Specialist rail consultancy services


Our vast engineering experience covers rail projects involving structures such as bridges, buildings, culverts, retaining walls, gantries and ancillary structures. We design new structures and are experienced in examination, assessment, reporting and designing repairs to existing structures.

We use our knowledge of structural failure and deterioration to design effective solutions to complex and challenging situations. We use the same knowledge during the design of new structures to ensure designs are economical and result in high performing assets with longevity.

Stations & buildings

Sweco has been carrying out consultancy works at stations for a great many years, both for Network Rail and Train Operating Companies (TOCs). Our engineers adapt their knowledge to multiple situations, materials and challenges to produce sustainable results for our clients. We understand that stations are part of the public image for the railway and that the needs of passengers and other customers are paramount at these important revenue-earning sites


Sweco is widely recognised as providing a pragmatic and fresh approach to infrastructure design. We understand the critical role that infrastructure assets play in people’s lives. Our diverse range of services enables us to offer a comprehensive package, from project inception through to construction and then asset management.

We use the latest design and analysis software and where appropriate, as well as BIM, Zero Drawing and Parametric platforms, to develop efficient analyses and designs, with
various memberships and certifications in the UK and internationally that keep us ‘on the curve’. We collaborate with all stakeholders and are conversant in working effectively with third parties such as the Environment Agency, highway authorities, local authorities and statutory sewerage undertakers.


Our aim is to deliver infrastructure designs that are economical, innovative and safe to construct and use, and sustainable. We use expertise throughout Sweco to achieve these aims. We have rail experience in depots, drainage, freight handling facilities, roads, marine works, scour mitigation, stations and undertrack crossings (UTX).

Our ethos is to maintain a sustainable environment together with social and economic considerations, and we always consider the site constraints through every aspect of a project. We understand the complex relationship between the built and natural environment and we have the environmental expertise required to influence the development of infrastructure in the future.

Environmental considerations are taken into account from pre-planning to construction and commissioning, we aim to minimise the impact on the environment and protect our precious resources. We provide cost effective remedial solutions for contaminated land sites to reducing the amount of waste to landfill through our knowledge of the sustainable reuse of materials, we have the experience to overcome challenging conditions.

Our specialist services also cover the fields of ecology, air quality, asbestos management, geotechnics, acoustics, contaminated land and remediation amongst many others, to offer a joined up approach to sustainable development.

Accountable project leadership

Our rail infrastructure team is led by hands-on directors and senior management, who play an active part in leading projects through to completion.

We combine unrivalled engineering expertise and technical knowhow with clear communication and a collaborative approach. We believe that any design proposal should be the result of a holistic analysis of all the issues and concerns that may arise across a project’s lifecycle.

We believe in building lasting relationships and delivering a tailored service that best meets the needs of our clients. We have an excellent understanding of the challenges involved in delivering work within the constraints posed by the operational railway
