Rail Freight from Iran to Central Asia: 2026 Route Guide
Rail freight from Iran to Central Asia explained: Sarakhs and Incheh Borun gateways, the Gorgan–Bereket–Uzen line, gauge change and documents.
Rail freight from Iran to Central Asia mostly crosses into Turkmenistan at Sarakhs in the northeast or at Incheh Borun in the north. Iran's network uses 1,435 mm standard gauge. Turkmenistan and Kazakhstan use 1,520 mm. So every wagon meets a break of gauge at the border.
Buyers and agents often ask whether rail freight from Iran to Central Asia beats trucks. For heavy, non-urgent cargo it can, if the border step is planned well. This guide covers the gateways, the line through Bereket and Uzen, the gauge change and the paperwork. Royan Logistic is a Tehran-based company that arranges rail, road, sea and air freight, plus customs coordination.
The two main gateways for rail freight from Iran to Central Asia
Two Iranian rail gateways lead into Turkmenistan. Each feeds a different part of the Turkmen network.
| Gateway | Iranian side | Turkmen side | Role |
|---|---|---|---|
| Sarakhs | Mashhad–Sarakhs line | Sarakhs, linked to Tejen | Eastern gateway, part of the North–South corridor |
| Incheh Borun | Gorgan | Etrek, then Bereket | Northern gateway toward Kazakhstan |
Your forwarder will tell you which gateway suits your wagon type, cargo and destination station.
Congestion can change that choice. In August 2025, Iran and Turkmenistan discussed two new lines between the Sarakhs stations, one standard gauge and one broad gauge. The aim was to ease freight backlogs. Check the current status before you book.
Gorgan–Incheh Borun–Bereket–Uzen: the Kazakhstan–Turkmenistan–Iran line
This line is the eastern branch of the International North–South Transport Corridor. It starts at Gorgan in Iran's Golestan province. It reaches the border at Incheh Borun, passes Etrek and Bereket in Turkmenistan, and ends at Uzen in Kazakhstan.
Published lengths differ by source, from about 680 km to about 925 km, depending on what is counted. The Turkmen section is by far the longest. The Iranian section from Gorgan to Incheh Borun is about 80 km. Treat all figures as approximate.
The Iranian section from Gorgan to Incheh Borun was ceremonially opened in May 2013. The full link between the three countries opened in December 2014. Bereket is the key junction, where the line meets the Trans-Caspian railway. In Iran, the line connects to the national network that serves ports on the Persian Gulf.
For a shipper, this line makes rail freight from Iran to Central Asia a continuous path between Kazakhstan, Turkmenistan and Iran. It suits bulk and heavy cargo best. For a wider route comparison, read our guide to Iran to Central Asia freight routes.
How the break of gauge works at the border
A wagon built for 1,435 mm track cannot roll onto 1,520 mm track. Something has to change at the border. There are three usual methods.
- Bogie exchange: the wagon is lifted and its wheel sets are swapped. Bogie exchange is reported at Sarakhs.
- Transshipment: cargo moves from one wagon to another. This is used for mixed loads or when suitable wagons are not available.
- Container transfer: containers are lifted from one platform wagon to another.
Railway Gazette reported in 2013 that bogie-changing facilities at Incheh Borun were still to be provided. Facilities have changed since then. Ask for the current arrangement.
Each handling step adds time and a small risk of damage. Pack cargo to survive lifting and shunting. Our China–Iran rail corridor article shows how the same gauge issue affects trains from the east.
Which cargo suits rail freight from Iran to Central Asia?
Rail works best for steady, heavy and non-urgent flows. Typical matches include:
- Bulk goods such as grain, fertilizer and minerals.
- Containers of 20 ft and 40 ft on platform wagons.
- Palletized industrial goods in covered wagons.
- Liquids and chemicals in tank wagons, under rail dangerous-goods rules.
Rail is a weaker fit for small urgent parcels or for sites far from a rail spur. In those cases, combine rail with trucks. Our intermodal transport service covers this mix, and our rail freight page lists the basics.
Wagon supply, loading slots and border queues change with the season and demand. Ask for a schedule that matches your cargo, not a generic promise.
Rail or road: how to decide
Rail freight from Iran to Central Asia pays off when volumes are steady and the cargo is heavy. One train replaces many trucks. Fewer vehicles also means fewer permits and fewer driver changes.
Road has its own strengths:
- Door-to-door delivery without a rail spur.
- Flexible departures for small and urgent loads.
- No gauge change, although there are border queues and transit permits.
Many shippers mix both. A truck collects the cargo at the factory, a train covers the long middle, and another truck delivers the last kilometres. Ask for both quotes, then compare handling points, not only the headline rate. Our guide to full truckload (FTL) shows the road side of that comparison.
Documents and planning checklist
Prepare these items before booking space:
- Commercial invoice and packing list.
- Rail consignment note. The SMGS note is widely used in the former Soviet area. Your carrier confirms which one applies.
- Customs declarations in each country on the route.
- Certificates, such as origin or phytosanitary, if the cargo needs them.
- Cargo insurance for the full rail leg and handling points.
Rules, tariffs and quotas change. Confirm current requirements with Iran Customs (IRICA) and the carrier. Also confirm current trade, banking and insurance restrictions with your bank or legal adviser.
Loading quality matters more on rail than many shippers expect. Block and brace the cargo, keep it dry and use sound pallets. A wagon may be shunted several times, and a gauge change adds one more lift. Poor packing is the most common avoidable cause of damage claims on rail freight from Iran to Central Asia.
Frequently asked questions
Is there a direct train from Iran to Kazakhstan?
There is a continuous rail connection through Turkmenistan. It is not a single-gauge through run. The gauge changes at the Iran–Turkmenistan border.
Which is better, Sarakhs or Incheh Borun?
It depends on your origin station, destination and wagon type. Sarakhs is in the east. Incheh Borun leads toward Bereket and Kazakhstan. Border congestion can also decide.
How long does rail transit take?
Rail freight from Iran to Central Asia has no single transit time. It depends on the origin station, wagon availability, border handling and the final destination. Ask your forwarder for a route-specific estimate.
Can I ship a single container by rail?
Often yes, but availability varies. Space on container trains and consolidation options change by season. For smaller loads, compare with freight from Iran to Kazakhstan by road.
