Indian Railways Classes Explained: 1A, 2A, 3A, 3E, SL, CC, EC and 2S
Last updated 10 October 2026
The class codes on an Indian train ticket tell you a lot: whether you will sleep or sit, whether the coach is air-conditioned, how many people share your bay, and whether bedding is provided. This guide covers each class, then suggests which one to book for different kinds of trip.

Not every train has every class. Where our data includes it, a train's page on Railzy lists the classes that train runs with. Otherwise the IRCTC booking page shows them.
Sleeper classes
First AC (1A) is the top class. Berths are in lockable cabins of two or four, so you get real privacy. It is offered on fewer trains than other classes, has the fewest passengers per coach, and is the most expensive.
AC 2-Tier (2A) has bays of four berths (two lower, two upper) plus two side berths along the aisle, with curtains instead of doors. With no middle berth there is more headroom and the lower berth makes a comfortable seat during the day. Many families pick it for overnight trips.
AC 3-Tier (3A) has bays of six berths (lower, middle and upper on each side) plus two side berths. It is the most commonly booked AC class and good value for overnight journeys. The middle berth folds down during the day so the lower berth can be used as a seat.
AC 3-Tier Economy (3E) follows the 3A layout but fits more berths into each coach, so there is a little less space per passenger. It is priced below 3A.
Sleeper (SL) has the same six-plus-two bay layout as 3A, but without air-conditioning. It has fans and windows that open. Bedding is not provided, so bring a sheet or shawl. It is the cheapest way to get a berth for an overnight trip.
Seating classes
Executive Chair Car (EC) has wide reclining seats arranged 2 + 2. It runs on day trains such as Shatabdi and Vande Bharat.
AC Chair Car (CC) has reclining seats arranged 3 + 2. It is the standard AC class on day trains, and a good fit for journeys of a few hours.
Second Sitting (2S) has reserved non-AC bench-style seats. It is the cheapest reserved class and common on short intercity routes.
General / Unreserved (GN or UR) has no reservation. You buy a ticket at the counter or through the UTS app and take any free space. Seats are not guaranteed and coaches can be very crowded on busy routes.
Berth codes on your ticket
| Code | Berth | Worth knowing |
|---|---|---|
| LB | Lower berth | Easiest to reach. During the day it is the shared seat for the bay. |
| MB | Middle berth | 3A, 3E and SL only. It folds down during the day and is usually raised only at night. |
| UB | Upper berth | Most privacy and no daytime disturbance, but a climb. |
| SL | Side lower | Along the aisle. RAC passengers share this berth. |
| SU | Side upper | Along the aisle. Shorter than the main berths in some coaches. |
Note that SL means Sleeper *class* in the class column and side lower *berth* in the berth column. The column it appears in tells you which.
Indian Railways keeps a lower berth quota. Lower berths are allotted where available to senior citizens, women aged 45 and over, and pregnant women, even if they did not ask for one. A lower berth is not guaranteed if none are left.
Which class should you book?
| Trip | Usually the best fit | Why |
|---|---|---|
| Overnight, on a budget | SL | A full berth for the night at the lowest price |
| Overnight, in summer | 3A or 3E | Air-conditioning makes a big difference in hot months |
| Overnight, family or elderly travellers | 2A | More headroom, no middle berth, curtains for privacy |
| Overnight, privacy matters most | 1A | Lockable cabin |
| Daytime, a few hours | CC or 2S | You do not need a berth for a day trip |
| Daytime, longer or business travel | EC | Wider seats, quieter coach |
Price and availability usually decide in the end. To see which trains run between your stations and when they depart, use trains between stations. Our fare guide explains why prices differ.
Frequently asked questions
What is the difference between 3A and 3E?
3E (AC 3-Tier Economy) uses the same three-tier layout as 3A but fits more berths into each coach, so there is slightly less space per passenger. It is priced below 3A.
Is bedding provided in Sleeper class?
No. Bedding is provided in AC sleeper classes (1A, 2A, 3A) but not in Sleeper (SL), so carry your own sheet or shawl.
What is the difference between CC and EC?
Both are AC seating classes on day trains. CC (AC Chair Car) has 3 + 2 seating; EC (Executive Chair Car) has wider 2 + 2 seating and costs more.
Which berth is best in 3A or Sleeper?
It depends on the trip. The lower berth is easiest to reach but doubles as the shared seat during the day. The upper berth gives the most privacy and can be used any time. The middle berth can usually be raised only at night.
Do senior citizens get a lower berth automatically?
Indian Railways has a lower berth quota for senior citizens, women aged 45 and above, and pregnant women, and allots lower berths to them where available. It is not guaranteed if none are left.
