A system for detecting the presence of objects, the relative movement between a vehicle provided on a rail track and other objects such as other railway vehicles, the speed of rail vehicles or the presence of stationary obstructions. The system having a signal emission source mountable to the railway vehicle for generating an optical signal, a signal detector mountable to the railway vehicle for receiving optical signal reflected from the other objects, and a processor operatively connected to the detector for interpreting the reflected optical signal to detect the presence of and/or relative movement between the railway vehicle and the other objects. The other object may include one or more stationary markers placed wayside of the rail track, such that reflected optical signals from the wayside markers are interpreted by the processor to provide the velocity of the railway vehicle.
