The track structure of new railway lines should be superior to that of the conventional track in terms of construction costs, maintenance costs, environmental preservation and easiness of laying. A low-noise track with removable ties directly-fastened to the concrete roadbed was proposed as one of the cadidates for new lines. To confirm its performance, this track was laid and tested at the Test Site of RTRI and on the Ohsaka kanjou line. Through the tests of this track, we concluded that it has satisfactory performance as a low-maintenance and low-noise track.
