A cutting machine for a railroad rail performs clamping by use of a screw to fasten a catch arm onto a gauge which indicates a cutting position and is fastened onto a railroad rail. The catch frame is connected to a main body block via slide shafts, and a rotating grinding disk saw, driven by an engine mounted on the main body block, is rocked by working a stroke handle to smoothly raise and lower the rotating grinding disk saw within a cut opening to cut the railroad rail crosswise. By varying the cut of the rotating grinding disk saw, frictional resistance to cutting is reduced and the generation of frictional heat is prevented, permitting use of a small-scale engine and improving the accuracy of the cut.
