A method and apparatus for transposing a pair of railroad rails. In the embodiment of the invention described below, a self-propelled rail-transposing machine having a pair of rail threader eyes at both the front and rear of the machine is provided, with the two rails being threaded through these four eyes so that they cross beneath the machine. Hydraulic cylinders are preferably included for moving the eyes vertically and horizontally and for individually tilting the threader eyes to twist the rails so that, on double-shoulder tie plates, the rails will come over the shoulder when spikes are pulled only on one side of the rail. Further, a hydraulic clamp and thrust jack is provided on the machine for moving up to a quarter mile or so of a rail along its length in either direction to realign transposed rails having staggered joints.
