Kazakhstan Middle Corridor Railway Cuts Detour, but Caspian Bottlenecks Remain

Kazakhstan expects to complete the roughly 323-kilometer Moyynty-Kyzylzhar railway across the Karaganda and Ulytau regions of central Kazakhstan by the end of 2026. The new line will shorten the Middle Corridor by 149 kilometers and ease congestion on the existing route via Zharyk. Kazakhstan Temir Zholy said in July that 202.5 kilometers of track had been laid. For the China-Europe route, however, the next test is the Caspian Sea. Containers must be transferred from trains at ports in Kazakhstan to ships bound for Azerbaijan, then returned to rail. The speed and regularity of these transfers will determine whether the hours saved within Kazakhstan translate into shorter delivery times. What the New Line Changes Moyynty-Kyzylzhar will give transit trains a more direct route from the Chinese border toward the Caspian and ease pressure on the Moyynty-Zharyk section, where east-west freight competes with domestic traffic. The project is designed to accommodate double-stack container trains and includes provisions for future expansion and electrification. The World Bank projects that capacity on the section will rise from 14 to 28 pairs of freight trains per day, while transit time via the new route is targeted to fall from eight hours to six by 2031. In February, the World Bank approved an $846 million guarantee intended to mobilize $1.41 billion in commercial financing for the project. Across Kazakhstan, the time savings will be more modest. Transit from Dostyk, on the Chinese border, to Aktau is expected to fall from about 72 hours to 68 hours by 2031. Farther west, the country is also modernizing the Shalkar-Beineu and Beineu-Mangystau sections leading toward the Caspian ports. The Caspian Remains a Bottleneck The European Union (EU) aims to reduce transit time along the Trans-Caspian route to no more than 15 days. The European Bank for Reconstruction and Development (EBRD) has estimated that the route has the potential to move cargo between China and Europe in around 18 days, but infrastructure and connectivity constraints have produced transit times ranging from 14 to 60 days. For shippers, reliability is as important as speed. Freight Is Growing Faster Than Caspian Capacity Pressure on the Caspian section is already increasing. In 2025, Kazmortransflot carried 59,400 twenty-foot equivalent units (TEU) on the Aktau-Baku-Aktau feeder route, more than 15% above the 2024 level of 51,400 TEU. In May 2026, container traffic between Aktau and Azerbaijan reached a company record of 7,451 TEU. Kazakhstan is expanding its port infrastructure as well. The EBRD and the EU are financing upgrades at Aktau, including two dedicated container berths and new handling equipment. The project is expected to double the port’s container-handling capacity. Caspian fleet capacity is another constraint as rail freight grows. Falling Caspian Sea levels are also limiting how fully some vessels can be loaded. From an Alternative to Russia to a Commercial Route After 2022, geopolitics increased demand for the Middle Corridor. It offered Europe a route to Central Asia and China that bypasses Russia, while providing Kazakhstan with another connection to European markets. The corridor increasingly has to compete on commercial terms....

Landlocked Kazakhstan Builds a Logistics Network from China to the Black Sea

Although Kazakhstan is landlocked, companies based in the country already hold stakes in logistics terminals at Lianyungang on China’s Yellow Sea coast and in Poti on the Black Sea. Projects farther west are at various stages of development. The strategy allows Kazakhstan-based operators to remain involved as freight travels between Asian ports and European markets, including beyond Kazakhstan’s borders. One of the main facilities is at the Chinese port of Lianyungang. The China-Kazakhstan Logistics Cooperation Base began operating in May 2014. It was jointly developed by Lianyungang Port and Kazakhstan Temir Zholy (KTZ), Kazakhstan’s national railway operator. Cargo arriving by sea can be transferred to rail for shipment through Kazakhstan toward Central Asia and Europe. In a written response to The Times of Central Asia, Kazakhstan’s Ministry of Transport said the Lianyungang terminal handled 2.39 million twenty-foot equivalent units (TEU) from 2015 through 2025. Annual throughput rose from 167,000 TEU in 2015 to 271,700 TEU in 2025. A further 140,100 TEU passed through the terminal during the first half of 2026, down 3.2% year on year. According to Samruk-Kazyna, the network extends inland to a terminal in Xi’an and includes Khorgos Gateway at the Kazakhstan-China border. The fund said a dry port in Chengdu would be added in 2027. At the western end, Kazakhstan-based PTC Holding and Georgian partners developed a multimodal terminal that opened in Poti in June 2025 after investment of more than $30 million. The operator currently lists annual throughput capacity at up to 100,000 TEU. Between the terminals in China and Georgia lies Kazakhstan’s rail network, which carries cargo to the Caspian ports of Aktau and Kuryk. These links form Kazakhstan’s section of the Trans-Caspian International Transport Route, known as the Middle Corridor. The route connects China with Europe across the Caspian Sea and the South Caucasus. Kazakhstan is pursuing further terminal projects along the route. In July 2026, Kazakhstan and Azerbaijan were preparing to begin construction of a joint intermodal terminal at Alat. Work was awaiting completion of the Port of Baku’s updated master plan. In June 2026, Kazakhstan’s government said work would begin on terminals in Budapest and Constanța. Later that month, KTZ Express signed an agreement with Midia Marine Terminal for a joint project at Romania’s Port of Midia. The European projects have yet to reach the operating stage. The value of this terminal network becomes clearer from the way the Middle Corridor operates. Containers must move between rail and ships for the Caspian crossing, so faster transit across Kazakhstan cannot determine the total journey time. The World Bank has identified the Caspian and Black Sea crossings as bottlenecks requiring greater vessel availability and higher port productivity. Transit times vary by destination. Turkish officials reported in August 2025 that a freight train from China had reached Turkey in 15 days, while earlier journeys often took more than 20 days because of customs procedures and weather on the Caspian Sea. A 15-day journey should therefore be treated as a benchmark rather than a guaranteed...
