The main system, Sudan Railways, which was operated by the government-owned Sudan Railways Corporation (SRC), provided services to most of the country's production and consumption centers. The other line, the Gezira Light Railway, was owned by the Sudan Gezira Board and served the Gezira Scheme and its Manaqil Extension. Rail dominated commercial transport in the early years but competition from the highways increased rapidly and by 2013, 90% of inland transport in Sudan was by road.[1] The main rail system was reorganised into two companies - the SRC which owned the physical assets of the Sudan Railways and another company which organised the operations with participation of private companies (10 private companies were reported to be running operations in different lines in 2013).[1][2]
