Abstract of the Disclosure A system for orientating a railway spike of the type having a head provided with a lip which projects at one location from the head. It is important to ensure that the lip is aligned in a predetermined angular position so that when the spike is driven in a tie by means of an automatic spike driver the lip will overlie the rail flange. The system involves holding means, such as an electromagnet for holding a spike and means rotating the holding means and spike until a light path defined between a stationary source and detector is interrupted by the lip of the spike at which point the rotating means, for example, an electric motor is deenergized. Alternatively, deenergization of the motor does not occur until, in addition to detection by the light beam of the lip position, a switch indicating a complete 90° rotation of the spike is also activated so that one of the flat faces of the square section shank will face the rail.
