This initiative is designed to provide a wide range of engineering services such as design assurance, prototype sourcing, testing, and quality engineering support, catering to the needs of London Underground rolling stock components. The procurement is part of a framework agreement set to commence on 1st July 2027 and conclude on 1st July 2031. Transport for London, located at 5 Endeavour Square, London, is serving as the buyer. Interested parties must submit a Market Sounding Questionnaire by 26th June 2026, which marks a critical deadline in this planning phase. This procurement offers a significant opportunity for businesses involved in engineering design, support, technical consultancy, and related services. Companies skilled in providing competitive and alternative solutions for rolling stock components would be well-positioned to compete for a portion of this framework agreement, valued at £4.5 million net. By engaging in this tender, businesses can potentially establish long-term collaborations with Transport for London, contribute to significant cost-saving measures, and amplify their market presence in the UK engineering services sector. ## Notice Procurement of a Framework for the provision of end-to-end engineering services, including design assurance, validation through prototype sourcing and testing, support to competitive tendering, and quality engineering support for the mass production of reverse-engineered components. The purpose of the framework is to deliver financial savings to TfL by enabling alternative and competitive sources of supply for London Underground rolling stock components. This engagement mirrors the "Alternative Equipment Manufacturer Framework" Notice published by TfL on 11 June 2026 (2026/S 000-056077). It was identified that the procurement title could be misleading, as this engagement is not intended to procure manufacturers of goods and as such the title has been revised. If you have already responded to the previous UK2: Preliminary Market Engagement Notice, there is no need to submit a further response. Your previous submission has been retained and will be considered alongside any responses received to this revised notice. ### Planning Information Please express your interest in this planned procurement by emailing SamWalden@tfl.gov.uk - a link to a Market Sounding Questionnaire and supplementary information will then be shared with all interested parties.
