What makes it different?
Traditional chatbots follow scripts. The GB Rail Assistant is powered by agentic AI, which means it doesn’t just respond - it thinks, reasons, and acts.
​It pulls information from multiple trusted sources.
It doesn’t rely on static flows. It adapts to each question, even when circumstances change mid-journey.
It combines steps to solve complex problems like re-routing during a disruption without human intervention.​
