what is 2s and cc in train

In Indian trains, 2S refers to the second seating class, which is the lowest reserved class in Indian trains. It is a seating class in which the seats are in the form of benches, and the seats may or may not possess a cushion. The seats in the 2S class can be joined or may have a little distance between them. This class does not offer air conditioning facilities to passengers, but it provides other basic amenities such as charging points, toilets, reading lights, fans, emergency exit windows, and sometimes a small table for passengers. The 2S class is generally preferred for short journeys of 4-5 hours, and it is a budget-friendly option for the major category of passengers. One should not confuse 2S with AC Chair Car in trains, which also offers seating facilities but with air conditioning.
