ABSTRACT: This report presents Foster-Miller Maglev system performance results and cost analysis for the Severe Segment Test (SST) stipulated by the government. The route design procedures are described and the resulting SST route geometries are defined for the two sets of requirements on ride quality ("Design Goalā€ and "Minimum Required"). Maglev vehicle performance in terms of speed, acceleration, trip time and power consumption is assessed for each of the two levels of ride quality. The effects of available power and ride quality on the overall system performance are evaluated in a parametric study. Four very severe segments of the SST route are identified for detailed analysis. In these segments, passenger comfort is evaluated using a previously developed multi degree-of-freedom dynamic model which incorporates the guideway geometry, lateral and vertical irregularities and the primary and secondary vehicle suspensions. Detailed cost analyses are presented to assess all capital, depreciation, operating and maintenance costs of the Maglev system for the SST route. At-grade and elevated guideway design options are evaluated to determine their impact on system cost. Based on this work, several conclusions of practical interest are drawn, which include the following: travel times of 2 hr are achievable for the 800 km route; overall capital costs are on the order of $9.11 million per kilometer; and operation and maintenance costs, including depreciation, are on the order of 6.6 cents per passenger-kilometer.
