I read an article about why the American railroad were never electrified. I found it by accident while researching the GG1 locomotive.

@lubricustheslippery5028 The railroads learned long ago that lightweight engines can't pull economically profitable trains. Take a look at the legendary GG1 electric locomotive.

@peterkratoska4524 Diesel locomotives have been diesel-electric since Day One. It solved the problem of how to get the power to the wheels. Chains and belts aren't strong enough. Gears, driveshafts, and universal joints are too cumbersome. It would also require a transmission of some sort. Electric was the way to go, especially since reliable traction motors were readily available.

@moefar5400 Try to imagine modern commerce with sailboats. Heck, Americans might have to return to manufacturing their own products.
