## Summary

The procurement process for the "Class 158 Rolling Stock Lease" is being managed by ScotRail Trains Limited, a railway services provider based in Glasgow, United Kingdom. This procurement concerns the leasing of railway and tramway locomotives and rolling stock, specifically the Class 158 vehicles. The process has been updated as of 22 May 2026 with modifications to an existing lease that aims to secure ongoing operation while new rolling stock solutions are procured. The leasing period originally began on 1 April 2022 and is now scheduled to expire on 31 March 2030, with a three-year extension and an additional two-year extension option. The procurement stage is at the contract update phase. Contracts have been awarded to Porterbrook, and the legal basis follows the CELEX scheme, specifically regulation 86(1)(b) for modifications within the Utilities Contracts (Scotland) Regulations 2016. The total value of the lease is significantly impacted by necessary extensions, reflecting annual inflationary increases.

This tender presents substantial opportunities for businesses involved in railway manufacturing and maintenance, especially those experienced with rolling stock that can integrate with Scotland's unique rail infrastructure. Suppliers specialising in innovative rail technologies, such as battery-powered and network-electrified solutions, may find future opportunities as ScotRail embarks on its full procurement process for an enduring rolling stock solution. Firms involved in diesel train refurbishments are particularly well-positioned due to the need for interim diesel operations. The procurement method chosen is limited, allowing strategic engagement opportunities for businesses with specific technical expertise in railway vehicles, maintaining technical compatibility, and ensuring efficiency in safety and operational requirements stipulated by Scottish Ministers.

## Notice

This notice concerns a modification to an existing lease (the Lease) procured whilst ScotRail was under the Abellio franchise ownership, between ScotRail Trains Limited (SRT) and Porterbrook Leasing Company Limited (Porterbrook) for 80 Class 158 vehicles (the Fleet). The Lease is currently scheduled to expire on 31 March 2030 and a 3-year extension has been agreed to the Lease for the same scope of supplies, with an additional option to extend for up to a further 2 years. The value of that extension (inclusive of options) is GBP 73,300,000 excluding VAT. This extension is necessary to ensure SRT is able to discharge its obligations and continue to deliver vital services while the suburban and rural new fleet procurements are commenced and is therefore an interim solution until the new fleet can be procured, built and commissioned for passenger service. An interior refurbishment will be undertaken to the Fleet to ensure it can continue to operate for passenger service for the duration of the extension.

### Lot Information

Lot 1

The Lease is being modified in accordance with regulation 86(1)(b) of the Utilities Contracts (Scotland) Regulations 2016 as additional supplies not included within the original procurement have become necessary, and a change of contractor cannot be made for economic or technical reasons and would cause significant inconvenience or substantial duplication of cost for SRT, because: 1. The modification has become necessary: there is a need to secure the ongoing operation of the Lease, which includes lifeline services in rural areas, while SRT carries out a full procurement for an enduring rolling stock solution using emerging technologies (including batteries and network electrification). Diesel trains are the only feasible option for this interim period. 2. A change of contractor cannot be made for economic or technical reasons: this is because: a. the Fleet has specific characteristics and technical features that are designed to interoperate with the rail infrastructure and SRT's other fleets and are required for operation on the West Highland and Stranraer Lines, as well as Glasgow suburban routes. For example: i. the Fleet is the only available DMU passenger stock which is fully accepted for operation on the West Highland and Stranraer lines and is able to make use of differential speed limits in order to meet the journey times of the timetable; ii. any alternative Fleet would require an extensive programme of train crew and engineering staff training, which would create significant additional (and disproportionate) training workload at a time when SRT is already engaged in an intensive programme of recruitment for future fleet cascades and new trains; iii. a Section 54 agreement has been agreed in relation to the Fleet. b. SRT's analysis has confirmed that there are no alternative available fleets that contain the necessary technical features and could meet these requirements. 3. In the event that an alternative existing fleet with suitable performance and technical characteristics was available (which in SRT's view is not the case), and that fleet could be adapted to accommodate the necessary technical features, this would result in substantial duplication of cost, significant inconvenience and extra time out of service, which would be disproportionate in the context of an interim solution

Options: As per II.1.4, there is an option to extend for up to a further 2 years.
