摘要： A rail joint for interconnecting two successive rail bars of a railroad track includes longitudinally aligned first and second guide rails. Each of the guide rails has a mounting end adapted to be secured to a respective one of adjacent end portions of the rail bars, a distal end opposite to the mounting end and spaced from the distal end of the other one of the guide rails at an expansible space, and a downwardly and longitudinally extending dovetail projection. A connector is adapted to be fixed on the railroad track and is formed with an upwardly opening and longitudinally extending dovetail groove for receiving fittingly the dovetail projections of the guide rails therein so as to maintain alignment of the guide rails.
