South Sudan has 248 km of single-track 3 ft 6 in gauge railway line from the Sudanese border to Wau terminus. There are proposed extensions from Wau to Juba. There are also plans to link Juba with the Kenyan and Ugandan railway networks.
The busiest and most developed airport in South Sudan is Juba Airport, which has regular international connections to Asmara, Entebbe, Nairobi, Cairo, Addis Ababa, and Khartoum. Juba Airport was also the home base of Feeder Airlines Company and Southern Star Airlines.
Other international airports include Malakal, with international flights to Addis Ababa and Khartoum; Wau, with weekly service to Khartoum; and Rumbek, also with weekly flights to Khartoum. Southern Sudan Airlines also serves Nimule and Akobo, which have unpaved runways. Several smaller airports exist throughout South Sudan, the majority consisting of little more than dirt runways.
On 4 April 2012, plans were unveiled to launch a South Sudanese national airline, primarily for domestic service at first but eventually expanding to international service.
