Pehlivanköy - Turkey Svilengrad railway line with one of the two railway lines connecting Europe, is an important freight corridor.
The railway line was built by the Chemins de fer Orientaux / Rumeli Railway (CO) Company as part of the line of the Rumeli Railway between 1870 and 1873. The construction of the Rumeli Railway, which was started to be built entirely within the territory of the Ottoman Empire in 1870, was frequently interrupted due to the riots in the Balkans and the 93 War. When the line was put into service in 1888, it was now in Bulgaria, Serbia and the Ottoman territories. After the Balkan Wars and World War I, a part of the line remained within the borders of Greece. With the borders determined by the last War of Independence, the part of the railway line between Pythio (Kuleliburgaz) and Karaağaç remained within Greek territory. In this case, since 1923 - between 1971 and Turkey he was forced to move from their land in the neighborhood of Edirne Elm Elm Train Station and the border with Bulgaria and Greece to reach the railways. With the Pehlivanköy - Svilengrad railway line built by TCDD and BDZ in 1971, a direct connection to Edirne and Bulgaria was provided without having to cross the borders of Greece. With the construction of this line, the railway line in Karaağaç was closed for use. However, the original Rumeli Railway line in Pythio is still used by OSE as a rail link to Bulgaria.
Today, on the railway line by TCDD Tasimacilik, Istanbul-Halkalı - Kapıkule and Istanbul-Halkalı - Uzunköprü Regional Trains are operated.
