Beware of this train, my parents have an reserved seat in 3AC, Compartment B2, i cross checked the seats after chart preparing it was correct. But when i reached station, i was shocked by the negligence by Indian Railways as whole class B2 was replaced by Ordinary Sleeper Class and all passengers of class B2/ 3AC have been accomodated in sleeper class. It was not downgraded but it was fully replaced boggy. No one was there to give my answers, they have only one answer that i you donot want to travel get your ticket cancelled. Very poor service.
