## Summary

The procurement process centres around the direct award of a Train Services Agreement for Class 444/450 rolling stock by SOUTH WESTERN RAILWAY LIMITED, a public undertaking located in London. This contract involves train maintenance services including the supply of spares and consumables for 45 Class 444 and 127 Class 450 units. The agreement was signed on 25th May 2025 and will run until 25th May 2030. There is an initial contract amendment notice published on 22nd August 2025. The contract was directly awarded to Siemens Mobility Limited due to technical reasons, specifically their capacity to meet operational performance and spares availability needs. The procurement falls under the utilities special regime, and the process was concluded with the direct award method.

This tender presents substantial opportunities for businesses involved in the maintenance and service provision for rolling stock, particularly those with expertise in railway and tramway locomotives. While Siemens Mobility Limited was chosen for this contract due to their unique capabilities, businesses specialising in railway maintenance services could explore sub-contracting opportunities or prepare for future tenders by understanding the technical competencies required. Organisations with the potential to offer innovative maintenance solutions, or those capable of meeting the comprehensive service needs outlined in the award, such as operational performance enhancements and cyber security implementations, could benefit from a future engagement in similar procurement processes.

## Notice

Direct award of a 5 year contract (Train Services Agreement) for the provision of train maintenance services in relation to the contracting authority's fleet of 45 x 5 car units of Class 444 rolling stock and 127 x 4 car units of Class 450 rolling stock . The service provider will also be the supplier of all spares and consumables required for the maintenance of the fleet. The Train Services Agreement also contains a right to transfer or sub-let the contract to certain third parties and an obligation for the service provider to enter into a direct agreement with the Secretary of State in parallel to the Train Services Agreement. The direct agreement permits the Secretary of State to call for a New Contract in the event of the termination or expiry of the contracting authority's services agreement with the Secretary of State. The duration of the New Contract would typically be up to 3 years and the terms of the New Contract and the circumstances in which the direct agreement can be relied upon are all unambiguously set out in the direct agreement. The Train Services Agreement also contains mechanisms under which additional services can be requested in the circumstances prescribed in the TSA and can be modified to deal with a change in law, a change to the Page 2 to 6 relevant consent or a change in the Operator's Safety Management System as well as to require the implementation of certain cyber security measures ("the Change Provisions"). In the event that the contract is transferred or sub-let to a third party, a direct agreement is relied upon by the Secretary of State or any of the Change Provisions are engaged, it is considered that these would be permitted modifications provided for in the contract."

### Procurement Information

No service provider other than Siemens Mobility Limited is likely to be able to meet the required obligations relating to operational performance, spares availability, design authority and obsolescence that the contracting authority needs from this Train Services Agreement for the necessary contract duration to meet its public passenger rail transport obligations. There is therefore an absence of competition for technical reasons and there are no reasonable alternatives to the services provided by Siemens Mobility Limited.
