Side Upper tips · काम की बातें

  • More privacy than a main upper berth
  • Good for solo travellers on shorter journeys
  • Near the toilet - expect smell and foot traffic
  • Near the door - more crowd at every stop
Newer LHB 3E rakes carry 83 berths and add a Side Middle berth, which shifts the numbering. This layout is the 72-berth variant.
