Here’s a detailed guide to the 3 Tier AC Coach Seat Map in Indian Railways:

🚆 3 Tier AC (3A) Coach – Overview

The 3A coach (AC Three Tier) is an air-conditioned sleeper class offering a budget-friendly overnight travel option compared to 2A or 1A.

  • Fully air-conditioned
  • Berths, not seats only — meant for overnight travel
  • 6 berths per compartment + 2 side berths
  • Provides bedding (pillow, blanket, sheets)

🛏️ 3A Coach Layout

Each bay (compartment) has 8 berths arranged like this:

Main Section (per bay):
 _______________________
| UB | MB | LB     LB | MB | UB |
|____|____|____   ____|____|____|

Side Section:
 _______________________
|  SU     SL |
|___________|

UB = Upper Berth  
MB = Middle Berth  
LB = Lower Berth  
SU = Side Upper  
SL = Side Lower

Each compartment consists of:

  • 6 berths in the main bay (3 on each side, stacked vertically)
  • 2 side berths across the aisle
    → Total: 8 berths per bay

🔢 Berth Numbering in 3A

Seat/berth numbers typically go like this:

Bay No. Berth Numbers Layout
1 1, 2, 3, 4, 5, 6, 7, 8 1–6 = main bay, 7–8 = side
2 9–16 and so on…
  • Odd numbers are usually lower/middle berths
  • Even numbers are upper or side berths
  • Numbering varies depending on the coach build, but follows this general pattern
