Every time a train glides safely into a British station, there's an invisible force at work. RSSB isn't a train operator or a government regulator—it's the independent safety brain of Great Britain's railways, orchestrating standards that touch every track, signal, and passenger.

"RSSB doesn't run trains—it runs the safety standards that make every train run possible."

The real genius of RSSB's model lies in its independence. As a not-for-profit company limited by guarantee, it operates free from shareholder pressure while maintaining the credibility to set binding standards. This allows them to focus on long-term safety research—like their work on level crossing safety or driver advisory systems—that commercial operators might deprioritize.

• Sets mandatory technical standards for track circuits, signaling, and rolling stock
• Conducts independent safety research on emerging risks (AI, electrification, climate adaptation)
• Operates as a knowledge broker, aggregating data from 28 operators to identify systemic risks
• Funds and coordinates cross-industry safety initiatives that no single operator could justify alone
