Abstract (en)
An arrangement for determining the speed of a rail vehicle (2) moving along a track (3) with rails (4, 5) resting on sleepers (6) mutually separated by a distance (d) known comprises a sensor (7) sensing vertical oscillations of the vehicle. A processing member (10) is treating measuring signals obtained by the sensor for determining the frequency of oscillations therein emanating from passages of sleepers by a wheel set (20) of the vehicle. A calculating unit (11) multiplies the frequency determined by the processing member by the distance (d) between adjacent sleepers for determining the speed of the vehicle.
