Transport for London’s (TfL) Automated Track Monitoring System (ATMS) is a modern condition monitoring system, essential for the efficient and safe operation of its rail infrastructure. However these Infrastructure Monitoring systems are prone to obsolescence over time, where components can become unavailable, spare parts scarce, and the costs of maintaining aging technology increasingly complex.
TfL were seeking to extend their ATMS Systems’ operational service life, and required a structured approach to mitigate future risks and ensure continued Infrastructure Monitoring data availability.
CPC was engaged to conduct a Residual Life Assessment for ATMS, delivering a strategic roadmap to enable this service life extension. This proactive study has helped TfL anticipate the actions and resources required to maintain ATMS beyond its original design life while ensuring operational continuity.

Background
ATMS provides critical infrastructure condition monitoring and performance data across TfL’s network, supporting safety and operational efficiency. The system has been successfully maintained to its design life with cost-effective management and has provided a reliable supply of output data. However, extending its operational service life introduces new risks, particularly regarding obsolescence and long-term sustainability.
Key components, such as the Inertial Platform and Digital Video Recorder, were becoming harder to source, increasing the complexity of long-term maintenance. The growing risk of obsolescence necessitated a systematic approach to anticipate future maintenance needs and identify the actions and resources required to sustain ATMS operations effectively.
The Challenge
Extending the operational service life of TfL’s ATMS presented several critical risks:
- Subsystem obsolescence – Aging hardware and diminishing support from suppliers posed long-term sustainability challenges.
- Reliability analysis – Enhancing fault reporting was essential to enabling a more comprehensive predictive maintenance strategy.
- Future cost considerations – Understanding the long-term financial impact of different service life extension scenarios was key to making informed mitigation decisions.
- Operational resilience – Ensuring a sustainable supply of data and maintaining system integrity as components age required a structured and proactive approach.
CPC’s Role
CPC delivered a holistic Residual Life Assessment, combining technical expertise with a forward-looking approach to ensure actionable outcomes.
Key aspects of our role included:
- Subsystem Risk Analysis – Conducted detailed obsolescence risk assessments for ATMS components, prioritising interventions based on criticality, failure probability, and operational impact.
- Enhanced Data Utilisation – Improved fault reporting processes to support predictive maintenance planning and trend analysis.
- Lifecycle Planning – Developed a phased roadmap with clear actions and cost projections to extend service life of ATMS.
- Knowledge Transfer – Collaborated closely with TfL teams to embed solutions into operational workflows, ensuring long-term sustainability.
Key Outcomes
This proactive study looking ahead at what was needed to achieve TfL’s objectives delivered significant benefits, including:
- Service life extension – A clear roadmap enabled TfL to plan for the continued operation of ATMS beyond its original design life.
- Obsolescence mitigation – Practical spare part management strategies minimised risks from aging hardware.
- Lifecycle extension – A clear roadmap provided TfL with the confidence to extend ATMS service life
- Operational efficiency – Consolidated system data into a central repository, enabling informed decision-making and reducing reactive interventions.
Interventions
CPC delivered targeted solutions to address obsolescence and enhance system performance:
- A comprehensive obsolescence risk framework for ATMS components, enabling prioritised interventions.
- Lifecycle cost analysis and roadmap development, supporting sustainable decision-making.
- Collaborative workshops to ensure solutions were practical and aligned with TfL’s operational goals.
