Bangladesh Railway Seat Plan — Coach Layout, Classes & How to Pick the Right Seat
Booking a Bangladesh Railway ticket and then staring at a confusing string of letters — S_CHAIR, F_SEAT, AC_B, SNIGDHA — is a genuinely common moment of confusion. The seat map shows you green and red boxes without much explanation of what you are actually choosing, and by the time most people figure out the difference between classes, they have already paid for the wrong one. This guide breaks down what each class actually looks like inside the coach, how the seats are arranged, and which one makes sense for your specific journey.
Before choosing your seat, make sure you can access the official booking system. If you are signing in for the first time, read our Bangladesh Railway eTicket Login guide to learn how to access your account safely.

Every Seat Class Explained — What the Codes Actually Mean
This Bangladesh Railway seat plan covers every class on the network. The codes you see on the booking page are abbreviations of the actual class names, and they are not always intuitive on first read. Here is the full breakdown, from most basic to most premium:
Quick Reference — AC, Sleeping & Charging at a Glance
The Bangladesh Railway Seat Plan makes it easier to compare different coach classes before booking. By understanding the seating layout in advance, you can choose the option that best matches your comfort, budget, and travel needs.
| Class | AC | Sleeping | Charging Point |
| AC Berth | Yes | Yes | Yes — at every berth |
| AC Seat | Yes | No | Yes — at every seat |
| Snigdha | Yes | No | Yes — at every seat |
| First Class Berth | No | Yes | Rarely available |
| First Class Seat | No | No | Rarely available |
| First Class Chair | No | No | Rarely available |
| Shovan Chair | No | No | Not provided |
| Shovan | No | No | Not provided |
| Shulov | No | No | Not provided |
Charging points are one of the more practical differences between classes that this seat plan needs to flag clearly — every AC class (Snigdha, AC Seat, AC Berth) comes with a power socket at or near your seat, while non-AC classes generally do not. If you are travelling with a phone you need to keep charged for tracking, tickets, or photos, this alone can be worth paying for.
Every Bangladesh Railway Seat Plan includes different travel classes, each designed for specific budgets and journey types. Understanding these classes before booking helps you avoid confusion when selecting your seat.
Full Class Breakdown
| Code | Class Name | What It Actually Is |
| SHULOV | Shulov | Unreserved wooden bench. No seat assignment — first come, first seated. Cheapest fare on the network. |
| SHOVAN | Shovan | Basic reserved seating, slightly more comfortable than Shulov but still without cushioning on most coaches. |
| S_CHAIR | Shovan Chair | Reserved, fan-cooled, cushioned reclining chair. Arranged 2+3 across the coach. The most commonly booked class. |
| F_SEAT | First Class Seat | Non-AC, cushioned seat arranged 2+3 across the coach on broad gauge lines. A step up in comfort from Shovan Chair, still no air conditioning. |
| F_CHAIR | First Class Chair | Non-AC open coach with cushioned chair seating, generally 5 seats per row on broad gauge trains. |
| F_BERTH | First Class Berth | Non-AC sleeper compartment. Same cabin layout as AC Berth but without air conditioning — a budget-friendly overnight option. |
| SNIGDHA | Snigdha | Air-conditioned reclining chair, arranged 2+2 open-plan across the coach. Widely considered the best value class for longer day journeys. |
| AC_S | AC Seat | Air-conditioned cabin seating. More private than Snigdha but seated rather than sleeping. |
| AC_B | AC Berth / AC Cabin | Fully air-conditioned sleeper compartment. Closed cabins of 4 to 8 berths. The most premium class on the network. |
Snigdha coaches run on most of the major intercity names you would recognise — Subarna Express on the Chittagong line, Parabat Express to Sylhet, Silk City Express to Rajshahi, and Sundarban Express to Khulna among others. Not every train carries every class, so check the specific train’s available classes on the booking page before assuming Snigdha or AC Berth will be an option.
Shovan Chair — Layout and What to Expect
This is the seat class most passengers end up booking, and for good reason — it covers the largest share of seats on most intercity trains and is reserved, meaning your seat is guaranteed for the journey. The coach is arranged in a 2+3 configuration across the width, with a central aisle separating a two-seat row from a three-seat row.
Shovan Chair — 2+3 Layout
Two seats one side, three the other. The middle seat has no window.
Most coaches seat around 60 to 80 passengers in this class. There is no air conditioning, but ceiling fans run throughout the journey. The seats recline slightly and have a fold-down tray, but legroom is tighter than Snigdha or First Class. For journeys under 3 hours, this is a perfectly reasonable choice — it is genuinely uncomfortable mainly on longer overnight runs.
Snigdha (AC Chair) — Layout and What to Expect
Snigdha is the class most regular travellers consider the sweet spot — properly air-conditioned, more legroom than Shovan Chair, and arranged in an open 2+2 configuration rather than 2+3. That single difference — one fewer seat per row — makes a noticeable difference to how cramped the coach feels.
Snigdha — 2+2 Layout
Two seats each side of the aisle. Every seat is window or aisle.
Seats recline further than Shovan Chair, the air conditioning is consistent throughout the journey, and most Snigdha coaches on newer rolling stock — Subarna Express, Sonar Bangla Express, and similar — have a small TV screen at the front of the coach. For any journey over 3 hours, especially in summer, the price difference between Shovan Chair and Snigdha is genuinely worth paying.
