Avelia Horizon (TGV-M) est arrivé à Velim en république tchèque / 次世代型TGV アヴェリア・ホライズンがチェコに到着 

Oui effectivement pour l'instant il le test après il sera complet

仰る通りで、機関車の全長を短縮することで客車の定員を増やすというコンセプトだそうです。機関車単体で見ると不格好ですが、編成で見ると角度によってはまあまあという個人的な印象でした。

Yes, there is one more passenger carriage compared to the current tgv duplex.

This is Japanese, not Chinese so I think you can read with translation soft if you set it to Japanese.

It’s Japanese, not Chinese. A totally different language, it is like saying Russian is English 😅.

because the engine is not at the same place on each train

Simply because this train is equiped with all sort of testing tools and sensors that are nor standard for commercial trains. This one came her just for test on the "mach loop". I guess all those tests and measures are already terminated and I hope that tis train passed every test with a OK and it should be close to certification. This train does not lok out dated, it's more than au to date. Shinkansen is Shinkansen and TGV is TGV ; both are usefull, and both have old fashoned elements, first TGV are currently scrapped. This "outdated" train is the fastest train in the world (record speed 575 Km/h). Maglev is not a train, it's maglev a different product with another track system.

Out-dated? 😂😅 it looks really advanced. Remember that TGV is one of the fastest trains in the world. This new generation of TGV is a great product of cutting-edge technology and engineering, definitely not a product from the past.

I don’t understand why you have drawn to this conclusion? totally biased… it’s a brand new generation of TGV, and the older generation TGV duplex has the world record of the fastest train in the world. Neither of them looks out-dated compared to Shinkansen trains.
