The judgement call

Account action unavailable

The project highlighted the importance of thorough testing and addressing human factors (e.g., driver visibility) early in the design and commissioning phases to prevent service delays. - The use of a leasing arrangement with Caledonian Rail Leasing demonstrated a common financing model for rolling stock procurement in the UK. - The introduction of the Class 385 facilitated the cascade of older diesel multiple units, contributing to network modernization and decarbonization efforts. - Hitachi's Fleet Monitoring Tool and a balanced examination system were implemented for maintenance, emphasizing data-driven approaches to fleet management and reliability.

Key engineering challenges

Adapting the global AT200 platform to specific UK and Scottish operational requirements, including crashworthiness and driver ergonomics for a front-end corridor connection. - Overcoming initial delays due to infrastructure works and minor technical issues, including driver visibility concerns with window curvature. - Integrating the fleet into newly electrified lines and ensuring compatibility with existing infrastructure. - Managing manufacturing across international sites (Japan for bodyshells, UK for assembly) while maintaining quality and local content requirements.
