Overnight trains have traditional sleeping cars with bedrooms ranging from single 'roomettes' to family size affairs. Accommodation includes breakfast, lunch and dinner in the dining car, as well as complimentary coffee, fruit juice and a newspaper delivered each morning. Meals are above airline standard but the chicken and steak menu may become monotonous after a while. Luckily, there is often a regional special such as freshly-caught trout or barbecued spare ribs. Ticket prices are amazingly low and overseas visitors benefit from an array of passes which are among the world's great travel bargains.
Trains are glamorous, ecologically sound and far more fun than the bus.
Since they will take you almost everywhere, it's easy to work out an itinerary which lets you see more of this diverse country in a short time than would be possible any other way. In fact, some places can not easily be visited by any other means.
