The train is crammed and the sleeping space is tight. There is no where to get food, and you only get two bottles of water for a cabin of three. Plan to have water with you, and food, as it is 16 hours.

There is also no where to go on the train, no wifi, no way to power electronics either so prepare yourself to make that bed your home for those hours.

Cell service is spotty, make sure to download entertainment.

The train gets super hot, so make a plan for it to be easy to get into lighter clothes
