The railway is only partly complete, at present there is a single-track line in Albania and a single-track line in parts of North Macedonia. The route is virtually complete in Bulgaria comprising both single and double track lines. The line already in existence in Albania from
Durrës-Lin will be used, although upgrading and modifications will be needed. From Lin to
Kičevo new construction will be required, almost all in North Macedonia. At the moment progress on this link is small, being mainly aspirational. On North Macedonia's eastern side, the mothballed, 31 km long,
Kumanovo-Beljakovce line has been restored and upgraded – work on this started in 2014. Construction of a new line, approximately 34 km long, from Beljakovce to
Kriva Palanka began in 1996 but was abandoned due to lack of financial resources in 2004. Considerable earthworks and structures are, therefore, already in existence but currently do not reach
Kriva Palanka. Entirely new construction will be needed in the area of
Kriva Palanka to the Bulgarian border (24 km) plus a short length (~1 km) in Bulgaria. A total of approximately 88 km of the track must be restored or built in a region whose morphological features make access difficult. Once in Bulgaria, the existing line from
Gyueshevo, extant since 1910, will be used. From
Gyueshevo the track runs broadly northwards to Sofia then uses the mainline through
Burgas to
Varna. ==References==
