Engineering Excellence: The Development Cycle of a Train Control and Monitoring System (TCMS)

A Train Control and Monitoring System (TCMS) serves as the central nervous system of modern trains, orchestrating critical functions such as traction, braking, door operations, air conditioning, and lighting. The development of a TCMS follows a structured life cycle to ensure safety, reliability, and compliance with stringent railway standards.​

1.

Needs Analysis & Specification Development

The initial phase involves a comprehensive analysis of operator and manufacturer requirements. This includes ensuring compliance with Safety Integrity Level (SIL) standards and adherence to EN 50155, EN 50126, EN 50128, EN 50129, and EN 50159, which govern electronic equipment, software, and system reliability in railway applications. LEROY Automation and MIOS Elettronica, as designers of onboard electronic systems, play a pivotal role in assessing and defining these specifications, leveraging their expertise to align with industry standards and client needs. ​

2.

System Design & Development

In this phase, the hardware and software architectures are meticulously crafted. Integration of communication protocols such as RS-485 (PROFIBUS), CANopen, MVB, and Ethernet (TRDP, CIP – EtherNet/IP, IPTcom, etc) is essential for seamless interoperability between subsystems. As a system architect, LEROY Automation contributes significantly by providing Programmable Logic Controllers (PLCs) and Remote Input/Output (I/O) modules designed for automation and control tasks within the TCMS framework. Their products are engineered to meet EN 50155 standards, ensuring durability and performance in the demanding railway environment.

3.

Integration & Testing

This critical stage involves the validation of software and rigorous testing of system performance under real-world conditions. Assessments focus on the system's resilience to shock, vibration, and temperature variations, ensuring compliance with industry regulations. Collaborations with specialized testing entities, such as TAME-TEST, facilitate comprehensive evaluations, verifying that the TCMS meets all operational and safety standards.​

4.

Certification & Deployment

Achieving certification necessitates strict adherence to CENELEC standards, including EN 50126, EN 50128, and EN 50129, which collectively address system reliability, software integrity, and safety. Following certification, the TCMS is installed on-board, commissioned, and subjected to final testing. Operator training programs are implemented to ensure proficient system management, and long-term maintenance strategies are established to sustain optimal performance throughout the system's operational life.​

By meticulously navigating each phase of this life cycle, stakeholders ensure the development of TCMS solutions that are not only reliable and high-performing but also fully compliant with the rigorous demands of the railway industry.
