Engineering Services


We provide the complete array of engineering services to address railway design and operational issues. Our expert team of in-house engineers and on-call associates provides positive solutions with speed and agility.

Project Engineering and Management

We give you the flexibility to manage your engineering project workload and respond to emerging tasks whilst maintaining your staffing policies and levels. Our engineers work within the engineering and project management teams of rolling stock manufacturers, UK train operators and ROSCOs, component OEMs as well as overseas operators and suppliers.

Mechanical, Electrical and Software Engineering Projects

We cover all disciplines including mechanical, electrical and software engineering on new and legacy rolling stock and engineering projects. These range from turnkey projects delivering a complete solution, providing a team to achieve a specific deliverable or working as part of a larger project team.

Feasibility Studies

We have considerable experience in carrying out feasibility studies on proposed changes or innovations. Our approach is tailored to meet your specific requirements.

Full services

Due to their nature feasibility study details are commercially sensitive so no specific reference projects are listed. However, we can help with studies for all types of rolling stock and infrastructure.

Railway Systems Engineering

Systems engineering integrates the multiple engineering disciplines required to deliver a modern railway engineering project. In our experience, complex projects require logical approaches to ensure that the delivered system provides all – and only – the desired outcomes.

We define a clear and concise set of system requirements needs from the outset, whilst identifying a clear focus on roles and responsibilities. These are rigorously applied through a defined life-cycle to ensure ownership is known and traceability guaranteed from input to result. Our skills in managing the complex interconnections of the various system elements ensures we successfully integrate the contributions from multiple and varied disciplines.

EN 50126 V life-cycle and bespoke project life-cycle structures

In every AEGIS project, requirements are succinctly defined and devolved to the sub-system levels with traceability both to the input requirement and to the validation activity that proves it has been implemented.

Whether following the tried and tested V life-cycle of EN 50126 or any one of the numerous bespoke project life-cycle structures, we ensure the developed system fulfils its defined requirements at each level of the cycle.

Traction Systems

Our team of specialist traction engineers is second to none in the UK rail industry. Originating from a background of traction system design, from the days of GTO thyristors through to the latest IGBT drives, our engineers have been responsible for the design and development of all aspects of traction drives – system design, performance, inverter control, power electronics, traction motor and power module design, cooling, EMC and safety cases.

This deep knowledge supports our involvement in preparing the safety justifications for many new build and refurbishment traction projects, as well the introduction of regenerative braking to existing fleets, through a sound understanding of the compatibility and safety requirements that must be met to allow safe integration of the new or modified rolling stock and the railway infrastructure.

Our range of skills in traction covers:

Structural Engineering

We deliver a wide range of structural assessments for railway applications.

Finite Element Analysis Method – FEA

We apply the Finite Element Analysis method to provide accurate numerical solutions to engineering problems. Whether an engineering system validation against the applicable rail standards or European Norms (GM/RT2100, BS EN 12663 and BS EN 13749), a system performance enhancement or failure investigation, we have the experience and expertise to support you at all levels to achieve your targets.

The analysis typically looks in detail at the stress distribution (Von Mises stress for material proof assessments or Principal Stress for fatigue life calculation) whilst ensuring that the bolted, brazed and welded joints have sufficient strength to resist the operation conditions of the system.

Working at the heart of many railway projects, we offer structural engineering support and consultancy to rolling stock providers and OEMs worldwide. We have built a reputation amongst our clients for delivering detailed and thorough structural assessments of challenging engineering designs.
