Trains are undergoing a lightening process similar to the one that has already taken place in aeronautics. Loson is therefore able to transfer all the lessons learned in its aerospace skills to this field. So, the designs were reviewed to identify new construction solutions and materials. The goal was to significantly reduce weight while maintaining at least the same absorption performance as steel components.

Starting with trains for the Honolulu and Thessaloniki subways and ending with the M4 in Milan, Loson redesigned the shock absorbers for the head and tail cars, making them from carbon fiber. Given the presence of metal flanges, we integrated fiberglass inserts with insulation function.
The new buffers successfully passed crash tests with a weight reduction of 60 percent. This allowed installation by a single operator, which has a significant impact on cost and work safety.
