Vande Bharat Sleeper is undergoing trials at various speeds, both loaded and unloaded. Tests are being conducted on its braking system, air suspension, and coupler force. The train is likely to join the commercial operations soon.

Vande Bharat Sleeper trains entered the last round of trials. The sleeper trains of the Vande Bharat Express series are likely to be operational this month but the official date is yet to be announced.

Chennai's first Vande Bharat Express with sleeper coaches is launching soon, but reduced speed due to weight modifications.
