To compare capacity, this is only about 22 freight trains per day. (assuming 100 cars per train)

Why are we doing this again? Trains are way more versatile. We can switch trains onto tracks that go all over the place, not just where we have rivers.

Trains can't cross the ocean, but barges don't either. Trains do however carry containerized freight, which is easily loaded into container ships. This is another win for trains.
