Production Française Made in France

Rail industry

In order to play an essential role in modern mobility, Cordm offers an advanced expertise in the manufacture of mechanical reducers and gears, critical components for main  manufacturers of rail transport vehicles, whether metros, high-speed trains or freight trains. Thanks to its many years of experience and advanced technological expertise, Cordm is a key player in the sector, actively contributing to optimizing the performance and safety of rail transport systems worldwide.

Concerning metro systems, reliability and performance are fundamental requirements for guaranteeing regular, trouble-free service. Subways, which are often subjected to intensive duty cycles and varied operating conditions, require particularly reliable components. That’s why our gears are specially manufactured to offer exceptional durability and low maintenance requirements. By using high-quality materials and state-of-the-art manufacturing processes, our gears ensure smooth, trouble-free operation, even under heavy-duty conditions. This reliability not only optimizes metro performance, but also extends their service life, while reducing maintenance and operating costs for operators.

Speaking about high-speed trains, high speed and safety are essential criteria that must be rigorously balanced. To meet the stringent performance requirements of high-speed trains, our gears are designed to deliver optimum power transmission while minimizing wear and vibration. These gears undergo rigorous testing and strict quality controls to ensure they comply with all international standards and certifications in force in the rail industry. The results obtained guarantee high performance and maximum safety, even at extreme speeds.

Moreover, our commitment to innovation and continuous research enables us to offer ever more effective solutions, adapted to the changing needs of the rail industry, in a context where reliability, safety and durability are more than ever paramount issues. Cordm is therefore the partner of choice for manufacturers and rail transport operators, ensuring both product quality and service excellence.
