    I like trains and I’m not American. You brought up energy density as the factor preventing long haul. Please don’t appeal to authority as the argument but rather state what you think the energy density needs to be and why to make electric long haul viable.

      The specific energy of batteries are currently an order of magnitude less than diesel. This is not a problem that is going to be solved by a slightly improved battery. The weight of batteries needed to carry long haul cargo makes it a non-starter.

        This is also true for cars, but electric cars are viable even though its the same comparison between energy density. Would you be willing to have this conversation with actual calculations and specified arguments regarding the numbers?
