Abstract
Abstract Three vertically freely movable rail sensor bogies are spaced apart in the direction of track elongation on a survey car frame supported on undercarriages for movement on the track. Two transducers are associated with the three bodies for converting any relative movement of the rail sensors in respect to each other into an electrical error signal proportional to the relative movement, each transducer being connected to the intermediate bogie and with a respective one of the other survey bogies. A recorder is connected to the transducers for indicating the error signals.
