Abstract: The invention relates to an apparatus for measuring speed of a railway vehicle and method thereof wherein a light source is installed in the vicinity of a track and also a measuring unit is installed on a railway vehicle, thus an actual speed of the railway vehicle running along a track is measured by an indirect measuring method. An apparatus for measuring a speed of a railway vehicle is comprised of a light source installed in the vicinity of a track and emitting a circular beam or a linear beam, a measuring unit installed at the front or back of the train and receiving the light emitted from the light source, and a speed converter for converting a signal received from the measuring unit into a speed value of the train. A method for measuring a speed of a railway vehicle comprises the steps of: controlling size of a continuous beam emitted from a laser unit installed in the vicinity of a track and making a parallel beam, emitting the parallel beam to a measuring unit installed on the train, and measuring a speed of the train utilizing a time reaching a maximum level of the intensity of light.
