That's more likely for TGV Est because of the tracks that are much straighter. Same for upcoming sections of TGV Atlantique...

Anyway this train was not designed for French needs specifically. It is the first time it is developped without a command from the SNCF. In fact it's called AGV because TGV is a trademark from the SNCF.
Also the recent needs of SNCF were more double deckers TGVs (duplex) to increase capacity on SE line, the AGVs is a little topic in the French network for today's needs.

IMO it would be better only to use automatic speed selection, so that the train always accelerates and brakes as much as it can without people and coffecups tilting.,

wasn't this also an conceptual design for this train?:

I'm not entirely sure, I though the drivers could just set a speed. On having a search round the web I can't find any exact descriptions. There is certainly a automatic braking control during emergency braking to ensure safety.

that's right ... SNCF actualy is trying to INCREASE the "Duplex" capacity by removing the middle powercars (duplex run in double units)


They have plans to motorize de bogies in the extremities of the coach set (to maintain the same power/weithg ratio) and increase each train from 2x8 to 2x9 coaches ... in the process they will gain some 64 "free" powercars (one of each set will became available).

Basicaly they will became like Eurostar stock with double set's of 1 power car and 9 coaches each ... wich means some 10% more capacity in each set (Comparing to today) and already more power units to add new cars and make some 32 other sets of Duplex (?).

I saw this proposal too. I'm not sure how they're going to get the same power to weight ratio, does anyone have any ideas? They could power the axles in the end trailers, but would that mean the remaining loco in each half-set would have to take on twice as much transforming/electrical conversion as it did before? If so I'm sure the remaining loco would have to be modified as well. I'm sure it can be done, would just like to know how!!!

The end and middle bogies of the rake would be powered bogies, giving the same power/weight as if a loco was used. On a normal length train, the front loco is powered from the pantograph at the back. On this proposal, both pantographs would be used and would feed bus power to the train. The same shrinking in transformers / power components that allows the AGV to be built would enable conversion of the supply from 25kV to the 4 intermediate power bogies. These would be housed in the area over the bogies that you can see in the diagram above.

It is interesting that it looks nothing like the previous prototype - which I think looks better.



Although I think the new one looks better outside in this shot.

Is there any information on the power supply requirements of the new train?

Also, is it possible to run a high speed train on overhead lines until on board batteries are charged by using alternators which could run the train whilst in country areas thus reducing support structure costs. Once back in city areas they could be run on overhead lines. The reason I ask is because here in Australia these costs are one of the reasons we do not have high speed trains.

There's no way really a battery could hold enough power to operate the train for more than a very short distance, I think it would be unviable.

At first sight I thought the train looked ugly but the more I watch it the more I like it...
I suspect that when in motion it will look awesome...
Funny news:SNCF is said not to be eager not to buy it because they focus on maximum passenger capacity so they might go for duplex TGV but...Air France KLM-certainly pissed off to lose market shares to HST-are rumoured to move into rail travel...and buy the AGV!!!

Currently the UK is tendering for a replacement for the HST which will be able to use both 25kV where it is available and diesel engines where it is not. This is called the Intercity Express Programme. It will be a kind of hybrid EMU / DMU.

The original HST is what you Aussies bought from us Poms and called the XPT. Perhaps you would like to join in and purchase some of these new models too?

Now I got it!!


When I first saw this picture;



It reminded me of something but I wasn't able to put my finger on it until I saw an old revival movie.



It's Mosra in it's larval state.

Sorry but I can't really see the resemblance...
Not more at least than an ICE3 would resemble it...
