    Brief

    Chiltern Rail Limited is seeking market information for replacing its Trackside Acoustic Detection System (TADS), which has monitored train axle bearing health since 2015 but is becoming unreliable. TADS uses microphone technology to detect defective bearings before failure, supporting critical safety and operational decisions. Chiltern is conducting preliminary market engagement to understand available solutions and delivery models. The replacement scope may include: system design and Network Rail approval, decommissioning existing equipment, civil engineering, equipment installation, user interface and software development, and ongoing maintenance and support. Chiltern is seeking supplier input on: available commercial models, indicative pricing, implementation timescales, functional and non-functional requirements, and key cost drivers. This is preliminary market engagement only and does not constitute a formal tender invitation. The final contract value, duration, and procurement structure have not been determined. Suppliers should provide information on commercial options, pricing, implementation schedules, and factors affecting cost to help Chiltern develop its procurement strategy.
