The menTCS Approach

menTCS - the MEN Train Control System is the first computer system ever, in the history of the railway industry, that is based on defined open standards for hardware, software and communication. Modularity makes it configurable for every control function inside and outside the train – and scalable to any required safety level from SIL 2 up to SIL 4.

The use of digital technology has transformed the way modern railways work today. To meet the challenges of railway digitalization, computer systems must be built around open standards, especially for safety-related functions in order to make rail transport means for passengers and freight sustainably competitive and safe. menTCS is application-ready and allows the immediate start of the application development, giving the user complete control over the functionality of the entire system. The benefits include:

  • Open safe platform with SIL 4 from the start
  • One platform for wayside and rolling stock
  • Reduced development cost and obsolescence risk
  • Standard open source software interfaces for flexible and easy installation of applications
  • No proprietary end application for non-restrictive use
  • Open communication extensions allow integration in all existing railway applications
  • Future-proof solution providing the same functionality without time limitation
  • Open standards ensure independence of single supplier
  • Pre-certified hardware for fast time-to-market and low certification risk

The menTCS Modular System

General Information

menTCS is an open and modular railway computer platform based exclusively on standard hardware and software. It is certifiable up to SIL 4 in its single parts and complies with the EN 50155 and EN 50125-3 / EN 50121-4 railway standards.

The train control system is designed to operate in rolling-stock applications such as Automatic Train Control (ATO) and Automatic Train Protection (ATP) as well as in wayside applications like interlocking systems. The modular Train Control System from MEN consists of the safe controller, the safe I/O functions and the communication interfaces to the "outside" world.

Its modular configuration enables the menTCS system to communicate with other train systems like service or diagnosis units via any type of wired or wireless interface. Additionally, fieldbus interfaces can be implemented to connect into other networks like MVB, CAN, Profinet etc. This makes it easy to integrate into a TCN network as well as into regionally different Train Control Systems like PTC, ETCS, CTCS, ATCS or Klub-U.

Let MEN design your individual safe computer system based on our long-standing experience in the realization of mission-critical electronics.

Systems with Single Building Blocks

The heart of the modular MEN Train Control System is the menTCS controller which delivers state-of-the art computing performance based on x86 PC technology. The menTCS controller consists of a safe part and what is called an “unsafe” (general purpose) part. The menTCS controller can be used as a standalone device and in combination with up to 63 remote I/O boxes.
