actually it is not so suprising. Multimodal transportation has really be growing. The real change has been the collapse of the unions. You now have the containerization of train transport which parallels ship transport. Notice how box cars are a disappearing phenomenon.
Now we just need trucking to fully containerize and we have lower costs.

I did notice 142 boxcars all at once several years back....
