In the former paper, we reported on the development of a new experimental apparatus "Ride Comfort Simulator". It has a mock passenger room furnished with 12 seats mounted on a 6-axis motion base. As vibration, noise, temperature, landscape scenery and lighting are able to be controlled individually, this simulator has made it possible to evaluate the relationship between comfort/discomfort of passengers and various environmental factors. In this paper, we introduce some experiments using this simulator including : the interactive effect of noise and vibration, optimal working spaces for using a PC on a moving train, the relationship between momentary lateral vehicle motion and the postural stability of walking/standing passengers and the utility of handrails and straps on commuter trains. To conclude, we have referred to the effectiveness of conducting experiments using such simulators.
