अलग-अलग बर्थ के प्रकार — LB, UB, MB, SL, SU क्या हैं?

Each sleeper / AC coach has bays of 6 berths plus 2 side berths along the corridor.

Main bay (3 + 3):

• LB Lower Berth — bottom
• MB Middle Berth — folds down at night
• UB Upper Berth — top

Side berths (along corridor):

• SL Side Lower — bottom
• SU Side Upper — top

Preference tips:

• Elderly / pregnant: choose Lower
• Light sleepers: avoid Middle (folds down at night, less headroom during day)
• Privacy: Upper is best (no daytime traffic)
• Side berths are narrower than main berths.
