In order to decrease the lateral force generated in the railway vehicles in the curve sections, a simple steering system for the bolsterless bogie was developed. The mono-link with the actuator function is used, and an appropriate steering force is added to supplement self-steering characteristic of the wheel-sets. The authors have designated this system as an "assist steering system". In this paper, we report the result of fundamental running test in the test line. As a result, it was apparent that the average lateral force in the circular curve section decreased by approximately 30%.
