In collaboration with the European Space Agency (ESA), UK-based company Tended is introducing new technology designed to make railway construction safer and more efficient. By using space-based positioning systems, the initiative aims to modernise how worksites are managed. This approach is designed to reduce risks for workers and streamline construction operations.
Advancing the Virtual Worksite Marker Board
The project builds on Tended’s Virtual Worksite Marker Board (VWSMB). It is a digital system that replaces traditional physical markers used to define railway work zones. Following the success of the Digital Worksite programme launched in 2023, the next phase focuses on improving the system’s accuracy and reliability under real-world conditions.
How VWSMB Works
VWSMB technology creates virtual boundaries for railway worksites using geospatial data, eliminating the need for physical markers. A device installed inside the cab of work machinery continuously monitors its position relative to the virtual boundaries. If an operator moves outside the authorised area, the system automatically triggers an alert.
By removing the need for workers to install or retrieve physical panels, the system lowers safety risks and minimises delays. The automated approach also reduces human error and increases overall site efficiency.
Enhancing Accuracy With Space-Based Technology
The next stage of the project focuses on improving precision through satellite signals. The space-based positioning provides real-time, accurate location tracking. It ensures reliable performance even in challenging environments, such as tunnels, bridges, or areas with limited visibility.
Successful Pilot Projects Across the UK
The VWSMB system has already been tested in pilot projects throughout the UK railway sector. In collaboration with Siemens Mobility, one trial reportedly saved over GBP 130,000 by reducing work overruns.
Another test on the East Coast line with Network Rail cut approximately 45 minutes from a work window, effectively increasing available working time by 17%. In Scotland, early deployments with SPL Powerlines and Network Rail Scotland have saved approximately 30 minutes per shift. They have also reduced the travel required to install or remove physical panels.
A Step Forward in Digital Worksite Management
By integrating space-based technology, the VWSMB system is set to deliver improved precision and reliability, particularly in complex or hard-to-manage construction sites. With backing from the European Space Agency, the project offers a safer, more efficient, and more modern approach to railway construction. It also represents a huge step forward in digital worksite management.
