Railway construction safety technology in ESA project

Railway construction safety technology is the focus of a new project launched by ESA and the UK-based company Tended, as reported by Railway Pro.

The initiative is intended to improve safety and efficiency in rail infrastructure works. It centers on the Virtual Worksite Marker Board (VWSMB), a digital system meant to replace physical signs at work zones.

Railway construction safety technology in practice

This phase builds on the Digital Worksite program launched in 2023. It is focused on improving the system’s accuracy and reliability in real-world operating conditions.

The VWSMB uses geospatial data to establish virtual boundaries for railway work sites. Also, a device in the cab of work machinery positions itself relative to those digital limits. If an operator goes beyond the authorized area, the system immediately triggers an alert.

Replacing physical boundary panels also reduces the need for personnel to enter the infrastructure. In addition, it reduces the need to install and remove those panels on site. At the same time, this lowers risk exposure and reduces the likelihood of delays.

UK railway trials and operating results

The technology has already been tested in pilot projects in the British rail sector. For example, one trial with Siemens Mobility is estimated to have generated savings of more than GBP 130,000 by reducing work overruns. Meanwhile, a separate test with Network Rail on the East Coast line saved about 45 minutes during a work window. It also extended the available time for works by around 17%.

The solution is already in use in Scotland by SPL Powerlines and Network Rail Scotland. Separately, initial deployments there have delivered time savings of about 30 minutes per shift. They have also reduced the travel required to install physical panels.

ESA positioning technologies and next steps

Under the new project with ESA, the system will incorporate positioning technologies based on space infrastructure to improve accuracy. Still, the aim remains the same. It is to develop a solution capable of operating reliably in challenging environments, including areas with limited visibility or complex infrastructure.

The project will also explore whether the technology can be used to track and manage equipment at railway construction sites. Meanwhile, that work is intended to help modernize the planning and coordination of infrastructure works.
