May i know what is the diferrence between soft berth and VIP room? Thanks

For soft sleeper, these are private compartments which are fitted out to a higher standard. Each compartment has four bunks - two upper and two lower. A door separate the compartment from the aisle to keep quiet and comfort. Quality bedding and pillows are provided. Each bunk is equipped with a small reading lamp. Temperature controls are installed alongside the door. As to the Luxury Soft Sleeper, this is the top level sleeper and the most expensive ticket but only equipped by a few of trains. There are only two comfortable bunks in a compartment, which is equipped with an independent toilet, sofa, tea table, TV and some other facilities equal to a soft sleeper. The price is about twice as much as that of a soft sleeper.
