The railway that changes everything
The Transguinean railway: 650 km of mining rail between Simandou and the coast, the Moribaya port (Forécariah), the players (CTG, WCS, Rio Tinto Simfer), the documented cost of the corridor and what the ramp-up changes for Guinea's exports and revenues.

01 Key figures
02 What we know — a 650 km corridor
The Transguinean railway is the 650 km mining line linking the Simandou deposit (south-east) to the port of Moribaya on the Atlantic coast. It was 100% completed in 2025, with about twenty locomotives received by the Compagnie du TransGuinéen (CTG) (MMG N°30; this site's iron ore FAQ).
Key documented steps: reception of the first 4 locomotives and wagons at the port of Moribaya on 29 September 2025 (guineeactuelle.com), under the Simandou 2040 Programme (apanews); first commercial shipment on 11 November 2025; in 2025 Guinea produced 1.53 Mt of iron ore and exported 1.06 Mt (MMG N°30).
03 The port of Moribaya
Located in Forécariah prefecture, the port of Moribaya is where Simandou's iron ore is loaded. WCS and Rio Tinto Simfer both load their production there (this site's iron ore FAQ).
- 29/09/2025: reception of the first trains and wagons at the port (guineeactuelle.com).
- 11/11/2025: first commercial shipment (MMG N°30 / this site's FAQ).
- Early December 2025: a first vessel loaded with 200,000 tonnes leaves Moribaya (tabala.info, 05/12/2025).
- Q1 2026: nearly 1.6 Mt cumulative shipped from Moribaya since the first shipment (SMM, specialist press — to corroborate).
04 The players
- CTG (Compagnie du TransGuinéen): the corridor's infrastructure company (locomotive reception, operations).
- WCS (Winning Consortium Simandou): co-develops the north block and the infrastructure.
- Rio Tinto Simfer: develops the south block.
- Baowu (strategic investor) and Chinalco (reference shareholder) complete the ownership; the Guinean state holds 15% of the mining block (agreement).
- The SMB precedent: the Dapilon-Santou railway (135 km), delivered turnkey in 2021, paved the way for the 'mine + rail' model (Simandou FAQ).
05 What it changes
The railway unlocks Guinean iron ore — the first production year (1.06 Mt exported in 2025) is only the start of a ramp-up towards several tens of millions of tonnes per year (target capacity, MMG N°30).
- Exports: iron ore becomes the country's third export flow, after bauxite and gold. See the exports page →
- Revenues: the FARI model (EITI, June 2025) projects USD 850m/year for the state before 2035 — the basis of the sovereign fund →
- Opening up: the corridor crosses Guinea (Forécariah → south-east) and can carry more than ore.
06 What we know / what we don't know
- We know: 650 km of rail completed in 2025 · ~20 CTG locomotives · first shipment on 11/11/2025 · Moribaya port (Forécariah) · corridor ≈ USD 15bn (horoya.net) · 2025 volumes (1.53 Mt produced, 1.06 Mt exported — MMG N°30).
- We don't know: the exact full-scale capacity per block · the complete ramp-up timeline · financial details of the infrastructure agreements (cost-sharing of rail/port between WCS and SimFer) · consolidated 2026 figures (SMM to corroborate).
