This paper introduces the performance test of the prototype vehicle which will be in operation for Urban Maglev Program. While common trains with steel wheels use rotary induction motors for propulsion maglev trains gain thrust force from linear induction motors maintaining the constant airgap with levitation electromagnets. Therefore not only the behavior of the linear induction motor should be well understood but also the way of propulsion that minimizes its effect on the levitation system should be took into account. Performance test procedures of maglev trains are proposed and carried out and the characteristics of acceleration and deceleration are verified to agree with the design criteria. Tests are mainly performed on the linear section of the test line and the driving characteristics on the section with a 6‰ incline are examined additionally. As a result the performance of the prototype vehicle in the reverse operation can satisfy the requirement about the acceleration and deceleration 4.0m/s2. And the design modifications of the commercial vehicle and the performance specifications required on the demonstration line are investigated.
