Is the US finally getting ‘all aboard’ with electric trains?

This is a most excellent place for technology news and articles.
Europe as a whole is not a lot smaller than the US, so I think many of the same efficiencies can be achieved. China has also been able to do it very efficiently and is basically the same size as the US. Granted, they have a much larger population and more potential customers, but it can definitely be done.
As I said, lack of imagination. There is this bump in effort that has to be transposed to reach actual returns on investment because energy is too cheap and secure atm. But once that bump is transposed, there is a large landscape of gains, but they can't see past the bump.
