Trucks are convenient because they enable flexible point-to-point operation, but they are relatively inefficient, dirty, dangerous, and destructive to our roads. Rather than wait for some still-unrealized technological breakthrough, we could instead expand our national freight rail system. At first blush, it would be easy to believe that freight rail’s day has passed. From its peak a century ago at more than 250,000 miles, today there are fewer than 95,000 miles of track for Class I railroads, as rail lost market share for the movement of people and goods to air travel and the interstate highway system. From 1990 to 2013 alone, the US population increased 28.2 percent while track miles decreased 28.6 percent, despite increases in shipping and freight movement.
