Vehicle Integration

Vehicle integration of ETCS onboard systems are a major cost driver and a high project risk. 

Besides special solutions based on TCMS retrofit and -extension, we work with industry and operators to define the future standard interfaces that will find their way into TSI releases in the next decades.

RGY VS - modular and scalable ETCS OBU

RGY-VS is our ETCS NG.

Built on 7 years of experience, starting with openETCS and having evolved to a DMA (Distributed Modular Architecture) system concept, RGY VS is on a trajectory for demonstration in 2022. 

Stay tuned. 

For more information, please contact us


We provide support and consulting to all stakeholders in ETCS projects, with a focus on architecture, integration, and long-term evolution

#ETCS Solutions

TCMS Retrofit and Integration

One of the biggest challenges in retrofit is the engineering of the connections between the Onboard Units of the CCS systems (like ATO and ETCS) and the control systems of the vehicle. 

If you have a old Diesel loco, an EMU or a modern locomotive with a digital TCMS: Our modular approach and our deep knowledge of existing and emerging standards such as Subset-119 and Subset-139 enable us to find an economical solution for your retrofit project.

Lab Vehicles


For Lab vehicles, we have a portfolio of special solutions. 5G Remote Control, emulation of different TCMS systems, survey systems--- challenge us!

Safe Location

For ETCS level 3, for ATO and for other CCS applications, a safe and precise vehicle position information is essential.

Traditional solutions (based on radar) are expensive and hard to retrofit. 

Pure GNSS solutions lack availability and it is very difficult to demonstrate continual integrity of the positioning solution. 

Our Vehicle Locator system is based on fusion of:

- Intelligent topology- matching technology, based on AI and protected by a SIL4 safe position envelope algorithm

- IMU- based short- term positioning, making sure that the immediate trajectory is fused with the topology- matching information

This solution is augmented by an integrated solution based on a complex Kalman- Filter that uses information from wheel- speed sensors, dual GNSS receivers (336 channels, GPS, GLONASS, Galileo and BeiDou constellations). 

The system can be configured for different levels of positioning accuracy. (0,5m, 0,1m, 2cm) depending on your requirements (subscription fees may apply).

No radar or lidar sensors are required for a safe vehicle location. The system can be retrofitted to legacy rolling stock. 

The interfaces are compliant to the relevant standards. A BTM emulation mode (for virtual balise approach) is available as an option. 

Please contact us for further information.
