Abstract
A track recording vehicle for detecting the resilience of a rail track has a machine frame supported on two rail-mounted undercarriages. A first measuring system detects a vertical distance of the rail track under load and a second measuring system detects a vertical distance of the rail track under no load or with reduced load. The first measuring system is coupled to an evaluation device for calculating the course of a first vertical sine and the second measuring system determines a course of a second vertical sine, relative to a common reference base defined by two outer measuring points under load, at an interposed central measuring point without or with reduced load. The evaluation device calculates a subsidence of the rail track under load from the two vertical sines. The track recording vehicle detects a subsidence of the rail track under load in a single measuring run.
