ABSTRACT OF THE DISCLOSURE Mobile apparatus for, on site, welding of rail retaining clip studs to existing railroad rail plates which includes a railway car assembly having wheel and axle assemblies and propulsion means to move the railway car assem- bly along the railway tracks. The railway car assembly further includes two carriage assemblies each of which carries two welding gun assemblies which project downwardly upon each side of the rail plate. The carriage assembly includes carriage actuator means for moving the carriage assembly both longi- tudinally and transversely of the rail plate to position the welding gun assemblies. A position and sensing control means is provided which includes a rail plate sensor which first senses the position of a rail plate to stop the railway car assembly and properly position the welding gun assemblies with respect to the rail plate longitudinally thereof. The position sensing and control means further includes a rail web sensor which senses and positions the welding gun assemblies transversely of the rail in proper position.
