A routine complaint about poor air conditioning on the Lucknow-Barauni Express led to the discovery of hundreds of whiskey bottles hidden in the AC duct of an AC-2 tier coach. The incident happened when passengers reported issues with the cooling system, prompting an unscheduled technical inspection stop. Railway technicians, inspecting the duct above berths 32 and 34, found the bottles wrapped in newspaper, obstructing airflow. The authorities confiscated the illicit liquor and conducted a thorough search of the coach to ensure no further contraband was hidden.
