On September 21, 2026, Wabtec, a US railway equipment manufacturer, signed a multi-year service agreement worth over $700 million with CTG, a cross Guinea company, to provide long-term support for the Evolution series locomotives of the Simandou Railway. This is Wabtec's largest service contract in Africa, covering planned maintenance, temporary repairs, component refurbishment, spare parts management, logistics support, personnel training, remote diagnostics, and localized construction. Wabtec has previously secured two orders, primarily for locomotives, from SimFer and Win Alliance Ximendu WCS, with a total publicly disclosed amount of $525 million. The amount of the newly signed service contract is at least $175 million higher than the sum of these two orders. The procurement focus of the Simandou Railway has shifted from purchasing locomotives to maintaining long-term locomotive availability.

Service contracts are larger than equipment orders

In July 2024, SimFer announced a $277 million Wabtec locomotive order, with a later disclosed purchase quantity of 78 units. In January 2025, WCS announced another $248 million order for locomotives and services, with the number disclosed by the Guinea Presidential Office being 65 units. The two batches of publicly available quantities add up to a total of 143 units, all of which serve the Trans Guinea Railway. The long-term service agreement signed by CTG this time exceeds $700 million, and with previous orders, Wabtec's total locomotive and service contracts in Simandou have exceeded $1.2 billion. The amount of the service contract is more than the total amount of the equipment procurement contract, which indicates that continuous maintenance, spare parts, and technical support are themselves a larger long-term business. This amount is the total amount of years of service, and annual payments and fee changes are still executed according to the terms of the contract.

Maintenance spare parts and data are included in the same contract

This contract covers the main stages after the locomotive is put into operation. Planned maintenance is responsible for periodic maintenance and temporary repairs to handle sudden malfunctions; Component refurbishment and spare parts management determine the waiting time for faulty locomotives to receive parts; Logistics support delivers spare parts, tools, and personnel to the required locations; Training and localization construction should leave some of the capabilities in Guinea. Remote diagnosis allows Wabtec to continue accessing locomotive operation data for identifying faults and arranging repairs. For CTG, the goal is to improve locomotive availability, efficiency, and reliability. For other suppliers, core locomotive after-sales, specialized components, and diagnostic systems have been included in Wabtec's overall service scope, and the space to directly replace the original factory solution has become smaller. Enterprises with supporting capabilities are more likely to enter through Wabtec approved supply chains or local services purchased separately later.

CTG operates railways in two major mining areas in a unified manner

The Ximangdu mine is divided into two groups of development entities. WCS is responsible for Blocks 1 and 2, while SimFer is responsible for Blocks 3 and 4. Both sides will purchase locomotives separately, and the railway and port will ultimately be jointly owned and operated by CTG. According to the CTG official website, the government of Guinea holds a 15% stake, with SimFer Infraco and WCS Infraco each holding 42.5%. The cross Guinea railway spans over 600 kilometers, connecting the southeastern mining area to the port of Morebaya, and is also planned to undertake passenger and non mineral product transportation. The two mining areas share a transportation corridor, and locomotive malfunctions, spare parts shortages, and maintenance waiting can all affect how much capacity the railway can allocate. The signing of a long-term service agreement directly by CTG this time means that the locomotive procurement, which originally belonged to two groups of mining shareholders, is entering the stage of unified operation and unified support. For Chinese suppliers preparing to follow up, the first thing to distinguish is the purchasing entity, technical authorization, and localization conditions, and then check whether the CTG procurement page and Wabtec execution team have released specific work packages.Editor/Gao Xue
