Challenge
Knorr-Bremse Rail Systems Budapest employs nearly 2,000 people, including around 400 engineers in development, and works on next-generation brake control electronics. The rail industry is marked by highly varied customer requirements and shifting project priorities, so the company needed a partner able to deliver complex software and hardware work reliably while adapting flexibly to changing needs.
Solution
Sigma Technology Hungary began the partnership in 2017 by producing technical documentation and has since expanded its role step by step. In 2023, this grew to include embedded-systems testing and software development. Today the collaboration centers on brake electronics, diagnostics solutions and cybersecurity compliance for next-generation brake control systems.
Results
Over eight years, the partnership has grown into a broad collaboration spanning technical documentation, testing and software development, successfully managing team transitions and shifting resource needs along the way. According to Knorr-Bremse, Sigma Technology has built up substantial domain knowledge over time, which has been a clear advantage for the cooperation.
