With AC motors it is a constant current, its not as high as the DC
peak, but it never tapers off, it is flat, across the whole train
speed. But at all times it is considerably higher than the DC motor
train at speed.

Although there is also the issue of DC versus RMS current. When they
developed the cross-channel cables that transfer electricity between
..uk and .fr they made a schoolboy error and forgot they were
transferring DC, with results that as far as I can tell only
electrical engineers find actually amusing.
