The Draft for Public Comment (DPC) is now available for the IET's Guide to Electrical Aspects of 25 kV AC Railway Electrification.
This is your chance to provide your comments and proposals on the content to ensure that the publication truly reflects the needs of the industry.
As the UK continues to progress toward a lower‑carbon transport network, the demand for robust, well‑understood electrification standards is increasing. This guide aims to support that transition by offering a clear, structured reference covering the key electrical principles, system considerations, and best‑practice design processes that underpin modern AC railway electrification.
What the Guide Covers
The draft brings together a broad sweep of technical and practical material intended to support engineers at all levels of experience. Areas covered include:
- Core electrical principles of 25 kV AC railway electrification
- Guidance on specifying and developing system and equipment solutions
- Real‑world examples illustrating effective design and implementation
- Links to additional reference material to support deeper learning
By consolidating foundational knowledge with applied practice, the guide aims to equip both new and experienced professionals to meet future electrification challenges.
Why Your Input Matters
The DPC provides an opportunity for the railway engineering community to shape a resource that will influence future practice. Whether you work directly on electrification schemes, contribute to related disciplines, or support wider rail infrastructure programmes, your insight is valuable.
Reviewing the draft ensures the guidance is practical, relevant, and reflective of current industry needs. Contributions will help strengthen engineering practice and support the development of a skilled workforce capable of delivering future electrification programmes across the UK.
