Re:Magnets versus Wheels (Score 1)

SCNF typically operates TGV North line (Paris-Lille) [1] with two connected single-deck TGVs, to double capacity. As the limiting operational factor is the distance between trains, the more passengers the better. Anyway, I have got to believe that the two locomotives of each halves are running, hence there should be traction from the middle of the train. [1] not always, and probably not only on that one, but that's the one I know :)
