I'm surprised they don't build the vehicles with split axles and either differential gearing or two smaller motors per (split) axle instead of one big one.
Edit to add:. I've seen the explanation videos that show why the tapers on the wheels mean that differentials aren't needed for rail vehicles, but the noise seems to tell a different story.
