Your ticket shows codes like "B1, 34, LB" — and knowing what they mean helps you find your coach and berth fast. Here is the decoder.

Coach Codes — Which Coach You're In

The letter (with a number) tells you the class and coach:

• SL — Sleeper class (e.g. S1, S2, S3...). "S3" means Sleeper coach 3.
• B — 3AC (Three-tier AC): B1, B2, B3...
• A — 2AC (Two-tier AC): A1, A2...
• H / HA — 1AC (First AC) or First+2AC composite.
• C / CC — AC Chair Car: C1, C2...
• D / E — Second Seating (2S) / Executive Chair Car.
• M / G — Pantry / General (unreserved) coaches.

So S3 = Sleeper coach 3, B2 = 3AC coach 2, A1 = 2AC coach 1.

Berth Codes — Which Berth You Get

The berth type tells you where you sleep/sit:

• LB — Lower Berth
• MB — Middle Berth
• UB — Upper Berth
• SL — Side Lower (also used for RAC)
• SU — Side Upper
• WS / WL — Window Side (in chair cars)

For example, "B1, 34, LB" = 3AC coach 1, berth 34, a Lower Berth.

Finding Your Coach at the Station

Coaches are arranged in a set order along the platform. To find where your coach stops, check the coach position display or read how to find your coach at the station. Reach the right spot before the train arrives, as stops are brief.

Where to See These Codes

Your coach and berth appear on your ticket and PNR after booking (and after RAC/WL confirms). Check them on our PNR status tool, and learn to read the whole ticket in how to read your train ticket.

Bottom line: the coach code (SL/B/A/H/C) tells you the class and coach number, and the berth code (LB/MB/UB/SL/SU) tells you your berth type — together they pinpoint exactly where to sit or sleep.

Frequently Asked Questions

What does B1, S3, or A1 mean on a train ticket?

The letter is the class and the number is the coach. S3 is Sleeper coach 3, B1 is 3AC coach 1, and A1 is 2AC coach 1.

What do LB, MB, UB, SL and SU mean?

They are berth types: LB is Lower Berth, MB Middle Berth, UB Upper Berth, SL Side Lower, and SU Side Upper. RAC is usually allotted on a side-lower berth.

What does SL mean — Sleeper or Side Lower?

SL is used both for Sleeper class (as a coach class) and for a Side Lower berth (as a berth type). Context on your ticket tells you which — a coach like S3 vs a berth code.

How do I find my coach at the station?

Check the coach position display on the platform, which shows the order of coaches. Reach your coach's spot before the train arrives, as stops are short.
