Supporting public authorities, infrastructure owners, and operators from early strategy to system delivery and operational excellence.
With deep public-sector roots and global experience, we offer independent, implementation-focused advice - helping shape sustainable, reliable rail and transit systems that deliver real-world impact.
We provide advisory to some of the most ambitious and transformative digital railway initiatives across Europe and the Americas - guiding programme management, strategic planning, and the implementation of advanced signalling systems.
With deep expertise in ETCS and CBTC deployment, our work spans large-scale deliveries and complex upgrade environments - from metro networks to national mainlines. We’ve been integral to helping public agencies, operators, and delivery partners navigate complexity, manage risk, and drive results.
We don’t just support delivery - we help shape and optimise the future of mobility and infrastructure networks. Explore a selection of our work below.
