JR Hokkaido and RTRI have jointly developed the tilting diesel limited express(Series DC283) with a forced steering truck to reduce traveling time between Sapporo and Kushiro. This paper reports on the running test results of this limited express.The results of measurements were as follows; the lateral force can be reduced by employing the forced steering trucks, while the running stability and the axial force of steering link are satisfactory with no problem. The lateral and vertical riding qualities are excellent, the newly developed control servo cylinder can improve the riding comfort. The cold-proof and snow-proof structures work very well.
