This paper presents the design and implementation of an improved re-adhesion control system for the Korean High-Speed Railway. This system provides an improvement of adhesion characteristics regardless of the severity of wheel slip under a continuous slipping rail condition by blending two conventional control algorithms and acceleration control scheme. To verify the validity of the proposed hybrid control scheme, the downscaled re-adhesion control simulator was set up. The running tests under conditions very close to the state of the KHSR were performed. Compared with an individual operation of the conventional control scheme, the proposed re-adhesion control scheme shows a superior ability to reduce wheel slip and the vehicle vibration accompanied by the re-adhesion control. It can be said from this result that the proposed control has the advantages of reducing wheel abrasion and improving tractive performance. Therefore it can be expected that the proposed control scheme may be applied to the high-performance vehicle.
