AEROACOUSTIC EVALUATION
10
– Weight reduction ( g.e : bodyshell stucture in Alu Light Alloy and Composite)
– Aerodynamic performance– Traction Equipment Efficiency
ENERGY CONSUMPTION
But also Train Configuration
Articulated Train vs. Conventional Train
– Overall weight reduction: more than 10% weigth reduction (Less Traction Power installed for the same specific power and for the same train length)
– Aerodinamic drag optimisation : less bogies for the same train length.
