I am travelling from sbc to nzm on 1 Feb with a female friend. I have booked our tickets in sleeper as the friend hasnt travelled in train much. I wish to know how the crowd, hygiene and safety would be. 3ac is still available. But I believe that sleeper class is the real way to enjoy journey . as I usually end up standing at the gate even if travelling by 3ac. Please advise me.
PS- we both usually take flight for this distance
