Railway Computer System For Safety-Critical On-Board and Trackside Applications

menTCS is an open and modular railway computer platform, and is the first-ever railway system to be based exclusively on defined open standards for hardware, software and communication.

menTCS is well suited for control of all safety-related functions in new train models as well as for refurbishment of trains. Thanks to its modularity, it is easy to install and retrofit automation functions in combination of menTCS with other parts of already existing train control equipment as well:

  • Installation as the heart of the CBTC (Communication Based Train Control) or PTC (Positive Train Control) system or the TCMS (Train Control Management System) for new trains
  • Increase in efficiency of already existing ATO, ATP and ATS functions as the central computer
  • Step-by-step replacement of older equipment, resulting in one standardized general-purpose platform for all safe applications
  • Can be combined with additional remote control components sitting directly at the door, at the wheel, at the gear
  • All-in-one safe control system and non-vital communication system – safely separated through strict partitioning
  • Interfacing to all existing train communication with Ethernet and MVB, CAN bus etc
  • Interfacing to the driver cab display
  • Interfacing to wireless communication with the outside world through GSM-R, GPS, Wi-Fi etc
  • Decrease in life cycle cost through easy maintenance of standard components
  • Longer operating life by using standardized technologies

Consisting of the safe controller, the safe I/O functions, and the communication interfaces to the "outside" world, menTCS is certifiable up to SIL 4 in its single parts and complies with the EN 50126 (RAMS), EN 50128 (software) and EN 50129 (hardware) railway development standards for functional safety.

The robust and rail-ready menTCS components comply with the railway standards for environmental and EMC conditions EN 50155 (rolling-stock) and EN 50125-3 / EN 50121-4 (signalling/wayside).

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.
