Then if, as you say, one train is equal to 150 semis, there's 150 jobs lost as a result. Now what? And that's provided they are all solo drivers and not team drivers.
We would discover lots more jobs for people associated with freight trains, including people from long-haul trucking who could make the switch. We would also have a good excuse to upgrade our railroad infrastructure to handle greater loads and higher speeds.

And that's a problem why? Every factory moving to slave labor nations equal thousands of jobs lost... and I'm told day in and out by free trade worshipers this is a good thing... so why is moving back to rail other than local delivery a bad thing?
