Greenbrier Maxion

What Greenbrier Maxion does

GBMX (formerly Greenbrier Maxion) is the largest railway freight car and bogie manufacturer in South America, headquartered in Hortolândia, São Paulo, Brazil, with approximately 1,000 employees operating from a 951,400 m² industrial complex. The company was formed in 2017 as a joint venture majority-owned (60%) by The Greenbrier Companies (NYSE: GBX), alongside Amsted Rail Inc. and Brazilian industrial group Iochpe-Maxion, and traces its lineage to Fábrica Nacional de Vagões (FNV), founded in 1943. GBMX produces over 50% of the Brazilian railcar fleet in operation across 30+ models in five categories (Hopper, Gondola, Plataforma, Tanque, Fechado) and four bogie product lines (Motion Control®, Swing Motion, Ride Control, Super Service Ride Control) developed in partnership with Amsted Rail. Proprietary technology includes the Motion Control® bogie with Adapter Plus controlled-stiffness adapters, patented low-alloy steel for jaw components, microligated steel wheels, and a cast front end replacing sheet metal. The company's products are engineered for Brazilian gauge and operational conditions and target measurable efficiency outcomes such as 151,000-liter annual diesel reduction on the HTT hopper and 40% cargo capacity optimization on the double-stack platform.

The company complements hardware sales with a full lifecycle services portfolio — Reform (reform/reconditioning), Revision and Maintenance, Integrated Maintenance (turnkey), Transformation (modification/repowering), Consulting, and Components (CKD kits, recovery, exchange parts) — delivered from a 4,000 m² dedicated service facility. Customers include Brazilian railway concessionaires and operators, and end-users in agriculture (grains, fertilizers), mining (iron ore, bauxite, coal), pulp and paper (cellulose), and petroleum and chemical (liquids, cement, sulfuric acid). The business operates ISO 9001, ISO 14001, and ISO 45001:2018 certified management systems and has held the Selo Verde environmental certification since 2017.

GBMX operates a private B2B direct-sales model selling custom-manufactured railcars, bogies, components, and services through quote-based multi-year contracts to enterprise customers. Distribution is domestic-focused, supported by a corporate website contact system with dedicated departments for Sales, Engineering, Purchasing, and After-sales. While core revenue is generated in Brazil, the related AmstedMaxion foundry in Cruzeiro (51% Amsted Rail) supplies railway castings globally to South America, Africa, Asia, and the United States, providing indirect international reach for the broader joint-venture ecosystem. In January 2026, the company rebranded from Greenbrier Maxion to GBMX with the slogan 'Movendo o que é importante' (Moving what matters), signaling a repositioning around innovation and sustainability.

Broad incumbents

• Alstom: Euronext-listed (ALO) French global rail OEM producing locomotives, passenger trains, and rail services. Stronger focus on passenger rail and signaling, but a broad incumbent with overlapping freight and rail-services exposure.
• Wabtec Corporation: NYSE-listed (WAB) global rail equipment and services provider offering locomotives, freight car components, brakes, and digital solutions. Broad incumbent with overlapping capabilities in bogie/wheel components and rail services, but portfolio-wide rather than railcar-focused.
• CRRC Corporation: Hong Kong/ Shanghai-listed state-owned global rail equipment giant producing locomotives, passenger coaches, freight cars, and components. Broad incumbent with full-stack rail capabilities; serves as global benchmark for rail OEM scale.

Others

• Amsted Rail: US-based global supplier of railway bogies, castings, wheels, and components; strategic partner and 51% owner of related AmstedMaxion foundry. Provides GBMX with Motion Control® bogie technology. Indirect peer / enabling supplier of rail components.

• Trinity Industries: NYSE-listed (TRN) US railcar manufacturer and rail services provider. One of the largest North American freight railcar OEMs with a portfolio spanning boxcars, hoppers, tank cars, and gondolas — directly comparable to GBMX's product mix but operating in different geographies.

Regional players

• Titagarh Wagons: Mumbai-listed Indian freight rolling stock manufacturer producing wagons, coaches, and metro cars. Comparable product portfolio to GBMX but focused on Indian domestic market and select Africa/Asia exports — a regional player with similar commodity-driven customer base.
