More than 4,000 miles of train tracks stretch through California, winding up the blustery Cajon Pass and snaking through the desert surrounding Barstow.
Those tracks could be seeing a lot more traffic in the next few years as trains loaded with Chinese-made toys, electronics and clothing roll eastward, connecting West Coast ports with cities across the U.S.
Warren Buffett is a believer. In November, the world's second-richest man paid $34 billion for railroad giant Burlington Northern Santa Fe Corp., despite a deep downturn in the railroad industry. Buffett characterized his investment as an "all-in wager on the economic future of the United States." But it's also a bet on globalization and the renewed importance of rail in the nation's transportation network.
Southern California is a key hub in his new empire. About 40% of all goods that the U.S. receives in containers from overseas enter the country through the seaports of Los Angeles and Long Beach. That freight must then move overland to retailers across the country.
Fort Worth-based BNSF has invested hundreds of millions of dollars in recent years to beef up its Southern California operations to grab a bigger share of that business.
"Within our 28-state network, California is incredibly important to us," BNSF Chief Executive Matthew K. Rose said. "A lot of trade comes through there, a lot gets consumed in California, and a lot gets handled and repackaged there."
China's rise has given a new push to U.S. railroads, which have chugged their way back into the nation's transportation future after losing ground for decades to the trucking industry.
The sheer volume of inbound cargo from Asia to North America -- more than 40 million container loads last year -- has made it cost-prohibitive to haul all those goods over congested U.S. highways.
Rail companies have strengthened their networks and upgraded their equipment to handle the ubiquitous metal shipping containers to provide a nearly seamless transition from cargo ship to freight train to truck or any combination in between. This so-called intermodal traffic has been the fastest-growing segment of the industry for about a decade.
In 2008, international and domestic intermodal cargo accounted for nearly a third of BNSF's revenue, a figure that's expected to grow when the U.S. economy gets back on track.
Although factory jobs have been lost to Asia, international trade is now a pillar of the Southern California economy, accounting for more than 300,000 jobs. Chains such as Wal-Mart Stores Inc. and Costco Wholesale Corp. depend on the nation's trains running on time.
"There wouldn't be big-box retail and globalization if you had to truck in all those containers -- it wouldn't be worth the cost," said Anthony Hatch, a rail consultant in New York.
Over the last 20 years, ton-miles of freight hauled by the nation's biggest railroads doubled, from 876,984 ton-miles in 1985 to 1,770,545 in 2007, according to the most recent government figures. Paul Bingham, managing director of world trade and transportation markets at research firm IHS Global Insight Inc., projects that number will grow 14% within a decade.
Environmental concerns are also helping to fuel rail's comeback. Railroads can move a ton of freight an average of 457 miles on a gallon of fuel, according to the Assn. of American Railroads.
Freight rail's resurgence has been stunning for even some of its most die-hard devotees. Pittsburgh rail entrepreneur Henry Posner III recalls the mid-1970s, when railroads were tumbling into bankruptcy after losing market share to big rigs and air freight. He credits deregulation in the 1980s, and the brutal downsizing and cost-cutting that followed, for the industry's survival.
Posner's company, Railroad Development Corp., owns a piece of what was once the famed Chicago, Rock Island and Pacific Railroad, as well as some lines in Latin America.
"Growing up, I was told that the age of the train was just around the corner, and in fact I have lived to see it," Posner said.
He said Buffett's big bet on rail was a "reflection of the position of the rail industry as an important part of our national transportation infrastructure."
One of the linchpins of this global supply chain can be found in the industrial cities of Vernon and Commerce, home to BNSF's Hobart rail yard. The massive facility, on 245 acres near the 710 Freeway, is one of the biggest operations of its kind in the world. Workers toil 24 hours a day, seven days a week, offloading shipping containers ferried by big rigs arriving straight from the ports. They pluck the uniform boxes from the backs of the 18-wheelers and stack them neatly on lines of train cars, some stretching two miles.
Other containers are offloaded directly from cargo ships to trains inside the ports.
