Iran’s Secret Railway Route to China Can It Bypass Hormuz?

Iran is expanding railway trade with China through Central Asia. Could land routes help Tehran bypass the Strait of Hormuz and transport oil?

TEHRAN / XI’AN | November 2, 2026

As maritime trade routes face disruption and economic pressure on Iran continues, Tehran is increasingly looking towards railway and road connections through Central Asia to maintain commercial links with China.

A freight railway corridor connecting China's city of Xi'an with Iran's capital, Tehran, has gained importance as an alternative route for transporting goods without depending on shipping through the Strait of Hormuz.

The increase in freight movements and recent statements by Iranian officials have also raised a bigger question: Could Iran eventually use these land routes to transport crude oil to international markets if maritime exports become difficult?

The railway offers an alternative for trade, but its ability to replace large-scale oil shipments remains limited.

China–Iran railway corridor gains importance

The direct freight railway service between Xi'an and Tehran was launched in May 2025. The route travels through Central Asian countries, including Kazakhstan and Turkmenistan, connecting Chinese markets with Iran's railway network.

Following maritime disruptions in 2026, freight train movements reportedly increased significantly.

According to a Bloomberg report published on May 8, 2026, the number of freight trains travelling from Xi'an to Tehran rose from approximately one train per week before the blockade to one every three or four days afterwards.

The corridor is intended to provide an alternative for transporting industrial products, machinery, consumer goods and other commercial cargo.

However, the actual journey can take considerably longer than advertised schedules because of border inspections, customs procedures, railway connections and other logistical challenges.

Iran claims land routes could carry up to 400,000 barrels of oil daily

An important development came on September 29, 2026, when Iranian parliament presidium member Meisam Zohourian stated that Iran could potentially transport between 300,000 and 400,000 barrels of crude oil per day through combined railway and road networks.

According to reports of his remarks, activating additional land routes could help Iran develop non-maritime export channels and potentially support future pipeline projects.

The statement describes a proposed or potential transport capacity. It does not establish that Iran is currently exporting 300,000–400,000 barrels of crude oil every day through these routes.

Zohourian also acknowledged that much of the existing railway freight movement is one-directional, with goods arriving from China and some trains returning with empty wagons. Expanding exports through the railway network could help address this imbalance.

Why railways cannot replace oil tankers

Despite the strategic importance of the corridor, transporting crude oil by rail is fundamentally different from moving it through large oil tankers.

A railway shipment requires specialised tank wagons, loading facilities, border coordination, storage infrastructure and unloading arrangements. Moving hundreds of thousands of barrels every day would require a substantial and continuous supply of railway equipment.

By comparison, a large crude-oil tanker can carry hundreds of thousands or even millions of barrels in a single voyage.

An analysis published by The Diplomat in May 2026 highlighted several limitations, including the geographical distance between Iran's southern oil-producing regions and the railway routes leading through Central Asia. It also noted that China's major coastal refineries are better positioned to receive seaborne crude than oil delivered overland to western China.

The Strait of Hormuz remains strategically important

According to the International Energy Agency, approximately 20 million barrels of oil per day passed through the strait in 2025, representing around one-quarter of global seaborne oil trade.

Iran's dependence on maritime routes makes alternative transport infrastructure strategically important, particularly during periods of conflict, sanctions or shipping disruption.

However, railway and road corridors cannot currently offer the same volume or cost efficiency as maritime transportation.

Iran's growing reliance on land-based trade routes is also attracting attention from Washington.

In October 2026, the United States imposed sanctions on several Iranian railway companies as part of its wider pressure campaign against Tehran.

A report by Deutsche Welle on October 21 highlighted how sanctions, insurance restrictions, payment difficulties and customs delays could complicate the expansion of Iran's railway trade with China and Central Asia.

These challenges mean that building railway infrastructure alone will not guarantee uninterrupted international trade.

An emergency alternative, not a replacement

Iran's railway connection with China represents an important development in regional trade and transport infrastructure. It gives Tehran another way to receive goods and explore alternative export channels when maritime routes face disruption.

But the distinction is important: the reported increase in freight trains primarily concerns commercial cargo, while the proposed 300,000–400,000 barrels-per-day oil transport figure is an Iranian official's estimate of potential combined road and rail capacity.

For now, the corridor is better understood as a potential emergency trade lifeline than a complete substitute for oil tankers and maritime exports.

Whether Iran can turn this railway connection into a commercially viable large-scale crude oil export route will depend on infrastructure investment, international cooperation, sanctions and the economics of overland transportation.
