TRB Lightweight Structures Ltd.
Making An Impact Where Weight Drives PerformanceTRB Lightweight Structures is a Tier 1 supplier to the UK and European train builders, providing high-quality, lightweight solutions.
This includes passenger doors, detrainment doors, composite door leaves, catering modules, bike storage areas, universal access toilet modules, structural partitions, train manager offices and magazine racks.
All solutions are supplied fully assembled, featuring components such as doors, glazing, lights and electrical sockets.
Fully equipped products made with composite materials
TRB provides cost-effective products that often outperform the original components. The company supplies a complete, fully equipped product, which is painted in its in-house facility and supplied ready-to-fit into the vehicle. Damaged items are handled in the same manner, reducing out-of-service times and costly delays.
TRB uses composite pre-impregnated fabrics such as Carbon, Kevlar and Glass fibres in a wide range of woven and unidirectional formats. Each fibre style can be impregnated with either Epoxy or Phenolic resins as well as our new Green alternative Bio-resin.
TRB has strong relationships with prepreg manufacturers and a number of its sandwich panels are produced with proprietary pre-impregnated resin systems, which were developed specifically for the company. TRB uses an autoclave, vacuum-bag oven and press-moulding processes to cure fibre-reinforced plastic (FRP) panels and components.
Rolling stock refurbishment and reverse engineering
Refurbishment of current rolling stock is often a cost-effective solution, even if original design documentation has been lost.
TRB reverse-engineers physical parts by using a Faro CMM or Creaform Handyscan 700, which interfaces with the company's 3D modelling package. This lets TRB accurately produce 3D drawings whose originals do not exist or are incomplete.
Once the component's external dimensions have been recorded, the product is cautiously stripped-down and each individual part measured in order for it to be redrawn.
Composite Door Leaves - The Next Generation
TRB has developed a new biocomposite resin based carbon fibre reinforced (CFRP) sandwich panel door leaf with a 100% recycled foam core. This new biocomposite door leaf product has been specifically designed and fire rated for both overground and underground rail use; the composite structural system easily passes BS 6853 and BS 476 Part 7 Class 1a and is EN 45545 HL3 compliant.
TRB can now offer the rail industry a sustainable, ‘green’ composite material option for carriage door leaves at a comparable cost to aluminium bonded door leaves, with a 35% weight saving. This has been achieved by TRB applying its in-house understanding of composite materials technology and expertise to railway applications, broadening its product offering to its established rail industry customer base to meet a growing global market need to use greener, more energy-efficient products.
Interior, exterior, detrainment, egress and cab security rail doors
TRB designs, builds, paints and assembles the operating mechanism, as well as installs a wide variety of doors, ranging from simple hinge doors to complex, plug-slide doors and fold-out steps. In-house test rigs can accommodate all types of testing from load tests to simulated evacuation tests.
IRIS approved, TRB have been manufacturing high-quality rail doors and rail interior products for over 60 years. Since formation in 1952, TRB has grown into a leading international manufacturing and engineering company supplying the rail industry.
TRB offers a concept to delivery service, which includes design, build, test and validation of products. Our knowledge of the rail industry standards and requirements ensures a smooth development and approval process. TRB has extensive experience with both new train builds and refurbishment of existing trains.
