Engineering Vehicles (EV) - Heavy Overhaul of London Underground Switch Tilter (LUST) Wagons

Transport for London (TfL), on behalf of its subsidiary London Underground Limited (LUL), is undertaking early market engagement for the heavy overhaul of the London Underground Switch Tilter (LUST) wagons and associated lifting accessories. The LUST fleet forms part of the Modular Points and Crossings (MPaC) system and consists of 8 LUST wagons, 6 lifting beams, and 64 pairs of cross & connecting beams. These assets support the transportation and installation of pre‑fabricated Points & Crossings panels across London Underground and Network Rail infrastructure. TfL seeks to engage with the supply market to understand capability, capacity, and viable delivery approaches for a comprehensive heavy overhaul programme, including (but not limited to): • Full overhaul of all mechanical, structural, hydraulic, pneumatic, electrical, and safety‑critical systems. • Overhaul of all associated lifting beams, panel grabs, tandem lift beams and cross/connecting beams. • Completion of functional, static and annual maintenance tests as defined within the LUST Maintenance Manual. • LOLER inspection, NDT, structural repairs, repainting, and component replacement as required. • Production of full overhaul records, assurance certificates, and traceability documentation. This engagement aims to gather supplier feedback on methods, timescales, delivery sequencing, challenges, and risks, to shape the forthcoming procurement strategy.
