This listing is for one O gauge track repair pliers tool, specifically hand redesigned pliers to help repair O gauge track. Over time tubular track can loosen, expand or separate easily when repetitively assembled and disassembled. Pins can also fall out over time. What these pliers can do is tighten pins snugly and close the tubes down without deforming the rails. These pliers will work well on Lionel, and other manufacturers of tubular O gauge track of the same diameter. But, will not work on 0-27. See the second photo of how to apply the pliers to the track to reform. The second and third photos are the before and the last photo is the after. This is showing reforming without the track pins but can be used to form track with pin also. Each pair is hand crafted. Track not included. CAN ALSO BE USED ON STANDARD GAUGE TRACK.
