Trains are far more efficient, less subsidized, safer, less polluting...

Even if you electrify trucks the tire and brake wear and road degradation contribute an enormous amount of PM 2.5.

Sure you'll need trucks for the last mile but every ton of freight we can move to rails or waterways is a victory for humanity.

I used to think that too, but

- economically trains are a monopoly. This point dwarfs all others.

- we don't have two-directional rails everywhere

- electric trucks can change the economics and mitigate the pollution of trucking

Electric trucks will still emit a rather large amount of pm2.5, and are still heavily dependent on both direct and indirect federal subsidies.
