A few days ago, the Revolution VLR (Very Light Rail) project in which TRB Lightweight Structures of the United Kingdom participated has developed a brand-new passenger train, which facilitates the expansion of railway lines and the restart of old lines
.
During the project implementation, TRB worked with Transportation Design Institute International (TDI) to design the train's composite body shell and to manufacture modular, one-piece structural panels for the inner and outer walls of the car
.
The Revolution VLR project aims to develop a train structure that is lighter in weight and consumes less energy, while meeting stringent rail industry safety standards and government decarbonisation targets
.
To this end, TRB produced modular panels using carbon fiber laminates and recycled foam cores
.
The project also uses a unique polyfurfuryl alcohol (PFA) bio-resin to replace phenolic resin extracted from sugarcane refining by-products as the matrix for the composite
.
Combined with advanced technology, the modular demonstration car body produced by the project team is up to 40% lighter than the traditional train body of the same volume
.
This means that single-carriage vehicles can operate on older lines that are reactivated, or on new lines with lightweight infrastructure
.
Lyndon Newman, chief engineer of lightweight structures at TRB, said that the modular panels used not only reduced the weight of a single carriage by 16 tons, but also used sustainable biomass materials
.
This will greatly facilitate the decarbonisation of the UK transport sector
.
Paul Salkeld, Head of Design at TDI, added that the TRB team has designed lightweight, modular, and standardized train car panels for the Revolution VLR project, which not only significantly reduces the vehicle's weight, but also facilitates the replacement of parts for general maintenance requirements
.
Considering the service life of 30-40 years, this will be an important factor affecting the service life of the train
