Travelled on KONKAN KANYA 10111 today 16 June 2015 Dadar to Thivim in AC 2 tier coach HA1.. Surprised to see UR passenger sleeping in same berth below me at night. Purchased UR ticket and slept with his friend in 2AC coach( 2 persons in same lower berth) . Also the person sat for most of time in 2 AC coach as well as kept the luggage in 2AC. When the TC came to check, that was the only time he went to UR coach. How can this stopped? It is very unsafe. Still in train.
