JR Hokkaido and RTRI have jointly developed the tilting diesel limited express(Series DC283) to reduce traveling time between Sapporo and Kushiro. The newly developed tilt-truck for this DC283 has such various features as a wheelset steering linkage connected with bogie angle, 1900mm low tilt center height to improve the running performance, a low-cost air-cylinder with a high response servo-valve to improve riding comfort and counter measures for low-temperature and heavy snow, etc. So far, we executed its performance tests and proved that the newly developed forced-steering tilt-truck can be put to practical use. In this paper, these features of the forced-steering tilt-truck are described.
