6. Conclusions

The weight reduction and optimization of railway vehicles have several positive effects including
energy savings, increase payload capacity and reduction of rail damage.
However in order to maintain the performance of the current carbodies regarding comfort some
extra cautions should be taken.
A study in detail like done in AVRIL train is necessary to avoid discomfort for the passenger at
high speed. FEM calculation together with Multibody simulation are powerful tool for design
phases. Prototypes to assess the hypothesis employed are very useful to measure and obtain
real mode shapes and Eigen frequencies to compare with the track excitation.
