The Korea is consisted of 70% mountain terrain and at existing railroad, which is many of curve railroad segment naturally. The tilting train cancels centrifugal force of the curve railroad segment at sway and need not decelerate speed of tilting train in the curve railroad segment by the tilting of train body. As you get a hunch as term "tilting", the biggest advantage of tilting train is that the train body is tilted when the tilting train is driven. The TTX which is Korean tilting train is acquired tilting angle range from -8° to maximum 8° and can get high speed at railroad which shared with low speed train. But the tilting of passenger compartment gives negative influence by decreasing ride comfort. Presently, the measuring method of train ride comfort is mainly based of vibration, that is, mechanical parameter. This paper would like to show the ride comfort using the biological parameter by measuring R-R interval (Peak to Peak Interval) of ECG(Electrocardiogram), event number and measuring the event area of GSR(Garvanic Skin Response), the number of zero-crossing and magnitude of EMG (Electromyogram) of Human Model. This method is more direct, based on human body response, than mechanical parameter method. In this experiment, we are supposed to know excitement, awakening, muscle fatigue, through examining bio-signals. Considering pleasance and stability, elements of ride comfort, the pleasance is restricted thoroughly and our research will just only think aspect of stability. The research about ride comfort of TTX ultimately must make advance ride comfort of TTX.
