Haha, lol. I've done those multiple day train rides in India. They actually have showers, you know!? You have to take along your own bucket and cup for pouring water over yourself. You'd think you wouldn't want to go there, but after being on a day for a few days, freshening up like that really does make you feel way more clean. Just a small tip for if another birdy comes along with a new great destination and you'd need a trainride to get there ;). Enjoy your travels!!
