On February 13, 2008, the Wall Street Journal published a fascinating story on a largely unnoticed revolution going on in American transportation. American railroads are, for the first time in a century, making massive new investments in their infrastructure. Better yet, not one dime of the $10 billion (with $12 billion more planned) is coming from public coffers. From the story:
For the first time in nearly a century, railroads are making large investments in their networks -- adding sets of tracks, straightening curves that force engines to slow and expanding tunnels for bigger trains. Their campaign is altering the corridors of American commerce, more so than any other development since interstate highways spread to the interior.
The story goes on to say that this burst of new private development of railroads has been driven by a massive burst of finished consumer goods coming in from Asia. These goods add to the usual cargo that freight rail carries, such as coal, grain, and chemicals. Compare all of this to the slovenly inefficiencies of Amtrack or light rail inner city transit. Moving goods is cheap. Moving people - at least in the economically affluent part of the world - is expensive.
This development, the story goes on to say, is generating development along the pathway of the railroads, but the development is primarily commercial in nature. Also, the railroads and freight trucks complement each other, where trucking companies find that sometimes they can ship goods long haul over rail rather than doing it over the Interstates.
And speaking of the Interstates, I was reading a story in this weeks' issue of The Economist of China's massive spending on transportation projects. The print edition carries a side story on the effects that America's Interstate Highway system had on productivity while it was being built. The Interstates were initially estimated to take 12 years to build at a cost of $25 billion. At the end, it took 37 years and cost (in 2006 dollars) $425 billion.
Question: Was it worth it? According to Ishaq Nadiri and Theo Manuneas, yes it was. America went through its greatest and most long lasting economic boom during its history after WWII and the Interstates had quite a bit to do with raising that productivity and making America a vastly wealthier country. Broadly speaking, Nadiri and Manuneas say that the greatest gains were reaped early on in the program and declined slowly as time went forward. The gains of the late 1950's were 31 percent of America's economic productivity growth, 25 percent by the late 1960's, and down to 7 percent by the late 1980's as more money was spent on road maintenance. One out of every five dollars was also being siphoned away from road building to build rail transit and bike paths. Freight costs in 32 of 35 industries dropped by an average of 24 cents for every dollar spent on the system.
Could something similar to the Interstates been done privately? The Interstates had incorporated into them some 14,000 miles of toll roads, mostly in the Northeast. Conceivably, a far seeing Governor and Legislature in some states could have launched state wide initiatives using toll roads, but it would have taken multi state cooperation to achieve a similar result to the Interstates. As it is, now that the Interstate system is complete, I wonder whether it would not be such a bad thing to turn most of it over to the states and either curb or shutdown collection of the federal gasoline tax the way that the Republican Congress of 1994 wanted to do? Entertaining ideas.
