Çerkezköy–Kapıkule high-speed line opens while the Istanbul link is unfinished
President Erdoğan on 9 October opened the 153-kilometre Çerkezköy–Kapıkule section of the Halkalı–Kapıkule line at a ceremony attended by EU Enlargement Commissioner Marta Kos. Annual freight capacity is set to rise from 1.5 million to 9.5 million tonnes, but two sections at the Istanbul end are not yet finished.
Anadolu Agency reported on 9 October that the 229-kilometre Halkalı–Kapıkule line is being built in three phases, and the section now open is the longest. The double-track, electrified and signalled line was built for 200 kilometres an hour. Passenger journeys are expected to fall from 4 hours to 1.5 hours, and freight transit from 8.5 hours to 3.5 hours. Annual passenger capacity will rise from 600,000 to 3 million.
The constraint lies at the Istanbul end. Dünya reported on 4 October that the Ispartakule–Çerkezköy section and the link from Ispartakule to Halkalı are still under construction. Takvim reported on 9 October that the Halkalı–Çerkezköy phase, including the roughly 69-kilometre Ispartakule–Çerkezköy section, is due for completion in 2028. The 1.5-hour journey and the 9.5 million tonne capacity depend on the whole line being finished. According to Dünya, 86% of export freight moved by rail in 2024 passed through this corridor. About 2.4 kilometres between Kapıkule and the Bulgarian border will be converted to double track.
Erdoğan described the line as an artery linking Anatolian production to European markets. Anadolu Agency said it connects to the Middle Corridor via Baku–Tbilisi–Kars and Marmaray, and to the 6,314-kilometre Development Road, 2,094 kilometres of which run through Türkiye. Neither the project's cost nor any EU financing was disclosed. The number of tracks at Kapıkule station rises from 23 to 42, but the sources disagree on total track length, with Anadolu Agency giving 51,000 metres and Dünya 29,680 metres.
Talay assessment
Bottom line
The opening gives substance to Türkiye's promise to raise capacity on its overland freight route to Europe more than sixfold, but the full promise rests on the two sections at the Istanbul end. Until they are finished, freight runs on old infrastructure as far as Çerkezköy and the 3.5-hour transit time will not materialise. The EU Enlargement Commissioner's attendance is a political signal; no concrete commitment on financing or customs was announced.
Likely effects
- Export logisticsPositive1–6 months
More capacity on the corridor carrying 86% of rail export freight offers an alternative to lorry queues on overland routes to Europe; the full effect depends on completing the Halkalı link.
- Kapıkule border crossingUncertain1–6 months
Raising station tracks from 23 to 42 eases the bottleneck on the Turkish side; the 2.4-kilometre single-track stretch on the Bulgarian side could become the new one.
- Middle CorridorPositive6 months+
Via Kars and Marmaray, the line completes the European end of the Asian link, improving the competitiveness of the Turkish route for Asia–Europe transit freight.
Possibilities, ranked
- 1Phased rollout55%
Freight trains use the new section, but capacity gains stay limited until the Istanbul end is finished; full capacity remains tied to the 2028 target.
Watch: The completion date the Transport Ministry gives for the Ispartakule–Çerkezköy section
- 2Rapid completion25%
The Istanbul-end sections finish ahead of the 2028 target, freight transit falls to 3.5 hours and rail's share rises markedly.
Watch: TCDD monthly freight tonnage data via Kapıkule
- 3New bottleneck at the border20%
Extra capacity on the Turkish side runs into track and customs limits on the Bulgarian side, and the gains evaporate at the border.
