I have a rather technical question about the V150, so its a toss up between here and the Traction forum, but I guess people who know more about TGVs are likely to hang around here so I will ask it here.
The V150 seems to have had powered bogies that contributed more to the traction power of the train than the power cars themselves, but were these powered bogies supplied from transformers carried in the power cars, in the end cars, or in the central coach in the formation?
I ask because I've been puzzling over the "TGV Grande Capacité" concept in the context of producing a ~400m TGV Duplex type formation for HS2.
I was wondering if you could just add fifteen trailers to the V150 formation, and how the location of the traction motors would have to be altered to allow this. (Ie: whether the motors have to be mounted together in the centre of the train somehow or if they could be mounted at one or both ends)
It would seem that if a modified V150 could be used as the basis of this train that development would not be very long and thus 400m trains could be used for the line without massive development costs.
This would also enable a train that would have ~1300 seats at similar to existing densities to be put into the train with only one train's worth of crew (catering, driver and guard).
Anyone have any thoughts?
