Bangladesh Railway offers several seat and berth categories, and each one is priced and designed differently. Picking the right class can make the difference between a relaxing journey and an uncomfortable one — especially on long routes like Dhaka to Chattogram or Dhaka to Sylhet. This guide breaks down every seat class in plain language, so you know exactly what you’re booking before you pay.

AC vs Non-AC: The Two Broad Categories
Before looking at individual seat types, it helps to understand the two main groups they fall under.
Air-Conditioned (AC) classes are climate-controlled, generally more spacious, and cost more than their non-AC counterparts. They’re a good choice for summer travel, overnight trips, or anyone who prioritizes comfort over price.
Non-AC classes rely on natural airflow through windows and ceiling fans. They’re more affordable and still perfectly comfortable for shorter or daytime journeys, especially in cooler months.
Neither category is “better” in an absolute sense — the right choice depends on your route, travel time, budget, and personal comfort preference.
Seat & Berth Classes Explained
AC-B (AC Berth)
This is the top-tier sleeping arrangement on Bangladesh Railway. AC-B cabins have proper berths (beds) inside an air-conditioned compartment, usually shared among 2 to 4 passengers per cabin. It’s the preferred option for overnight travel on longer routes, since you can actually lie down and sleep instead of sitting upright for hours.
Best for: Overnight journeys, families or groups who want privacy, travelers who value comfort over cost.
AC-S (AC Seat)
AC-S offers the same air-conditioned comfort as AC-B, but with upright seating instead of berths. It’s built for daytime travel where sleeping isn’t necessary, but a cool, comfortable cabin still matters.
Best for: Daytime trips on hot days, business travelers, anyone wanting AC comfort without paying for a sleeping berth.
Snigdha (AC Chair)
Snigdha sits in its own category — it’s an AC chair coach, but with a more modern seating layout than AC-S, cushioned reclining chairs, and generally a newer coach design. Many passengers consider it the most comfortable seated (non-berth) option on the network.
Best for: Travelers who want AC comfort at a slightly lower cost than a full cabin, and don’t mind sitting in an open chair-coach layout rather than a private cabin.
F-Berth (First Class Berth)
F-Berth gives you the sleeping-berth experience of AC-B, but without air conditioning. Compartments are still private cabins with proper beds, just relying on fans and open windows for airflow.
Best for: Overnight travelers on a tighter budget who still want a private cabin and a real bed, and who don’t mind non-AC conditions — especially during the cooler months of the year.
F-Seat (First Class Seat)
The seated, non-AC version of First Class. You get a cabin-style compartment with proper seating, more legroom and privacy than the general chair coaches, but without climate control.
Best for: Daytime travelers who want a quieter, more private compartment than an open chair car, without paying for AC.
F-Chair (First Class Chair)
F-Chair is an open (non-cabin) coach, but with higher-quality, more comfortable chairs than the standard Shovan Chair. Think of it as a step up in comfort while still being fully non-AC.
Best for: Travelers who want better seating than the standard economy chair, on a moderate budget.
S-Chair (Shovan Chair)
S-Chair is the standard non-AC seating option most passengers use for everyday travel. Seats are reasonably comfortable and arranged in an open coach layout, without the cabin privacy of First Class.
Best for: Regular commuters and budget-conscious travelers making shorter or medium-length trips.
Shovan
Shovan seating is similar to S-Chair but generally found in older or more basic coaches, with simpler bench-style or fixed seating. It’s a reliable, no-frills option for point-to-point travel.
Best for: Short-distance trips where comfort is a lower priority than cost.
Shulov
Shulov is the most basic and most affordable seating class on Bangladesh Railway — simple wooden or hard-bench seating without cushioning. It’s mainly used on local and short-haul routes.
Best for: Very short trips and travelers looking for the lowest possible fare.
How to Choose the Right Seat Class
- Traveling overnight? Go for AC-B or F-Berth so you can actually sleep instead of sitting up all night.
- Traveling in peak summer heat? Prioritize an AC class (AC-B, AC-S, or Snigdha), especially on longer routes.
- Traveling with family or young children? A berth class or First Class cabin gives more privacy and space to move around.
- Traveling on a tight budget? S-Chair, Shovan, or Shulov will get you there at the lowest cost, and are perfectly fine for shorter trips.
- Traveling for business, need to work or rest briefly during the day? Snigdha or AC-S strike a good balance between comfort and cost.
