[1][2] The main railway would run 146 km from Lothair in Mpumalanga in South Africa to Sidvokodvo Junction in Eswatini.
[4] There are also plans for 600 km of connecting railways, and this route fits with several other Transnet infrastructure projects which concentrate on coal transport.
[5] This would also allow further development of the railway which takes coal from the Waterberg Coalfield via Ermelo to Richards Bay; the Waterberg coalfields have South Africa's biggest undeveloped coal reserves.
[6] The project officially began in January 2012 and was initially expected to cost between R15bn and R17bn, with the South African government paying up to R12bn.
[4] In July 2014, Swazi Railways estimated that the link would cost R17 billion and could enter service in 2017.
