Hi Sean. about an hour into your journey you will reach a station where you stop for quite a while for lunch to be loaded on the train which somebody will have been along the train taking orders for. Also there will be wallahs on the platform selling food through the windows, its delicious and costs 10 rupees, From there will be wallahs up and down the train selling food and drink. Dont touch the tea and coffee [5 rupees] unless you can drink it really sweet as that how it comes. The view at the waterfalls is amazing and the passing scenery will keep you entertained and show you the real Indian life.
