The weight of the wheel frame made of carbon fiber composite material is cut in half

Spanish rolling stock manufacturer Talgo will use carbon fiber reinforced plastic (CFRP) for the wheel frames of the Avril high-speed train in the future. Compared to components of previous steel designs, the weight can be halved while maintaining the same mechanical load capacity and safety. Lightweight reduces the overall weight of empty trains, which reduces energy consumption and increases the number of passengers carried per train. The European Union has supported the development as part of the Shift2Rail initiative.
