Abstract
A spiker vehicle and associated method of spiking apply a line of laser light which is reflected from a tie plate and imaged by a CCD camera connected to a computer programmed for image recognition by simultaneously determining the locations of two spike holes in the tie plate and the edge(s) of the tie plate, which spike holes are offset in the rail direction. A first spiker is mounted to a carriage which is moved automatically until the first spiker is over one of the sensed holes. The laser and camera are mounted to the spiker for rail direction movement therewith. A second spiker may be mounted to the carriage for spiking spike holes on the opposite side of the rail from the first spiker.
