Rail

Rail vehicles, infrastructure and logistics are rapidly growing sectors for our safety and reliability services, where we provide RAMS and FRACAS solutions. This complements our long standing involvement with both structural mechanics and geotechnical simulation.

Software and Consulting

Safe and reliable delivery of rail transportation services by our clients to the public requires careful consideration, from choosing the right suppliers and equipment to determining the most efficient routes and schedules.

Our reliability software tool kit, ReliaSoft is employed in a number of ways, including:

  • Improving maintenance programs by optimising actions, spare part pools and crew policies.
  • Determining the reliability and availability of the system, resulting in reduced operating costs and minimized unscheduled downtime.
  • Implementing a FRACAS system to capture field data, assist with problem resolution and drive improvements in future designs.
  • Using advanced statistical methods to support management in financial decision planning.

Overall, ReliaSoft helps combine all information related to reliability into a single platform so that it can all be used during all phases of life, from design to field use.

Together with our technical safety experience, we provide Reliability, Availability, Maintainability & Safety (RAMS) software and consulting solutions in line with BS EN 50126. We are familiar with BS EN 50128 / 50129 for safety related electronic systems for signalling. Recent projects include RAMS analysis and accelerated life testing on an LED based training signalling system and similar assessment work for a train derailer safety system.

Our FEA experience ranges from weight minimisation studies on rolling stock to the assessment of rail connectors and gantries. We also provide Ansys software, training and technical support services to a number of rail clients, including fatigue and composite material capabilities.

We have undertaken 3D fluid dynamics studies to tackle maintenance issues and have the capabilities to investigate HVAC, electronics thermal management and exterior aerodynamic issues.

In recent years, our PLAXIS geotechnical FEA software has been used widely for rail construction and maintenance projects, accurately modelling complex soil behaviour. In particularly, tunnelling design and validation, including adjacent foundations, was undertaken by clients for Crossrail.

Non-linear material models have also been used during the study of train component manufacture. One project involved investigating the causes of  product distortion, considering placement and stacking of training wheels during final air cooling of a multi-stage forging and heat treatment process.

Clients

We have worked with a number of rail design, infrastructure and related companies, including:

Atkins | Balfour Beatty Rail | DB Schenker Rail (UK) | ESG Rail | Network Rail
Rail Pro | Transport for London | Tube Lines | Vossloh Kiepe UK | Zonegreen

This was a unique project for the client and for us. We required Wilde’s help and are very happy with the outcome. Wilde’s engineers also provided us with knowledgeable advice and recommendations to improve our design work; there have been no issues with the fabrication and installation and we have found Wilde’s engineers very helpful throughout our design development and the client’s approval process.

BCS Design

Fantastic support - I have contacted a few times and have always had the problem solved. Professional, friendly and reliable service! The engineer I dealt with has been of great help!

Monition Ltd

Overall a good course pitched at a good level.

DB Cargo UK Ltd

This course provided an excellent link between understanding soil and FE modelling in Plaxis. It demonstrated (via example) how a knowledge of soil behaviour with sensible data input produces reliable visualisation of construction.

Transport for London

With ANSYS SpaceClaim DirectModeler’s intuitive and easy-to-use capabilities, we have been able to obtain a great speed up in our process. ANSYS SpaceClaim DirectModeler has enabled us to move to Workbench and been a massive help.

ESG Rail

We relied on Wilde’s expertise to clearly define the objectives and scope of work for this RAMS GAP Analysis project and they did a very good job to help us.

Zonegreen

The work completed by Wilde has been invaluable in enabling us to design and build an optimised solution for clearing ice and snow with gusto. The computer modelling and subsequent report was very thorough offering options for alternative design.
