this is what happens when you have seats with attached toilets in a train ( berths 1-8 and 72-80 are seats with attached toilet for me)
12801 Purushottam SF Express develops a very pungent stink after 12 hours journey,and the bad odor quickly fills the adjacent bay everytime the train starts/stops, and you really need additional breathing support to be in the bay area 1-8 or 72-80
clicked one such passenger who seems to be overwhelmed by the the unpleasant odor
