Summary of the contracting process

Transport for London procured shoe gears and beams for S Stock London Underground rolling stock. These are safety-critical traction-current components: the shoe gears transfer current from the conductor rail to the train, while the beams secure the materials to bogie frames or axles and provide electrical insulation from the wheelset and bogie structure. Without them, S Stock trains cannot move. The requirement is for goods associated with railway rolling stock and its components (CPV 34600000), delivered in London. The purchase is made by Transport for London for its Underground rolling-stock operations. The goods are bespoke to S Stock and form part of the train’s traction and safety systems, rather than general engineering consumables.

This procurement has been awarded through a single completed lot using a direct award. The award decision was dated 24 July 2026 and named SCHUNK CARBON TECHNOLOGY LIMITED as supplier. The award value is £11,166,441 excluding VAT, or £13,399,728 including VAT. The contract period runs from 8 August 2026 to 7 August 2031, with an extension option of up to three years, giving a maximum extent date of 7 August 2034. The proposed contract was evaluated on the basis that the goods are proprietary and technically dependent on the existing supplier: changing supplier could create incompatibility and disproportionate technical difficulties in operation or maintenance. The award notice triggered an eight-working-day standstill, ending on 6 August 2026, with signature scheduled for 7 August 2026.

This award demonstrates demand for specialist, safety-critical electrical and mechanical components used on London Underground rolling stock. A credible future competitor would need demonstrable capability to design, manufacture and supply bespoke shoe gears and beams that fit S Stock bogie frames or axles, transfer traction current reliably and maintain the required electrical insulation. Evidence of compatibility with existing rolling-stock systems, dependable continuity of supply and support for operation and maintenance would be central, because the buyer justified the direct award on technical dependency and the risks of incompatibility. Relevant railway-sector manufacturing experience, robust quality assurance, traceability and the capacity to supply consumables when required would strengthen a supplier’s position when this requirement is next considered.
