Revolution VLR’s composite bodyshell design

TRB has worked closely with Transport Design International since 2018 and supported the Revolution Very Light Rail project as a supplier since. TRB have been of great importance with supporting the innovative side of the project. Read the full Press Release below:

Rail vehicle revolution for tomorrow’s transport networks

TRB Lightweight Structures is delighted to be part of the team behind Revolution VLR (Very Light Rail), an innovative passenger vehicle designed to simplify extension of existing rail networks and allow the reopening of historical lines. TRB worked closely with consortium leader Transport Design International (TDI) on the vehicle’s composite bodyshell design, manufacturing the modular, one-piece structural panels that form both the inner and outer walls.

The design objectives for the Revolution VLR were to engineer a substantially lighter vehicle offering reduced energy consumption. While adhering to rigorous rail industry safety standards and governmental decarbonisation goals. TDI developed the design of the modular panels composed of moulded carbon fibre laminates with a recycled foam core. TRB’s expertise in the tooling and materials processing ensured a high quality, lightweight solution that met the design brief without compromising structural strength. The project also took advantage of a unique polyfurfuryl alcohol (PFA) bioresin – a sustainable alternative to phenolic resins derived from a byproduct of sugar cane refining. Combined with a host of other innovative technologies, this modular construction resulted in the Revolution VLR Demonstrator being 40 per cent lighter than traditional heavy rail vehicles of similar capacity. This means that the single-carriage vehicle can run on reinstated existing lines, or new routes using lighter weight track infrastructure.

“Our lightweight structural modular panels not only contributed substantially to a 16-tonne reduction in total weight, but were also obtained from a sustainable source. This will significantly contribute to government commitments to decarbonisation in transport.”

- Lydon Newman

Lead Engineer at TRB Lightweight Structures

“TRB worked hard to meet all the technical requirements producing lightweight highly toleranced body panels for the Revolution VLR’s demonstrator. This modularity allows construction of a lighter vehicle and assists in the replacement of parts for general maintenance requirements. This is a key consideration for vehicle longevity, giving a 30 to 40 year lifespan.”
