The above ground railway system, although just as efficient as the subway, takes a bit more getting used to because each line is owned by different companies and this dictates the safety and cleanliness of the ride.

Almost all the suburbs are accessible through the train system and more information can be found in city maps/guides in roadside shops and on the transport company websites:
