High-speed magnetically levitated ground transportation (maglev) is a new surface mode of transportation in which vehicles glide above their guideways, suspended, guided, and propelled by magnetic forces. Capable of traveling at speeds of 250 to 300 miles-per-hour or higher, maglev would offer an attractive and convenient alternative for travelers between large urban areas for trips of up to 600 miles. It would also help relieve current and projected air and highway congestion by substituting for short-haul air trips, thus releasing capacity for more efficient long-haul service at crowded airports, and by diverting a portion of highway trips. This report presents the findings and recommendations of the NMI, a unique interagency cooperative effort of the Federal Railroad Administration (FRA) of the DOT, the USACE, and the DOE, with support from other agencies. The purpose of the report is to recommend future Government action regarding maglev. The recommendation is based on private sector and government information generated during the past 3 years concerning the viability of maglev as an intercity transportation alternative for the United States. The information includes the projected technical and financial performance of maglev in intercity markets in competition with other modes of travel, the anticipated external benefits such as reduction in pollution and congestion in other modes, and other national-level impacts. The report considers the potential of a new United States Maglev (USML) system compared with that of alternatives using existing maglev technology or high-speed rail (HSR). |
