Unstad has developed a wireless solution for real-time monitoring and logging of gearbox oil temperature, with cloud-based data access supporting optimal operation and condition-based maintenance.

Unstad supported the client in improving the ECM process in line with EU Regulation 2019/779, with a particular focus on strengthening the interface between F3 and F4. In parallel, Unstad supported the introduction of new trainsets by updating SAP MRO and coordinating the functional breakdown structure (FBS) and maintenance data.

Unstad supports the client with brake system expertise across three vehicle procurement projects—from feasibility studies and specification development to testing and on-track trials.

Unstad optimized wheel maintenance and introduced systematic monitoring of wheel wear on Di4 locomotives. These measures doubled wheel service life from 150,000–180,000 km to 300,000–350,000 km, while reducing downtime and delivering significant cost savings.

Unstad conducted dynamic brake testing of a catenary tensioning vehicle in accordance with EN 16834, including measurement of stopping distance, brake cylinder pressure, and temperature. The tests were carried out in both empty and fully loaded conditions and verified braking performance and safety.

Risk analysis of the Type 93 tilting system, including identification of deviations and recommendations for improved operational reliability and maintenance.

Unstad carried out a large-scale fleet inspection following the Traffic Package 2 transition, establishing a technical baseline that reduced risk and provided a solid foundation for efficient fleet management and maintenance planning.

A holistic upgrade concept for the Premium interior in Type 73, with a focus on quality, functionality, and feasibility.

Unstad supported the client in upgrading the LM5 diesel engine from Tier 2 to Tier 5 through compatibility analysis and approval support. The upgrade improved environmental performance and extended the vehicle’s operational service life.

Unstad assumed technical responsibility for risk and safety management at the client and established a robust framework for risk assessments, safety protocols, and IT security improvements. The delivery included training and integration into operations, strengthening the organization’s resilience against security threats.
