Sudan Railways is the main railway system in Sudan, operated by the government-owned Sudan Railways Corporation. It runs over 5000km of narrow gauge, single-track railroads that serve the northern and central parts of the country. The main line underwent construction in 1875, completed in 1899, and runs from Wadi Halfa to Khartoum, and southwest to Al Ubayyid via Sannar and Kosti. In 1904-5 a line between Swakin and Atbara was constructed with the two lines meeting at Saloom station, to facilitate export and import transportation. In 1906 the railway headquarters and workshops were moved from Wadi Halfa to Atbara, and since 1981 the company headquarters have been based in Khartoum. In the 1980’s Sudan Railways declined due to political instability and debt, with lines operating at only 20% capacity by 1989.

In 2011-2012 a contract was signed to build a line from Nyala to Chad, extending to the capital of Chad, N’Djamena. In 2015 Sudan Railways had 60 trains available but which could only travel at 40km per hour due to poor track conditions, with President Omer Hassan al-Bashir promising modernisation of the Sudanese railways with Chinese funding.
