A railway infrastructure operator implemented a smart-grid pilot on a major high-speed rail corridor to improve the monitoring and management of traction-power infrastructure, including electrical substations. The solution integrates telecontrol systems, energy meters, network analysers and an enterprise IoT platform, centralising consumption, power-quality and operational information in real time. This digital foundation supports a more proactive approach to energy management, asset maintenance and infrastructure reliability.

Following a major cyberattack affecting a railway infrastructure manager, NTT DATA delivered incident-response and compromise-recovery services to assess the impact, contain the threat and restore control over critical technology infrastructure. The engagement included analysis of compromised accounts, access paths and persistence mechanisms, recovery of affected workstations and servers, and review of the security tools operating in the environment. The response combined crisis execution with a structured path towards stronger monitoring, resilience and preparedness
