I have seen a lot of new members asking about different classes of train travel and I dont blame them for asking because our railway system is a bit too complex and not very easy to understand. I am going to explain briefly what the different ticket classes are and what they mean. These are the different travel classes in India along with their codes that are printed on tickets : First class Air-Conditioned (1A) This one is a coupe (cabin) which has 4 beds, some cabins come with two beds too. These cabins have a door that can be locked from inside and gives you complete privacy provided you have all the 4 or in some cases 2 seats. There are electric sockets for charging mobile phones and laptops etc.These tickets are the costliest of the lot and some times may cost as much as an air ticket for the same distance. AC 2-tier sleeper (2A) This one does not have a door and costs half almost half the price of a first class ticket. Not bad for the price. These are bunk beds which can be pulled to make a seat during the day and there are two tiers of bunk beds. AC 3 Tier (3A) Similar to the above but this one has three tiers of bunk beds on one side and on the other end there are two bunk beds which makes you share the same space with more people. The price reflects this difference very well. This class is also air conditioned and is the cheapest ticket available if you want air conditioning with sleeping arrangements. AC chair Car (CC) AC chair car is popular among those travelers who travel short distances. There are three seats on each side and in some trains food is also served like Shatabdi express trains. Sleeper Class (SL) Sleeper class is very similar to AC 3 tier but without the air conditioning. General or Unreserved This is the cheapest ticket available and you do not get a reserved seat with a general ticket. There can be a lot of people in those general coaches and none of them has a reserved seat so it is pretty much a free for all battle to get your bum on one of the flat benches some how. These coaches are normally very crowded and at times you would find it hard to get in and out too. This sums up the different travel classes we have in Indian railways. I hope I have not missed anything. Please feel free to add if I may have left something out.
