Beta, for 500 km, do not go in that crowded sleeper or even 3-tier. Take the flight. At my age, the heat and the jostling on trains make my old bones ache. I see the crowds at the station and I remember how hard it is to even walk in the market during summer. For a peaceful journey, spend a little extra from your savings, just like I am carefully spending for my daughter's wedding—some comforts are worth it.
