It is very important to understand the mechanism of ballasted track deterioration and predict track settlement or track irregularity growth rate for reducing track maintenance costs and designing new track structures. Track site measurements have been carried out to investigate the tendency of track settlement. In order to develop a new simulation model for track settlement, we have to measure track settlement with high accuracy, low cost and low labor. In this study, we described a new method, which can measure the track settlement with a high accuracy of 0.1mm to 0.2mm. This method does not require any expensive devices except for an electric digital level, and a large-scale construction work is not necessary.
