Don't forget to buy food and drinks in advance if you need them: train stations do not always have shops, while onboard cafés are not always available and often very expensive.
If the train timetable doesn't fit in your schedule or budget, bus and carpooling can provide you some time and price alternatives, without substantially changing the duration of the journey.
