At Hat Yai Junction, when I take the train to Malaysia, I have to cross two railway tracks to the last track to board the train. If I don't do that, I will have to carry my luggage, go into the tunnel and come up again - without escalator.
Maybe he needs hearing aids or he lost his hearing aid domes and can't wear aids anymore.
The reasons can be very different, still hope that the guy is alright.
The situation like that can occur, even these days in our society.
