LEROY Automation : Excellence in TCMS for Smarter Trains
With the rise of digitalization and smart transportation, LEROY Automation stands out as a key player in the railway sector with its advanced solutions for TCMS (Train Control and Management System). This system, the true orchestrator of modern trains, optimizes performance, maintenance, and safety of rolling stock. Let’s dive into the world of TCMS and the innovations pioneered by LEROY Automation.
What is TCMS and what is its role in a train?
The TCMS, or Train Control and Management System, is the neural center of the train. It orchestrates all critical functions: traction, braking, door operation, air conditioning, lighting, and more. At LEROY Automation, we design embedded solutions that comply with railway standards, ensuring efficient management, simplified maintenance, and reduced operational costs for operators.

How does TCMS improve train maintenance?
LEROY Automation’s TCMS solutions enable trains to transmit crucial real-time data to maintenance teams. With high-performance onboard computers, any anomaly is instantly reported, allowing proactive interventions and reducing downtime. Our systems facilitate effective predictive maintenance, ensuring maximum availability of rolling stock.
What role does connectivity play in TCMS operations?
The advancement of connected technologies (4G, 5G, IoT) has transformed TCMS into a true data exchange hub between the train and ground infrastructure. LEROY Automation integrates these innovations to provide interconnected solutions, enabling real-time updates for passenger information, remote monitoring of onboard equipment, and optimized railway operations.
What are the future developments for TCMS?
TCMS is evolving towards a more centralized and software-based architecture. At LEROY Automation, we develop solutions based on a single high-speed Ethernet network, capable of managing all train functions with greater flexibility. The integration of IoT sensors allows enhanced monitoring of equipment, further improving predictive maintenance and railway resource management.
What are the cybersecurity challenges of TCMS?
With the increasing data exchanges between the train and ground infrastructure, cybersecurity has become a top priority. LEROY Automation designs TCMS solutions that incorporate secure communication protocols, advanced firewalls, hardware data diodes and powerful monitoring tools. The goal is to ensure data integrity and confidentiality while guaranteeing reliable and highly secure train operations.
Conclusion
Thanks to LEROY Automation’s innovative solutions, railway operators benefit from a robust and scalable TCMS, addressing the challenges of intelligent and more secure railway transport.
