Regional rail operator running four lines across North Rhine-Westphalia
National Express Rail GmbH operates four regional rail lines (RE 7, RB 48, RE 5, RE 6, RE 4) across North Rhine-Westphalia, carrying roughly 20 million passengers annually. The tech stack—MySQL, PostgreSQL, Oracle, Azure, AWS, Kubernetes—supports mission-critical passenger systems, but hiring and project activity signal internal operational friction: the company is simultaneously managing system integration, reducing downtime, and improving IT service delivery while maintaining schedules and passenger information systems. Only two engineering roles are open against 13 in ops, suggesting IT delivery strain outpaces engineering capacity.