When comparing different coach classes, the Bangladesh Railway Seat Plan clearly shows why many passengers prefer Snigdha for longer journeys. The extra space and 2+2 seating layout provide a more comfortable travel experience.
AC Berth / AC Cabin — Layout and What to Expect
The Bangladesh Railway Seat Plan is especially helpful when comparing AC Berth, Snigdha, and Shovan Chair. Understanding how each coach is arranged makes it much easier to choose the right travel class before completing your booking.
This is the only class structured around closed cabins rather than open rows. Each cabin seats between 4 and 8 people depending on the train and configuration, with the seats converting into sleeping berths for overnight journeys. During the day, the same compartment functions as a private seating area; at night, the lower berths convert flat and upper berths fold down.
| How AC Berth Cabins Are Structured 4-berth cabin — two lower berths facing each other, two upper berths above. The most common configuration for families or couples wanting privacy. 6 to 8-berth cabin — larger compartment, sometimes shared between passengers who do not know each other if you book individual berths rather than the whole cabin. Booking the full cabin — if travelling as a family or group of 4, booking all the berths in one cabin gives you complete privacy for the journey. This is significantly more expensive than booking individual seats but worth it for overnight family travel. Single berth booking — booking just one or two berths in a cabin means you may share with strangers. This is normal and safe, but worth knowing in advance if privacy matters to you. |
AC Berth is not air-conditioned on every train — some First Class Berth (F_BERTH) coaches offer the same cabin layout without AC, at a lower price. If the train you are booking shows both AC_B and F_BERTH as options, the difference is purely the air conditioning, not the cabin structure.
Which Class Should You Actually Book? — Using This Seat Plan to Decide
The honest answer depends entirely on journey length, time of day, and budget. Here is a straightforward way to decide:
| Situation | Best Class | Why |
| Short trip, under 2 hours | Shovan Chair | No real benefit to paying more for a brief journey. Fan-cooled is fine. |
| Day trip, 3 to 6 hours | Snigdha | AC and 2+2 layout make a real difference over several hours. Worth the extra cost. |
| Overnight journey | AC Berth (or First Class Berth on a budget) | You actually need to lie down to sleep properly — chair classes are not designed for this. |
| Travelling with family, want privacy | AC Berth — book full cabin | Closed compartment means no strangers, and children can move around more freely. |
| Tight budget, distance does not matter | Shovan or Shulov | Lowest fare on the network. Acceptable if comfort is not the priority. |
| Solo traveller wanting AC without high cost | Snigdha | Better value than booking an entire AC cabin alone. |
Reading the Seat Plan — How to Pick the Right Seat Online
Before confirming your booking, always check the Bangladesh Railway Seat Plan carefully. The official seat map allows you to see available seats, coach layouts, and seating arrangements so you can choose the most comfortable option.
The online seat map at eticket.railway.gov.bd shows every seat in your selected class as a coloured box — green for available, red for taken. What it does not always make obvious is which seats are window, aisle, or middle. Here is how to read it:
After selecting your seat, you can use our Bangladesh Railway PNR Status Check guide to confirm that your booking has been successfully recorded before your journey.
Frequently Asked Questions
| Q1: What is the difference between Snigdha and Shovan Chair? A: Snigdha is air-conditioned and arranged 2+2 across the coach, giving every passenger a window or aisle seat with more legroom. Shovan Chair is non-AC, fan-cooled, and arranged 2+3, which means some seats are in the middle with no window access. Snigdha costs more but is considerably more comfortable for journeys over 3 hours. |
| Q2: How many seats are in an AC Berth cabin? A: AC Berth cabins typically hold either 4 or 8 berths depending on the train and coach. A 4-berth cabin has two lower and two upper berths facing each other. Booking the entire cabin gives you complete privacy; booking individual berths may mean sharing with other passengers. |
| Q3: What does S_CHAIR mean on the booking page? A: S_CHAIR is the short code for Shovan Chair — the standard reserved, fan-cooled, cushioned seat class found on most intercity trains. It is arranged 2+3 across the coach and is the most commonly booked class on Bangladesh Railway. |
| Q4: Is First Class Seat better than Shovan Chair? A: First Class Seat (F_SEAT) is non-AC but offers more comfortable cushioned seating than Shovan Chair, with a similar 2+3 layout. It sits between Shovan Chair and Snigdha in terms of comfort, without the air conditioning that Snigdha includes. |
| Q5: Can I book an entire AC Berth cabin for my family? A: Yes. When selecting AC Berth on the booking page, you can select all the berths within a single cabin — typically 4 — to ensure your family or group has complete privacy for the journey rather than sharing with other passengers. |
| Q6: What is the difference between AC Berth and First Class Berth? A: Both have the same closed-cabin sleeper layout with upper and lower berths. The difference is air conditioning — AC Berth (AC_B) is air-conditioned, while First Class Berth (F_BERTH) is the same cabin structure without AC, at a lower fare. |
Choosing Comfort to Match Your Journey
Choosing the right Bangladesh Railway Seat Plan depends on your travel distance, budget, and comfort preferences. Spending a few extra minutes comparing the available classes can make your journey much more enjoyable.
There is no single correct seat class on this Bangladesh Railway seat plan — only the right one for the specific trip you are making. A two-hour daytime hop barely justifies Snigdha pricing, while a seven-hour overnight run in Shovan Chair is a genuinely tiring way to travel when AC Berth exists for exactly that situation. Match the class to the journey length and time of day, and the booking page stops being a wall of confusing codes and starts being a straightforward decision.
