6. Mastering innovations
Proven solutions
Minimised technical risks, but low performance improvements
Innovations
Breakthrough in performances, but risks if development is not mastered
Speed
Capacity versus weight
Cost per seat
Flexibility
Comfort
Interoperability
Aesthetics 6

7. The Alstom response A step by step and consistent development…
Always capitalizing on feedback from previous generations
With technological continuity.
Continuous improvement of Technical & Economical Performance, Operation Flexibility, Comfort. 7

8. …but keep to constant principles
Articulated train
Bogie
Reduction of overall trainset weight
Reduction of LCC & Maintenance costs 8

9. Articulated trainset advantages
Reduction of the number of the bogies
Reduction of maintenance costs by 30%,
Reduced energy consumption by limiting aerodynamic drag and weight,
Reduced external noise generation.
Reduced vibration (noise, pressure wave,…) on board.
The articulation acts as a damper to reduce movement of one car relative to another.
Noise reduction.
Passengers do not sit on top of bogie.
Safety
In case of derailing, the train remains aligned,
Stability under cross-winds. 9 9
