Rail Surveying
Safeguarding the UK’s rail infrastructure
Rail surveying is central to the upkeep and expansion of the UK’s rail network, supporting both the ongoing modernization of infrastructure and the safety of millions of passengers. With the growing demand for reliable public transport, rail operators and infrastructure teams face the challenge of upgrading and maintaining tracks, tunnels, and stations across the country.
Precision surveying is essential to these efforts, providing the data needed to ensure that rail projects are executed efficiently, safely, and to exacting standards. From aligning new track to monitoring wear on existing routes, accurate surveying underpins the smooth operation of the UK’s railways.
To meet the unique demands of rail projects, SEP offers specialised surveying equipment designed for the complexities of rail environments. Our range includes high-precision total stations, GNSS/GPS systems and laser scanners that enable surveyors to capture data accurately in diverse conditions.
Whether it’s for initial planning, construction, or regular maintenance, our technology equips rail professionals to enhance project efficiency, improve safety, and ensure that the UK’s rail infrastructure meets the needs of the future.
