New Central Asian Railway Achieves First Major Tunnel Milestone

Bishkek, Tuesday, 8 September 2026.
Engineers completed the first tunnel on a 500-kilometer rail line through Kyrgyzstan, advancing a strategic corridor that bypasses Russia and cuts trade transit times to Europe by eight days.

Construction Milestones and Technical Scope

Construction of the China–Kyrgyzstan–Uzbekistan (CKU) railway has officially commenced, marked by the completion of excavation works at the 209.6-metre-long Kosh Dobo North No. 2 tunnel [1][8]. This achievement represents the first tunnel drilled through on the Kyrgyz section since full-scale work began in June 2025 [2][3]. As of early September 2026, construction activity on the Kyrgyz section includes ongoing work on 27 tunnels, 43 bridges, and 88 railway subgrade sections, with preparations for 20 stations underway [1][5]. The total project scope comprises approximately 29 tunnels and 50 bridges, with multiple tunnels exceeding 5 km in length and the longest exceeding 12 km [1]. The railway will span over 500 km total, with 304.84 km located in Kyrgyzstan, representing 60.968 percent of the total route length [1][2].

Engineering Specifications and Capacity

The line is a single-track design with a maximum speed of 120 km/h, utilizing a dual-gauge system to accommodate regional differences [1][3]. Technical specifications include a gauge change from 1,435 mm, the Chinese standard, to 1,520 mm at Makmal, requiring cargo transfers at the transition point [1][5]. The railway is designed for an annual capacity of up to 15 million tonnes, with initial feasibility estimates projecting 5–8 million tonnes [1]. This target capacity represents a potential increase of 87.5 percent over the lower end of initial feasibility estimates, significantly boosting freight potential [1]. The project is estimated to cost $4.7 billion for the Kyrgyz section, with ownership split 51 percent for China, 24.5 percent for Kyrgyzstan, and 24.5 percent for Uzbekistan [1].

Strategic Trade Implications

The new rail line bypasses northern routes through Russia, significantly shortening freight transit times between East Asia and Southern Europe [1][2]. Potentially reducing transit times to European and Middle Eastern markets by 7–10 days, the corridor offers the shortest land route from China to the Middle East and Europe [1][2]. Some reports indicate transit times could be cut by up to eight days compared to the China-Europe Railway Express, all three main routes of which transit Russia or Kazakhstan [2][3]. This shift marks a substantial change in trans-Eurasian logistics infrastructure, expanding Beijing’s trade influence across Central Asia [1][5]. Russia is concurrently upgrading existing rail crossings and evaluating new highways to manage increasing bilateral trade, indicating awareness of the shifting dynamics [3][5].

Timelines and Future Outlook

Project completion timelines vary, with official Uzbek statements suggesting 2028, while engineering estimates project a date closer to 2031 [1][3]. Chinese President Xi Jinping visited Kyrgyzstan on 2026-08-28 to pledge support for the project’s construction, highlighting its priority status [3][5]. Over 2,000 local workers are employed on the project, with 1,800 trained in construction-related skills, fostering local economic development [1]. While the tunnel milestone confirms active implementation, future operational timelines and specific completion dates for the full railway corridor remain subject to engineering progress [1][5]. The corridor establishes a critical new Eurasian transport axis, transitioning from decades of diplomatic discussion to active implementation [1][2].
