抄録

Up to this time, we have tacitly assumed in the theory to reduce the shape of Transition Curve that a particle as a center of gravity of a car runs along the center-line of railway track and at the same time contacts with the surface of it.<BR>However, actually, the car moves in plan along the locus which the middle point of the chord linking two bogie-centers of a car traces, and on the other hand runs in elevation along the curve which is fairly biased to the inside of the curve of the center-line of railway track, on account of the existence of a Cant in the Track. Therefore we must treat the center-line of railway track and the locus described by the center of gravity of a car as a different line and must investigate, in the research about the shape of Transition Curve, the shape of center-line of railway track which enables the center of gravity of a car to move smoothly.
