法國呢款列車係咪被法國放棄唔用???

冇噤過鐘何來彈鐘？
AGV Alstorm自己整畀意大利NTV，未有雙層；SNCF想繼續要動力集中，所以出 Avelia Horizon

In some cases, he says it is likely that technologies used for the past 30 years will be retained because they remain the most suitable solution. In others it is conceivable that the train will adopt technologies pioneered in Alstom’s previous high-speed offerings such as AGV and Pendolino, or even Speedelia, the concept developed for an Italian high-speed tender, which Bombardier and AnsaldoBreda (now Hitachi Rail Italy) won in 2010.

Tessier adds that while Avelia is its next-generation train, these earlier platforms are not necessarily defunct in their own right, and depending on the contract, they might still be offered.

“When you look at the market and the contracts that have been won for high-speed and very high-speed around the world – in Spain, with Amtrak, and in Saudi Arabia – they were all push-pull configurations,” Tessier says. “There is a market for different configurations, but for AGV we will see. We have not been in a position to offer this train very often.”

“We have used a lot of our experience with locomotives to dramatically reduce the cost of the power cars,” Tessier reveals. “We have moved from having a lateral corridor within the power cars to a central corridor, and the traction equipment is a lot smaller and a lot quieter than in today’s power cars. The traction system for Avelia Horizon is much closer to what we have on our locomotives, which means it will perform better and be more efficient than on the trains we have today. We are using an evolution of power electronics and an IGBT traction system to ensure it is up-to-date. We already have permanent magnet motors on AGV, and investigated whether to use them on Avelia Horizon, but we decided in the end not to do so.”

哦...
AGV性能上同新幹線/ICE相比都係差唔多?

講幾句技術先：
> 新幹線
Fastech 360Z 試過PMSM，暫時高速鐵路主流重係 induction motor，N700S冇變
PMSM個永磁會阻到檢測同保養
> ICE
啱啱InnoTrans 2018 showcase Velaro Novo 先有PMSM

E331動力分散用晒 Jacobs bogie 同PMSM，眾所鳩知前者同個下場有關
