The Edirne cut-off is a 80 km (50 mi) long rail line from Pehlivanköy, Turkey to Svilengrad, Bulgaria. The line was built in 1971 by the Turkish State Railways in order to avoid crossing the border with Greece, on the former Oriental Railway's main line, in order to get to Edirne. The Hellenic Railways Organisation (OSE) also built a cut-off from Neo Vyssa to Marasia in the same year. These two new rail lines led to the abandonment of the former CO main line in Edirne as well as the Karaağaç Railway Station.
