Tuesday.

The melody number that describes the heroics of the lead is composed by Mysskin, sung by Shruti Haasan, who plays the female lead, and penned by Kabilan. The lyrical video also featured behind-the-scenes footage from the film.

The time-bound thriller also stars Nassar, Narain, and Ira Dayanand, among others. Actor Narain is reuniting with Mysskin after over a decade. They have collaborated on films such as Anjathey (2008) and Mugamoodi (2012).

Filming for Train began in December 2023. A first look at the film was released in January 2025, which featured a glimpse of Mysskin's music for the film, sung by Shruti Haasan.

On the technical side, Fowzia Fathima is the cinematographer, and Sri Watson is the editor. Kalaipuli V Thanu is producing Train under his V Creations banner.

The film is yet to get a release date.
