Children under three travel free. Children aged three to seven pay half fare. An extensive rail network runs throughout Java. There are three classes of travel, but first-class exists only on principal expresses. There is some air-conditioned accommodation.

Nearly half of the network is paved. There are good road communications within Java and to a lesser extent on Bali and Sumatra. The other islands have poor road systems, although conditions are improving with tourism becoming more important. Road tolls are in operation on some major city roads and need to be paid for by visitors if using a taxi. Chauffeur-driven cars are widely available, with rates varying according to the type of destination.
