NEW SHAPE OF TRANSITION CURVE IN HIGH-SPEED RAILWAY TRACK AND ITS ALIGNING

The quantity called "Track Irregularities" is usually used as basic data and technical inferences are made from it. From the view-point of safety and comfort of traveling, we are requested to decrease the track irregularity especially with regard to high speed railway track. Must first of all grasp the essential meaning of "Track Irregularity" and consequently the next two quantities clearly: (i) difference between geometrically practicable shape and the actual shape of railway track. (ii) difference between physically rational shape and geometrically practicable shape of railway track. These two items are almost self-evident for the straight railway track, but for the curved railway track, especially transition curve, there are many problems yet to be solved.
