Summary of the contracting process

Transport for London bought overhaul services for two DISAB TubeVac machines supporting London Underground engineering vehicles and rolling stock. These are specialised rail-mounted vacuum units used during ballast track renewals and track maintenance to remove ballast, dust and debris, helping keep railway infrastructure clean and safe and reducing maintenance downtime. The requirement covers railway vehicle maintenance and associated repair services, including the overhaul work and parts identified through condition assessment once the machines are taken out of service. Delivery is for Transport for London’s railway operations in the United Kingdom, with the work relating specifically to London Underground engineering vehicles. This is a single services requirement, suitable for small and medium-sized enterprises, although the selected supplier is the machine manufacturer’s UK company, DISAB UK Limited.

The procurement is complete and the contract has been awarded to DISAB UK Limited. Transport for London used a direct award under the utilities regime, relying on exclusive intellectual property or other exclusive rights and stating that there were no reasonable alternatives. The award was made on 12 February 2026, with an awarded value of £1,449,392 excluding VAT and £1,739,271 including VAT. The contract was signed on 3 August 2026 and runs from 1 September 2026 to 31 March 2027, with a possible extension to 31 March 2028. Its value is £1,460,984 excluding VAT and £1,753,181 including VAT. Additional purchases may follow condition assessment, and extensions may accommodate justified changes to overhaul requirements or schedules.

This award demonstrates demand from Transport for London for specialist overhaul of DISAB TubeVac rail-mounted vacuum equipment used in London Underground maintenance. A credible future competitor would need technical capability to inspect, repair and overhaul this type of manufacturer-specific machinery, source and fit any additional parts identified during assessment, and support equipment used in safety-critical railway engineering environments. The buyer’s chosen route indicates that intellectual property, exclusive rights and access to original equipment expertise were central to supplier selection, so businesses would need to demonstrate an equivalent authorised, proprietary or otherwise exclusive technical position where relevant. They would also need sufficient skilled resources, effective programme management, controlled release of units and robust railway safety arrangements, including incident reporting, investigation and prevention of recurrence.
