By 2010 the European Commission predicts transcontinental
freight traffic will have risen 50 percent as a result of European expansion,
and much of that will have to cross the enormous obstacle of the Alps. Right now
the only practical way for most heavy traffic to get through is by truck and
tunnel. And while that could change if safer and cleaner rail lines were opened,
the chances are that won't happen anytime soon. Several private
trucking companies have adapted quickly and creatively to the demands of
European unification. Some of the bigger truckers trace cargoes with the Global
Positioning System and sophisticated computers. And if trucks also bring more
road hazards and pollution, at present there is no alternative. Right now only 8
percent of European merchandise moves by rail, compared with more than 40
percent in the United States. Delays are so common that the average speed for
freight is about 18kin an hour. The railways have had trouble
outgrowing a heritage of national rivalries and open warfare between Europe's
countries. The result is what another European Commission report calls "a mosaic
of badly interconnected national systems." Language barriers remain a problem,
requiring crew changes at some borders. Switching systems and signals
differ. And efficiency is more of a dream than a goal. Europe's
railroads still have to deal with "phantom trains" that run so late that they
combine with others and disappear from the railroad's records. In an era when
many companies depend on a "just-in-time" inventories to make a profit,
railroads are rarely on time at all. Yet there is little
official enthusiasm for changing the system. The reality is that governments
have helped create the imbalance between road and rail in Europe—and government
action will likely be needed to fix it. The French emphasis on using rail to
move people instead of goods, for instance, has helped cripple freight service.
"All the investments went to passenger traffic," says Denis Douté, director of
freight services for the French rail company SNCF. Freight trains have had to
find "windows" to run in between passenger trains, unlike those in the United
States, which often travel on separate tracks. The further development of the
freight network requires massive investments to modernize existing
infrastructure and open new ones. However, the political will to fund that kind
of investment is lacking, which means the citizens will have to hold their noses
for a while longer.
