what does cnf s6 36 lb ss means in train

“CNF S6 36 LB SS” on a train ticket is a compact way of saying: your seat/berth is confirmed , you are in coach S6 , on seat/berth 36 , in the lower berth (LB) of a side‑lower (SS) seat arrangement, typically in a Sleeper-class coach.

Quick breakdown of each part

Code| Meaning in Indian Railways context
---|---
CNF| Confirmed – your reservation is confirmed and you are guaranteed a berth/seat 235.
S6| Coach number – you should look for the coach marked S6 on the platform (S-series coaches are usually Sleeper class) 48.
36| Seat/berth number – your assigned position inside that coach is 36 48.
LB| Lower Berth – within a 3‑berth side bay, you are on the lower seat, not middle or upper 4.
SS| Side Lower – specifically indicates a side bay (next to the corridor) lower berth, as opposed to main bay lower berth 48.

So if your ticket says something like:

CNF/S6/36/LB/SS

You can read it as:

“Your ticket is confirmed; go to coach S6, find berth 36, which is the lower berth in a side‑lower position.”

What this means for your journey

• You do not need to wait for charting to get your seat number; it is already shown.

• On the day of travel, check the coach position chart at the station (often displayed near the platform) to see where S6 is located relative to the engine and other coaches.
• Inside S6, look for the berth number tag (usually on the side of the seat/berth) and confirm it is 36.
• Since it’s LB/SS , you’ll be on the lower side berth, which is more convenient for older passengers or those who don’t want to climb up.

This format is standard on Indian Railways reserved tickets (especially Sleeper class) and is used to clearly tell passengers:

• whether the ticket is confirmed,
• which coach they are in,
• which exact berth/seat,
• and what type of berth (lower/middle/upper, side/main).
