The Iran Rail Corridor: From China and Central Asia to Tehran, Tabriz and Europe
Published: October 1, 2026
The complete Iran corridor: Chongqing and Xi'an to Khorgos, Almaty, Tashkent, Sarakhs, Mashhad, Tehran and Tabriz, then on through Razi and Lake Van to Istanbul and Europe — borders, gauge changes, key terminals, transit times and operational risks.
This corridor is the backbone of our network. Cargo from China or Central Asia enters Iran's rail system at Sarakhs — no Caspian crossing, no sea leg — and is either discharged inside Iran at Mashhad, Tehran or Tabriz, or carried on through Tabriz–Razi towards Türkiye and Europe. The advantage is simple: one border less, one handling less, and therefore less risk for cargo with a hard delivery window.
The route at a glance
| Leg | Points | Technical note |
|---|---|---|
| China | Chongqing, Xi'an, Lanzhou, Ürümqi | 1435 mm standard gauge |
| China–Kazakhstan border | Khorgos / Altynkol, or Alashankou / Dostyk | Gauge change to 1520 mm |
| Kazakhstan and Uzbekistan | Almaty, Taraz, Shymkent, Tashkent, Samarkand, Bukhara | 1520 mm network |
| Turkmenistan | Türkmenabat, Mary | 1520 mm network |
| Turkmenistan–Iran border | Sarakhs | Gauge change back to 1435 mm |
| Iran | Mashhad, Tehran, Tabriz | Clearance at three main inland offices |
| Iran–Türkiye border | Razi / Kapıköy | Gauge change to 1520 mm |
| Türkiye and Europe | Van–Tatvan, Istanbul, Kapıkule, Sofia, Belgrade, Budapest | One multimodal hop across Lake Van |
Borders and gauge changes
- Khorgos and Altynkol: the busiest China–Kazakhstan rail gateway. Bogie exchange or transloading into 1520 mm wagons happens right at the station. In peak season — before Chinese New Year and around the calendar year end — the wagon queue grows, and that has to be priced into the plan.
- Sarakhs: Iran's entry gate. Bogies are changed to standard gauge here and transit documents are checked at the same stop.
- Razi and Kapıköy: the only working rail link between Iran and Türkiye. From here the Van–Tatvan section crosses Lake Van by ferry, with road transfer on part of the stretch; heavy and out-of-gauge project cargo has to account for it from the first draft of the plan.
Key terminals
- Mashhad and Sarakhs — best for discharging in eastern Iran and for transit towards Afghanistan; the customs office closest to the entry border.
- Tehran — the central hub for domestic distribution and for the north–south corridors.
- Tabriz — the north-west gateway towards Türkiye and Europe. For cargo whose final destination is Türkiye or Europe, clearing in Tabriz shortens the door-to-door time.
- Chinese origin terminals — Chongqing, Xi'an and Zhengzhou run the most frequent weekly services towards Khorgos.
Indicative transit times
| Leg | Typical |
|---|---|
| China to Khorgos | 5–7 days |
| Khorgos to Tashkent | 3–5 days |
| Tashkent to Sarakhs | 3–5 days |
| Sarakhs to Tehran | 2–4 days |
| Tehran to Razi | 2–3 days |
| Razi to Istanbul | 4–7 days |
| Istanbul to Central Europe | 3–5 days |
These figures are the working average of scheduled services, not a contractual commitment. Real time depends on border queues, the number of bogie exchanges, customs release and path allocation; a contract states a window, never a fixed day.
What this corridor is good for
- 20 ft and 40 ft containers from China: consumer goods, automotive parts, electricals
- Steel: coils, rebar and profiles in covered wagons or on flat cars
- Petrochemicals and polymers in bags and big bags, subject to dangerous-goods rules
- Project cargo and machinery that need permits and a dedicated securing plan
- Agricultural and food cargo in covered wagons or reefer containers
Risks and operational notes
- Season and capacity: in peak months the bogie-exchange queue at Khorgos and Sarakhs stretches; booking capacity before the season is cheaper than an urgent shipment.
- Different rules at every border: transit paperwork differs by country. One document set covering the whole route prevents avoidable stops.
- The Lake Van stretch: capacity is limited and tied to the ferry schedule; for shipments with hard deadlines an alternative must be assessed in advance.
- Insurance: every extra loading and unloading point changes the cover. The policy has to be issued against the real routing, not the nominal one.
How Lihu runs this corridor
- Wagon and equipment matched to the cargo, from 1520 mm covered wagons to platforms and ISO containers
- One coordinator across three parties: the origin train in China, the Central Asian operators and the Iranian rail network
- Clearance at Sarakhs, Mashhad, Tehran or Tabriz, whichever the contract provides for
- Status reporting from control points — bogie exchange, border crossing, arrival in Iran — instead of vague updates
Field note: on this corridor most delay happens at the Khorgos border and in customs release, not on the rail line. Precise documentation saves more time than a faster train.
