This study develops a railway bridge deflection-track irregularity transformation program for the deflection estimation method based on onboard-measured track irregularities. The program can investigate the effect of the adjacent bridge deflections on the track irregularities of the target bridge. A numerical calculation for 7 consecutive bridges of 13 m beams clarifies that the waveform of track irregularity becomes steady from the third to the sixth bridge in the running direction.
