I drive I5 regularly. It's flat all the way from Canada to San Diego. The train tracks run parallel to it.

It's also jammed with semis.

There's a lot of low hanging fruit in transitioning to rail.

It doesn't have to remove every truck from I5 to be a huge win, either. Like I said, I5 is packed with trucks 24/7.
