PLANAR AND ALTIMETRIC LAYOUT OF TRACK APPROACHES TO CURVES ON FAST LINES

I RACCORDI PLANO-ALTIMETRICI PER LE CURVE DELLE LINEE DIRETTISSIME

In order to replace the approach tracks with a constant banking on the existing lines by sinusoidal tracks, which are certainly better, it would be necessary to modify long sections of track. Therefore, a new type of approach track is proposed. They would consist of three sections, of which two end sections would be transitions and the central one would have constant banking. The possibility of superimposition with regard to the cubic parabola is all the higher, the longer is the intermediate section. The proposed approach track arrangement is analyzed in order to permit its application on high-speed lines to be built in the future.
