Summary of the contracting process

ScotRail Trains Limited is actively seeking tenders for the provision of Air Reservoir overhaul services, part of a selective procurement process under the industry category of repair, maintenance, and associated services related to railways and other equipment. The project has been divided into two lots, with services required for Class 153, 156, & 158 trains and separately for HST Class 43 Power Car & Mark III Coach, with varying contract periods. The tender process follows a negotiated procedure with prior call for competition, and the deadline for submissions is 24th July 2026. Interested suppliers are encouraged to participate in this tender, which is under the region UKM, and to complete their submissions via the ScotRail e-sourcing portal, Wax Digital.

This tender presents a promising opportunity for businesses specialising in railway maintenance services, particularly those capable of delivering safety-critical overhaul solutions. Companies with experience in handling railway equipment and meeting rigorous standards, as well as those adept in resource management and asset labelling, would be well-suited to compete. Given the allowance to bid for multiple lots, suppliers with comprehensive capabilities in servicing both specified train classes will have the potential to grow significantly within the railway maintenance industry by aligning with ScotRail's strategic overhaul requirements.
