Several long trains are composed of two to three classes of travel, such as a 1st and 2nd classes which have different pricing systems for various amenities. The 1st Class refers to coaches with separate cabins, coaches can be air-conditioned or non air-conditioned.
Further, other AC classes can have 2 or 3 tier berths, with higher prices for the former, 3-tier non-AC coaches or 2nd class seating coaches, which are popular among passengers going on shorter journeys.
In air-conditioned sleeper classes passengers are provided with sheets, pillows and blankets. Meals and refreshments are provided, to all the passengers of reserved classes, either through the on-board pantry service or through special catering arrangements in trains without pantry car. Unreserved coach passengers have options of purchasing from licensed vendors either on board or on the platform of intermediate stops.
The amenities depend on the popularity and length of the route. Lavatories are communal and feature both the Indian style as well as the Western style.
