The cabins in the 1st AC compartment are typically private and have a locking door, ensuring a high level of privacy and security. Each cabin usually accommodates two or four passengers, depending on the train and the layout of the compartment. The cabins are equipped with comfortable berths, individual reading lights, charging points, and storage space for luggage. The 1st AC compartments are air-conditioned, providing a pleasant and cool environment during the journey. Passengers in this class are also provided with bedding, pillows, blankets, and towels. Meals are usually included in the fare, and they are served to passengers either in their cabins or in a dedicated dining car.
