Our TCMS products have received a significant power boost with the introduction of the CPU6000 Series. But what exactly is this new range of CPUs from EKE‑Electronics, and why does it matter?
Introduction
The CPU6000 Series is a scalable processing platform designed to support the core functions of a Train Control and Management System (TCMS). It provides the computing foundation for Vehicle Control Units, communication systems, and other onboard subsystems, ensuring reliable operation across a wide range of train applications. Built as part of EKE-Electronics’ TCMS architecture, it allows systems to be configured to match the exact technical requirements of each project.
Within the platform, different CPU variants are available to balance performance, complexity, and cost. Multi-core and single-core options enable engineers to select the most appropriate processing level for each function, without redesigning the overall system.
Why was a new CPU needed?
The CPU6000 Series was developed to respond to the increasing demands placed on TCMS systems. More connected systems, higher data volumes, and stricter operational requirements are changing how trains are designed and operated.
Traditional processing platforms often required compromises between performance, scalability, and cost. This could lead to systems that were either over-specified or limited in capability.
A different approach was needed. The CPU6000 Series provides a scalable platform, allowing each subsystem to use the right level of processing. At the same time, all components remain part of a consistent and integrated architecture.
Growing focus on cybersecurity and compliance has also influenced system design. Future systems must support long-term maintenance, updates, and evolving requirements without major redesign.
By combining higher computing capacity with flexible configuration options, the CPU6000 Series supports both current applications and future TCMS development.
Understanding the variants
The CPU6000 Series initially consists of three variants: the CPU6000, CPU6010, and CPU6030. Each module is designed to provide a different level of processing capability, allowing systems to be matched to specific application requirements. This range includes both multi-core and single-core options, ensuring flexibility across different subsystems within the same TCMS platform.
- Multi-core CPUs (e.g. CPU6000)
Designed for high-performance applications where multiple demanding functions run in parallel. These variants support complex architectures, large data volumes, and advanced control strategies.
- Single-core CPUs (e.g. CPU6010, CPU6030)
Intended for simpler or more focused applications where processing requirements are lower. These variants provide a cost-efficient option while maintaining compatibility with the wider TCMS platform.
This structure ensures that each subsystem uses only the processing capacity it needs, while remaining part of a consistent and integrated platform.
High-performance processing
Growing expectations for functionality are changing how TCMS systems are designed and operated. More onboard functions are now integrated into fewer systems, while communication networks must handle larger amounts of real-time data. Advanced diagnostics, automation features, and distributed control also increase the processing load placed on central systems.
Together, these factors create a need for higher computing capability and efficient data handling across interconnected subsystems. The CPU6000 Series addresses this requirement by combining strong processing performance with reliable communication capability.
- Designed to handle increasing system complexity and growing data volumes across connected train systems
- Supports demanding TCMS, VCU, and communication functions running at the same time
- Enables reliable data exchange across advanced architectures, including Ethernet-based networks, using high-speed networking and supporting redundancy concepts such as dual homing
As a result, the platform can manage both current system requirements and future growth without requiring major redesign.
Cybersecurity and compliance
Greater connectivity introduces new cybersecurity risks across onboard networks, external interfaces, and maintenance access points. Systems are now expected to support remote diagnostics, software updates, and data exchange, increasing potential exposure to threats.
Unlike performance requirements, these risks are not driven by functionality but by the need to protect systems over long operational lifecycles. Train builders and operators must ensure that systems remain secure, maintainable, and resilient for many years after deployment.
Regulation is reinforcing this shift. In the EU, the Cyber Resilience Act (CRA) introduces clear expectations for secure design, vulnerability management, and long-term support throughout the system lifecycle. Compliance will influence how systems are specified, implemented, and maintained.
The CPU6000 Series is designed to address these challenges from the outset, helping organisations prepare for compliance without major redesign or added complexity.
- Built with state-of-the-art cybersecurity features integrated at platform level
- Designed to support Cyber Resilience Act (CRA) requirements and secure-by-design principles
- Enables train builders and operators to meet increasing expectations for system protection and lifecycle support
- Suitable for systems requiring long-term security maintenance, updates, and compliance
As a result, the CPU6000 Series provides a CRA-ready processing platform, reducing implementation risk and supporting future regulatory alignment.
Scalable range for optimal fit
Different train projects require different levels of performance, depending on system size, architecture, and functional scope. The CPU6000 Series provides a scalable range to meet these needs.
- Multi-core and single-core variants available within one unified platform
- Select only the performance required for each subsystem or application
- Avoid over-specification, reducing unnecessary cost and system complexity
By matching processing capability to actual requirements, the platform helps maintain efficiency across the entire train system.
Safety and communication
Safe and reliable communication is essential for coordinating functions across distributed train control systems. Data must be transmitted accurately, even in the presence of network failures or degraded conditions.
The CPU6000 Series is designed to support safety functions and robust communication within this environment. It enables consistent and secure data exchange between subsystems, supporting both normal operation and fault conditions.
- Certified to SIL 2 according to EN 50129 and EN 50716
- Supports SDTv2 (Safe Data Transmission) for safe and verified communication
- Implements TRDP with dual homing to support resilient network architectures
As a result, the platform supports dependable system behaviour while meeting recognised safety and communication standards.
Automated train operation
Higher levels of automation are changing how train systems are controlled and monitored. Greater autonomy requires systems that behave predictably, respond consistently, and operate reliably under all conditions.
The CPU6000 Series is designed to support these requirements by providing stable and deterministic system performance. This ensures that control functions operate as expected, even in complex and highly automated environments.
- Designed to support Grades of Automation up to GoA 4 in line with EN 62290
- Provides predictable and deterministic system behaviour across control functions
- Enables reliable operation in highly automated train environments
As a result, the platform supports the transition towards higher levels of automation without compromising reliability or control.
Next-generation TCMS platform
The CPU6000 Series is not only a processor but also a foundation for future system development. It supports the evolution of TCMS architectures and enables new functionality.
- Acts as the processing core of future EKE-Electronics’ TCMS systems
- Supports the development of new functionality and system architectures
- Provides a consistent platform across multiple subsystem types and applications
This approach allows systems to evolve over time while maintaining compatibility and reducing integration risk.
Summary
The CPU6000 Series is a scalable processing platform designed for TCMS applications, combining performance, cybersecurity, and flexibility. Multi-core and single-core variants allow each system to be configured precisely, ensuring the right balance between capability and cost. As the processing core of EKE-Electronics’ next-generation TCMS platform, it provides a stable foundation for both current projects and future developments.
