  • This paper presents the performance and test results of propulsion system which is met the requirements of urban MAGLEV. The design of propulsion system should be considered the effect of attractive force by the magnetic levitation and train running resistance. In this paper, the tractive and braking thrust are calculated and the train performance is simulated for the service track. Finally the test results of complete car are shown to verify the performance.

  • Proposed herein is a shape design of a different rail support block with existing ones for the commercialization of the urban maglev. The rail support for existing test lines adopts monoblock steel sleeper, whereas an individual support system has been proposed to achieve an additional cost savings and to provide an emergency exit. Also, to enhance the easiness of installation and the repairability, alignment adjusting methods suitable for the new design have been devised.

  • It leaves much room for improvement that UTM-01 is of practical use. Therefor we will design of UTM-02 system. The design of new magnet is based on light weight for bogie system. We used Maxwell-3D FEM for design of new magnet. The new magnet for UTM-02 that was reduced weight of magnet. 22kg, then it was increased ratio lift to weight is 9.87.

  • In this paper, traction system for urban transit maglev system is proposed. Using vector control strategy to control magnitude and frequency of output voltage transiently is general. But in case of traction system for railway vehicle, it is impossible that adapt vector control because there is one-pulse mode in a high speed region. So this paper proposes the control strategy using vector control in a low speed region and slip frequency control in a high speed region. And also proposes overmodulation method that makes to change in one-pulse mode softly. The performance of traction system will be verified by simulation results using ACSL.

  • According to the Intergovernmental Panel on Climate Change, combustion of petroleum-based and other fossil fuels results in the increasing atmospheric concentrations of $CO_2$ and other greenhouse gases (GHG's) and is a major contributing factor to global warming. This paper includes estimates of the energy and petroleum use and the GHG emissions caused by the transportation sector. It then examines the extent to which diversions to alternative modes may be possible. Estimates are made of the potential reductions in energy and petroleum use and GHG emissions resulting from diversions from conventional modes, to both low-speed urban and high-speed intercity maglev vehicle trips based on "well-to-wheel" (i.e. total-fuel-cycle) calculations.

  • Applications of superconducting technology in transportation is more straightforward than others, such as magnetic levitation (maglev) trains. A maglev train is of high speed & low power-consumption, environmental friendly and safe, accompanied by some drawbacks. This article will introduce the application of superconducting technology in the urban mass transport system, and the bottleneck of this application.
