A large number of Alstom\u2019s legacy Electrostar fleets have long relied on a specific model of Door Control Unit (DCU), which recently entered obsolescence as declared by the OEM. Alstom required a repair partner who could not only restore performance of the DCUs but do so with long-term sustainability and cost efficiency in mind.<\/p>\n

Enter TP Matrix<\/strong><\/span>\u00a0\u2013 specialists in electronic repair and overhaul within the rail sector. With deep experience in obsolescence management and complex systems testing, TP Matrix partnered with Alstom to develop a proactive, scalable repair solution for the entire fleet.<\/p>\n

The task involved two primary challenges:<\/p>\n

    \n
  • Restore failed DCUs to full operational condition, post in-service failure<\/li>\n
  • Navigate and mitigate obsolescence risks, ensuring repairability over time<\/li>\n<\/ul>\n

    With over 6000 units in service and OEM replacements no longer an option, the economic implications of a full system replacement were significant \u2013 potentially running into millions of pounds across the fleet. TP Matrix\u2019s repair-first strategy offered a compelling alternative.<\/p>\n

    The predefined replacement list has proven highly effective, addressing the majority of issues found across units. Only one component has since become obsolete. TP Matrix sourced a like-for-like alternative, secured full engineering change approval, and integrated it into the mandatory change list without affecting delivery schedules.<\/p>\n

    All other components replaced during repairs have shown no obsolescence issues to date. Furthermore, TP Matrix actively monitors emerging trends in component failures and adapts the repair scope in real time.<\/p>\n

extending asset life and avoiding costly fleet-wide replacement.Developed a bespoke automated test system - enabling accurate fault diagnosis, comprehensive functional testing and faster turnaround times.Achieved zero units deemed unrepairable due to obsolescence - through proactive component replacement and ongoing obsolescence management.BackgroundA large number of Alstom\u2019s legacy Electrostar fleets have long relied on a specific model of Door Control Unit (DCU), which recently entered obsolescence as declared by the OEM.
