HS2 Rail Innovation: Siemens, UK High-Speed Project Update

“`html

Introduction

HS2 is inviting small and medium-sized technology firms to submit proposals to lower costs and accelerate timelines as part of a review of the high-speed rail project. The call for entries, led by HS2 chief executive Mark Wild, is for the eighth round of its Innovation Accelerator programme, with applications accepted until 31 October 2025.

Innovation Accelerator Programme

The eighth round of HS2’s Innovation Accelerator initiative, a partnership with Connected Places Catapult, is seeking proposals from small technology firms outside the traditional rail sector. The aim is to find solutions to increase productivity and address complex challenges. From the applicants, 12 finalists will be selected, and six firms will be chosen to further develop and test their solutions in a trial project with HS2.

Project Progress and Goals

According to HS2 senior innovation manager Jon Kelly, the priority is to get HS2 “back on track.” He noted that 2025 has been a significant year for the project, with the longest bridge and longest tunnel reaching completion. The programme seeks the country’s best innovators to help achieve this goal.

Previous Results

Since 2020, the HS2 Innovation Accelerator has supported 37 small technology companies through pilot projects, resulting in over £50m in cost savings across the HS2 programme. HS2 data indicates that over 40% of participating firms have secured further work within the supply chain, collectively raising more than £240m in investment and creating over 580 new jobs.

Recent Contracts

In January 2025, Siemens Mobility secured four infrastructure and maintenance contracts for the HS2 railway project, joining other major contractors in the Rail Systems Alliance. These contracts, valued at around £560m ($689.3m), will address essential technological components for the 225km rail line connecting London and the West Midlands.

Conclusion

HS2 is currently inviting technology firms to participate in its Innovation Accelerator programme to drive down costs and expedite timelines. The program has previously yielded significant cost savings and investment within the supply chain.
