I travelled by New Delhi-Lucknow Premium spl train (04434) on 27.9 and returned by same train next day.In sleeper class, there was no ticket checking staff or TTE and in both the journeys, no one came to check tickets. This is alarming as Railways have made it compulsory to fill ID card no at the time of booking of tickets apprehending malpractices. There was no one to allot berths to RAC passengers who were capturing any available vacant berth. Several unauthorized persons were travelling in corridors in this fully reserved train. On the very first trip of its journey, train started late by 1.30 hours from its origin New Delhi.
