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.

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

LegTypical
China to Khorgos5–7 days

Tashkent to Sarakhs3–5 days
Sarakhs to Tehran2–4 days
Tehran to Razi2–3 days
Razi to Istanbul4–7 days
Istanbul to Central Europe3–5 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.
