Hitachi Rail has entered into an agreement with The Copenhagen Metro to implement a customized version of its HMAX (Hyper Mobility Asset Expert) digital asset management system across the M3 and M4 metro lines. This advanced system, powered by Nvidia technology, will integrate real-time data from the metro’s trains and tracks into a unified infrastructure monitoring platform, enhancing both operational efficiency and maintenance procedures.

This long-term initiative builds on a partnership with The Copenhagen Metro that spans over twenty years. As part of the agreement, Hitachi Rail will equip metro trains with advanced sensors that monitor vibrations and gather detailed data on various vehicle subsystems, including the health of bogies and wheelsets, as well as track conditions. This data will feed into the HMAX system, which utilizes robust AI to significantly improve data analysis speed, accuracy, and utility. This enables proactive maintenance and operational optimizations, such as identifying the best speeds for different segments of a journey to enhance reliability.

Edoardo La Ficara, Hitachi Rail, said: “Delivering our cutting-edge digital asset management programme marks an important evolution in our long running partnership with The Copenhagen metro. The programme will see us install sensors on the metro trains to provide live-time data into a bespoke and integrated version of our HMAX infrastructure monitoring platform. Our pioneering HMAX solution will use machine learning to deliver an even more reliable service, while shifting the fleet from a time-based to a condition-based maintenance approach.”

Søren Boysen, Executive Director at The Copenhagen Metro, said: “Our co-creation process with Hitachi Rail on the HMAX technology will give us a new understanding and insight for evolving condition-based maintenance on our transport systems. With service availability higher than 99 % in 2023, we aim to keep that level by continuing exploring new ways to conduct maintenance together with our current and future suppliers and thus maintaining high passenger satisfaction in The Copenhagen Metro”.

The implementation of HMAX aims to transition The Copenhagen Metro from traditional time-based maintenance to a more efficient condition-based approach. By analyzing sensor data, the system can detect early signs of wear or misalignment in train components, allowing for timely, cost-effective repairs that extend the lifespan of critical infrastructure and reduce downtime.

The announcement of HMAX occurred earlier at the InnoTrans rail conference in Berlin, where Hitachi Rail showcased the platform’s capacity to revolutionize train service management through NVIDIA’s AI acceleration. The bespoke HMAX solution for The Copenhagen Metro is slated for completion by the end of 2025, under the existing operations and maintenance contract for the M3 and M4 lines.
