Used in pairs. Sold separately. Use both an inside and an outside rerailer.
An old and reliable design for two-way rerailing of locomotives and heavy freight cars. Cast-steel rerailers straddle two ties and hook to rail head. Stout carrying handles at each end butt up against side of ties to keep rerailers from sliding as wheel mounts the ramp. No wedges or spiking needed ... just scrape some gravel away from the ties and hook the rerailers to the rail. Ready for action.
