ABSTRACT:
The present invention is directed at an improved device for joining together abutting railway rails between two railway ties. The rails to be joined together have a head portion, a web portion and a toe portion. The joining device includes first and second elongated metal joint bars for holding the abutting ends of the rails together. The joint bars span the ends of the rails and hold the rails together by mounting to the rails. The joint bars are mounted to each rail on opposite sides of the web portions of each rail. The joint bars are configured to mount to the web portions of the rail between the head and toe portion of each rail.
