I have a Reservation in a Sleeper Compartment in Azad Hind Express from Howrah to Bilaspur. Now, my friend is also booking a Tatkal ticket in the same train on the same date but in AC 3 tier, from Howrah to Nagpur. I just want to ask that is it Ok if I stay with him in the AC Compartment during My part of the journey? Will I be penalised or forced to leave the compartment? Please reply soon.
