May be true, but why does transrapid accelerate so fast? To accelerate
fast you should have a) lots of power, or b) low friction/drag. If you
compare TR's data with the recordruns of TGV 325, than TR accelerates from
0 to 430 in 4 minutes, and TGV 325 needed 8 minutes from 0 to 440. Where
is the gap?
