Railway operations leave very little room for hesitation. When something goes wrong, staff need the right information immediately, not after digging through pages of manuals. That is the problem Keio Corporation is trying to solve with a new AI backed communication setup across its railway operations.
The company has begun operating an integrated system that connects the frontline communication platform Buddycom, developed by Science Arts Co., Ltd., with its internal generative AI tool called KEIO AI-Hub. The system went live on March 10, marking the first case where Buddycom is directly linked with an AI trained on internal railway manuals.
Keio had already rolled out Buddycom to station staff and train conductors back in 2022 to speed up coordination during incidents and improve information sharing. The latest integration takes that a step further. Staff can now ask questions through voice or text inside Buddycom, and the AI searches company regulations, operational rules, and crew manuals before returning a summarized answer instantly through text and voice.

Railway operations depend on strict procedures and quick judgment, especially during disruptions or emergencies. Searching through manuals during such moments slows things down. With AI automating search processes, the intention is to speed up response to actions by making staff act faster and in a more accurate manner.
The integration is powered through Buddycom’s API capability, which allows the platform to exchange data with external systems. This also opens the door for connections with other technologies such as AI cameras and recording systems, where alerts about suspicious activity or specific individuals can be delivered instantly through voice notifications.
Science Arts sees this as a larger shift. Buddycom is gradually moving beyond a simple voice communication tool into a platform where people, AI, and operational systems interact in real time. The idea is straightforward. Workers speak, AI analyzes the situation, and the system surfaces the information needed to act without delay.
