The rail industry is moving faster than ever, and efficiency is no longer just a goal; it is a mandate. To meet the demands of tomorrow, operators and manufacturers must look beyond traditional building blocks. It is time to step up your rail game with Diab’s cutting-edge lightweight solutions.

The Foundation of the Next-Generation Interiors

For decades, the rail sector relied on heavy materials like plywood for interiors and flooring. While functional, these traditional materials come with heavy penalties: excess weight, susceptibility to rot and higher fuel consumption. Diab offers a definitive alternative. By switching to our advanced core materials, you can revolutionise your rail applications, from roof to floor.

The Definitive Solution for Flooring

The floor system is the backbone of the passenger experience, requiring immense durability and safety. Diab’s Divinycell PR is a 100% recyclable PET sandwich core engineered specifically to replace heavy plywood. It provides a robust, lightweight foundation that drives down vehicle weight, directly translating to lower energy consumption and reduced CO₂ emissions.

Choose between aluminium skins or fibre-reinforced skins – the latter being our most lightweight version. Full composites are often the only way to meet the very low target weights of around 6.5kg/m² that many operators strive for.

Unlike wood-based alternatives, Divinycell PR is non-organic and rot-free, ensuring long-term durability and minimal maintenance costs even in challenging environments.

Why Switch to a Diab Sandwich Core?

Transitioning to our thermoplastic core materials allows you to achieve significant performance gains without compromise:

• Step up sustainability: Utilise a circular solution based on post-consumer and post-industrial PET that is 100% recyclable.
• Step up safety: Rest assured with fully compliant materials that meet stringent EN45545-2 fire safety standards.
• Step up efficiency: Minimise weight to increase payload capacity and extend range.
• Step up comfort: Experience unparalleled thermal and acoustic insulation for a quieter, more comfortable journey.
