The 12933 / 12934 Karnavati Superfast Express is one of four express trains belonging to Indian Railways that offer Chair Car services between Ahmedabad Junction (ADI) and Mumbai Central (MMCT) in India.

The conventional rakes were replaced by Linke-Hofmann Busch (LHB) coaches for this train in 2014.

As with most train services in India, coach composition may be amended at the discretion of Indian Railways depending on demand.

Prior to Western Railways switching over to the AC system in February 2012, dual-traction WCAM-1 or WCAM-2/2P locos would haul the train.

Note:- No Halt for Maninagar as 12934 Ahmedabad–Mumbai Central Karnavati Superfast Express
