Iran Railway Transport: A Practical Guide to Rail Freight Corridors and Transit Routes

Overview of Iran Railway Transport

Iran railway transport is a strategic part of the country’s freight and transit system, linking southern ports, inland industrial centers and international border crossings. Iran’s rail network is reported at around 15,000 km, giving the country a land-based logistics platform between the Persian Gulf, Central Asia, the Caucasus, Turkey, Pakistan and Afghanistan. 

Recent figures also show the growing operational role of rail freight in Iran: according to reports citing the Islamic Republic of Iran Railways, annual freight transport increased from 40 million tons to 44 million tons in the Iranian year 1404, with a target of 54 million tons for the following year. Rail transit is also becoming more important, reaching about five million tons in the year ending March 2025. While road transport still dominates much of Iran’s cargo movement, the Iran railway system is increasingly relevant for bulk commodities, containerized freight and international transit along north–south and east–west corridors.

Why Iran Matters in Regional Rail Transit

Iran matters in regional rail transit because its rail corridors connect several trade zones that are difficult to link efficiently by sea alone. Sarakhs and Incheh Borun provide access to Turkmenistan, Uzbekistan, Kazakhstan and wider CIS markets. Razi–Kapıköy connects Iran with Turkey and onward European routes, while Mirjaveh/Zahedan links Iran to Pakistan and Khaf–Herat supports trade with Afghanistan. In the north, Astara, Caspian ports and INSTC-related links connect Iran with Azerbaijan, Russia and the Caucasus. In the south, Bandar Abbas and Bandar Imam Khomeini serve as maritime gateways where cargo can shift between sea, rail and inland transit corridors.

Main Rail Freight Corridors in Iran

Iran’s rail freight corridors form the backbone of the country’s regional transit role, connecting ports, inland terminals and international borders. They are most valuable where large cargo volumes move over long distances. The main rail freight corridors in Iran can be grouped by destination market and operational function:

Iran–Turkey Rail Corridor
The Iran–Turkey corridor is Iran’s main westbound rail route, running through northwest Iran to the Razi–Kapıköy border. Kapıköy is open to freight and international rail traffic and is directly connected to Iran’s Razi terminal. From eastern Turkey, rail movements depend partly on the Lake Van ferry system, a 90.6 km train-ferry link between Van and Tatvan. This corridor is important for containerized cargo, steel, machinery and industrial goods moving between Iran and Turkey, especially for shippers comparing rail with broader freight transport from Iran to Turkey options. Iran and Turkey have also discussed increasing bilateral rail freight, with a one-million-ton target reported for future annual movement through the rail network.

Iran–Turkmenistan and Central Asia Corridor
Sarakhs and Incheh Borun are among the most important railway gateways in Iran for cargo moving to Turkmenistan, Uzbekistan, Kazakhstan and wider CIS markets. Sarakhs connects Iran’s standard-gauge system with the broader 1,520 mm CIS rail network, making bogie exchange, gauge compatibility and border coordination central to operations. Iran and Turkmenistan have also agreed to develop new standard-gauge and broad-gauge lines at Sarakhs to reduce bottlenecks. Incheh Borun supports the eastern Caspian branch of the Kazakhstan–Turkmenistan–Iran railway, launched in 2014 as part of a north–south route giving Central Asian cargo access to Iranian ports.

INSTC and North–South Corridor
The International North–South Transport Corridor is one of the most strategic frameworks for Iran railway transport. It links India-facing and Persian Gulf trade flows with the Caspian region, Azerbaijan, Russia and Northern Europe through a combination of rail, road and sea transport. In northern Iran, Rasht, Astara and Caspian ports are the key nodes. The main limitation remains the Rasht–Astara railway, a 160 km missing link that Iran and Russia have been working to advance. Once completed, this line would strengthen rail continuity on the western branch of the INSTC and improve Iran rail transit capacity between the Persian Gulf and Eurasian markets.

Iran–Pakistan Rail Corridor
The Iran–Pakistan corridor links southeastern Iran with Pakistan through Zahedan and Mirjaveh, making it relevant for companies assessing shipping cargo from Iran to Pakistan by rail, road or multimodal routes. Its main operational challenge is the break-of-gauge at Zahedan, where Pakistan’s broad-gauge railway meets Iran’s standard-gauge network. This makes transshipment or gauge-management necessary, limiting its use for time-sensitive freight but keeping it relevant for selected containers, project cargo and planned regional transit.

Iran–Afghanistan Rail Corridor
The Khaf–Herat railway is Iran’s key rail connection with Afghanistan. The first three sections, totaling about 140 km, were inaugurated in 2020, with early freight tests including cement movement to Rozanak. This route supports Afghanistan’s access to Iranian ports and regional supply chains, particularly for companies planning freight transport from Iran to Afghanistan. It is suitable for cement, fuel, steel, mining products and essential industrial cargo, although the corridor is still developing operationally.

Iran–Iraq Rail Corridor
The Iran–Iraq rail corridor is centered on the Shalamcheh–Basra project. Unlike Sarakhs or Razi, this is not yet a mature freight corridor, but its long-term value is significant. Iraqi sources describe the Basra–Shalamcheh railway as a 36 km cross-border line and Iraq’s first direct rail connection with Iran. The project has mainly been presented for passenger and pilgrim movement.If developed for freight, it could support construction materials, bulk cargo and future cross-border flows for companies involved in cargo transport from Iran to Iraq.

