I was shocked but perhaps it was natural for the TTE. I boarded Azad Hind Express at Jharsuguda for Kolkata on 23 January 2008. My ticked in AC 2 Tier was confirmed. There were three other people. TTE came and checked my ticket. The three people gave their second class sleeper tickets for reserving birth in AC 2 tier. I could gather that they had been permitted by TTE to board the train.
