## Summary

Transport for London (TfL) has initiated the Central Line Signalling Incremental Upgrade Project, presently in the planning stage. This project, classified under installation services of guidance and control systems, aims to progressively upgrade the Central Line's signalling and train control systems over the next 20 years. The current procurement activity includes a Market Sounding Questionnaire (MSQ) to assess market capability and interest, with responses due by 15th October 2021. An Industry Day is scheduled for 28th September 2021, providing potential bidders with support to complete the MSQ and to address any queries.

This tender presents significant opportunities for businesses involved in transport infrastructure and technological upgrades, particularly those specialising in signalling systems, automatic train control, and related engineering services. Companies capable of offering innovative solutions that enhance system reliability and lower long-term costs would particularly benefit, as TfL seeks to form long-term supplier relationships through this gradual upgrade approach. Engaging early through the MSQ and attending the Industry Day will be pivotal for suppliers aiming to shape their involvement in this extensive project.

## Notice

Transport for London (TfL) is issuing a Market Sounding Questionnaire (MSQ) as part of the Early Market Engagement (EME) activity for the Central Line Signalling Incremental Upgrade Project (CSIP). The purpose of the MSQ is to improve TfL's understanding of market/supplier appetite, capacity and capability, as well as perceived risks and opportunities to TfL's proposals for an incremental approach to the renewal and upgrade of the Central Line (CL) Signalling & Train Control (S&TC), meaning the signalling, signalling control and automatic train control systems, together with associated infrastructure. The EME activities are being undertaken to inform the overall scope of works planned over the next 20 plus years that are proposed to progressively renew and upgrade the current CL S&TC with new equipment and systems.