Major Railway Border Crossings in Iran

Iran’s railway border crossings are where the Iran rail network becomes an international transit system. Each gateway serves a different trade direction, cargo profile and operational requirement:

• Sarakhs — Iran’s main rail gateway to Turkmenistan and the wider CIS region. It is especially important for Central Asian cargo, but gauge and documentation coordination are critical.
• Incheh Borun — Supports access to Turkmenistan, Kazakhstan and the eastern Caspian branch of north–south trade.
• Razi / Kapıköy — Connects Iran with Turkey and onward European rail routes. Kapıköy is open to freight and international traffic and links directly with Iran’s Razi terminal.
• Jolfa / Nakhchivan — Provides a rail connection toward Nakhchivan and remains relevant for Caucasus-related trade flows.
• Astara — A northern gateway linked to the INSTC and Azerbaijan route; its full value depends on stronger continuity with the Rasht–Astara section.
• Mirjaveh / Zahedan — Links Iran to Pakistan, although gauge differences make transshipment planning important.
• Khaf / Herat — Gives Afghanistan access to Iranian ports and regional supply chains, especially for cement, fuel and mining-related cargo.
• Shalamcheh — Iran’s potential rail gateway to Basra and Iraq, with future relevance for construction materials, bulk freight and cross-border trade.

Together, these rail gateways define the practical geography of Iran rail transit for international shippers.

What Cargo Is Suitable for Iran Railway Transport?

Iran railway transport is best suited for cargo that benefits from high capacity, stable routing and lower long-distance transport costs. The most suitable goods include minerals and mining products, cement, coal, grain, fertilizers, steel, construction materials and other bulk commodities that can move efficiently across the Iran freight rail network. Containerized cargo is also appropriate when rail is connected with ports, dry ports or border terminals. In some cases, industrial machinery and project cargo can also move by rail, especially when the route allows safe loading, wagon availability and planned border handling.

However, rail is not ideal for every shipment. Perishable goods without reliable cold-chain support, small parcels, urgent shipments, high-value time-sensitive cargo and goods requiring flexible door-to-door delivery may be better handled by road, air or multimodal solutions. 

Rail vs Road vs Multimodal Transport in Iran

Rail, road and multimodal transport each serve a different role in Iran’s cargo system. Rail is stronger for heavy cargo, bulk commodities, containerized freight and long-distance movement between ports, terminals and borders. It supports cost-efficient Iran rail cargo transport where volume and route stability matter more than door-to-door flexibility. Road transport is better for urgent deliveries, short routes, last-mile distribution and smaller shipments. Multimodal transport becomes the best option when rail cannot complete the full journey alone, combining sea, rail and road under one coordinated logistics plan.

Operational Challenges in Iran Railway Transport

Iran railway transport offers strong advantages for long-distance cargo, but successful rail logistics in Iran depends on careful operational planning. The first challenge is wagon availability, especially for bulk cargo, containers and project shipments during peak demand. Border coordination is another critical issue because customs, railway authorities, terminal operators and freight forwarders must align before cargo reaches the crossing point. On routes linked to CIS countries or Pakistan, gauge compatibility may require bogie exchange, transshipment or additional handling time. Terminal congestion can also affect loading, unloading and multimodal handover at ports, dry ports and inland rail terminals.

Some Iran rail transit routes still depend on incomplete or developing infrastructure, such as the Rasht–Astara section on the INSTC and the Shalamcheh–Basra connection toward Iraq. Seasonal conditions, geopolitical disruptions and changing border procedures may also affect route reliability. For this reason, Iran railway operations require route assessment, document control and contingency planning before cargo is dispatched.

Key Documents for Rail Transit Through Iran

Rail transit through Iran requires accurate documentation before cargo can move across borders, customs points and railway terminals. Requirements vary by cargo type, destination country and corridor, but typical documents may include:

• Commercial invoice
• Packing list
• Certificate of origin
• Rail consignment note
• Transit declaration
• Cargo insurance certificate
• Permits for restricted or special cargo
• Customs clearance documents
• Health or inspection certificates, when required for food, agricultural or regulated goods

For international rail cargo, documentation must match the declared route, HS code, cargo description, wagon or container details and border crossing. Small inconsistencies can delay customs or railway handover. For shipment-specific document planning, SASCO’s rail freight team can review the cargo route, border point and required permits before dispatch.

Recent Developments Affecting Iran Rail Corridors

Recent developments show growing demand for Iran rail corridors as overland alternatives to long maritime routes. In 2025, China–Iran rail traffic gained attention through container movements toward Aprin dry port near Tehran and discussions around a China–Iran–Türkiye–Europe rail route. At the same time, the Rasht–Astara railway remains a key missing link in the INSTC, limiting full rail continuity between Iran, Azerbaijan, Russia and wider Eurasian markets. These projects strengthen Iran’s role in CIS and Central Asian transit, but their impact depends on infrastructure completion, border coordination and reliable multimodal integration.
