We need a more efficient system for transporting goods, like railroads

The transportation system already uses railroads to transport goods. Just
because you do not see them doesn't mean they aren't there. In fact many
rail cars are designed to precisely fit the cargo holds of 18wheelers.
The train travels from the port to a distribution center and the truck
goes from distribution to the final destination.

The truck is a more recent invention than the train - I'm not sure how
regressing from a 20th century technology to a 19th century one could be
called more efficient.

What is more efficient in terms of fuel usage; driving a loaded 18 wheeler
across country or putting the trailer on a railroad train along with 100
others and transporting them across country? I don't know and am curious.

My guess is the railroad is far more efficient, fuel-wise. If it is, we
should be doing more of it. But then, we'll have a problem with employment
in the trucking industry.
