Pros: Spacious leg room and cool air condition. Cons: The section where I stayed was oozing with foul smell and I had to use my air freshener and perfume to make the areas around me breathable. Also since the trip on the train is usually a long one, free Wi-Fi should be available (not only on the bus!) as mobile internet fluctuates depending on how remote the area or strong the signal strength is. Rest room gets messed up pretty fast, sanitary conditions should be adequately taken care of. Tips: Do not litter the area where you seat with your food or trash, and be considerate of the person sitting next to you.
