The load of a maglev train, which is being considered a future transportation, is uniformly loaded on a levitated surface of a rail unlike a typical train because the maglev train is magnetically levitated and propelled. In addition, the driving performance is superior since the maglev train doesn't directly contact the railway. A integrated track system, to which a sleeper is installed toward a longitudinal direction instead of a perpendicular direction, is suggested, considering this loading characteristic. The longitudinal sleeper of this system is expected to contribute to stiffness increase of a bridge and weight-reduction of a girder. In this study, the structural characteristics of proposed and typical systems have been numerically compared and analyzed. In addition, the improvement of the integrated system has been proposed.

The load of a magnetic railway is uniformly loaded on a levitated surface of the rail. So it is advantageous for noise and vibration compared to the typical railway systems. But for ensuring driving stability and ride-quality, regulation about the gap of rail is stricter than the typical railway. In this study, the impact of bracket, which can control the gap of rail at the integrated track system, have numerically been performed. Also, the effect of interval of the bracket installed in the longitudinal direction of the integrated track system, which consist of girder, bracket, sub rail and levitated rail, have been compared and analyzed. Through this, applicability of the bracket structure for integrated track system have been identified.
