Superconducting magnetic levitation is the “next generation of transportation,” says a new rail advocacy group that calls itself The Northeast Maglev (TNEM). The group’s proposed New York-Washington maglev line has received attention from the Washington Post and Baltimore Sun. TNEM’s claims might have seemed valid 80 years ago, when maglev trains were first conceived, but today maglev is just one more superexpensive technology that can’t compete with what we already have.
Maglev has all the defects of conventional high-speed rail with the added bonuses of higher costs and greater energy requirements. Unlike automobiles on roads, rails don’t go where you want to go when you want to go there. Compared with planes, even the fastest trains are slow, and modest improvements in airport security would do far more to speed travelers, at a far lower cost, than building expensive new rail infrastructure.
