London Underground’s District Line trains launched the first production trains fitted with lightweight aluminium composite honeycomb doors in 1978. Several decades after this first step, what are the advantages of using composite materials today?
Need for weight reduction in rail vehicles
Increasing passenger demands, including universal access toilets, CET tanks, power outlets, air conditioning, tables, tipping mechanisms, improved crash structures and crumple zones, are making trains increasingly heavy. Body, external doors, bogies, couplers, driver’s cab, interior linings, doors and all passenger interiors are key areas for weight reduction using composites
