Case Study: Nextrail GmbH achieves 10,000x faster ETCS brake simulation with Brightgrove

Nextrail GmbH builds ETCS brake simulation 10,000x faster with Brightgrove

Nextrail GmbH, a key partner in modernizing rail transport, faced the challenge of developing a highly scalable simulation framework to compute Gamma braking parameters for ETCS-compliant vehicles. This was essential for improving operational performance and maximizing line capacity. Brightgrove was engaged to build this software solution.

Brightgrove engineered a vectorized simulation framework using Monte Carlo methods and JAX for computation. The solution included graph node reduction and GPU acceleration, which resulted in performance improvements of 10,000 times faster than classical approaches. This allows Nextrail GmbH to perform large-scale scenario analyses under varying conditions, providing actionable insights for vehicle design and operational planning.
