## Summary

The procurement process for the "Class 170 Rolling Stock Lease" involves ScotRail Trains Limited as the buying organisation. The contract, which falls under the industry category of railway and tramway locomotives and rolling stock, is situated within the UK, specifically in the region of UKM. The procurement is in the award and contract update stage as of 22 May 2026. This process is executed using a limited procurement method without prior publication of a call for competition. A significant component of this lease is the modification to extend the contract, originally scheduled to end on 31 March 2030, by an additional ten years with an option to extend for a further two years, reaching a total potential value of £421,700,000.

This tender opens substantial avenues for businesses specialising in railway and rolling stock services to engage with ScotRail in supplying or servicing rolling stock designed for the east suburban and rural routes. Companies with expertise in cutting-edge railway technologies, such as network electrification or battery technologies, might find lucrative opportunities as ScotRail seeks solutions for its ongoing rail operations. Businesses capable of delivering necessary modifications, technical support, or refurbishment services for the Class 170 fleet are well-placed to benefit. The current leases involve partnerships with prominent companies like Porterbrook, indicating potential subcontracting opportunities in areas such as engineering, refurbishment, and other technical services, particularly those based in the UK. Businesses capable of meeting these technical and operational requirements and participating in complex railway projects are well-suited to compete effectively.

## 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 102 Class 170 vehicles (the Fleet). The Lease is currently scheduled to expire on 31 March 2030 and a 10-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 265,700,000 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 and east suburban 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 East Suburban Lines. For example: i. the Fleet is the only available DMU passenger stock which is fully accepted for operation on these lines and is able to make use of differential speed limits to meet the required journey times; ii. the Fleet has been fitted with Variable Rate Sanding Equipment, funded by the Scottish Targeted Performance Fund, to offer improved braking performance in low adhesion environments and support SRT's safety case; iii. the Fleet is able to maintain technical compatibility with the network (including the CL158 fleet with which it is required to operate interchangeably) and depots, ensuring SRT satisfies the operational requirements stipulated in its Grant Agreement with Scottish Ministers. iv. any alternative Fleet would require an extensive programme of train crew and engineering staff training, incurring significant 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; v. Please note 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 (other than the CL158s that SRT already operates) that contain the necessary technical features and could meet these requirements. 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 Section II.1.4, there is an option to extend for up to a further 2 years.
