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. ## CPV classification Installation services of guidance and control systems Source Find a Tender (UK) · Notice ocds-h6vhtk-02d3a7-2021-09-30T18:12:25+01:00 [View official notice](https://www.find-tender.service.gov.uk/Notice/ocds-h6vhtk-02d3a7-2021-09-30T18:12:25+01:00) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
