The invention discloses a railway track laying machine capable of moving transversely to step over a railway line under loads, and belongs to the field of railway construction equipment. Two groups of four walking mechanisms are arranged symmetrical about the center of a main rack to be fixedly connected with a horizontal longitudinal beam of the main rack through outer walking transverse beams of the walking mechanisms. Two groups of four transverse moving mechanisms are fixedly connected with the horizontal longitudinal beam of the main rack through outer transverse beams of the transverse moving mechanisms. Inner transverse beams of the transverse moving mechanisms are in sliding fit with the outer transverse beams and move transversely in a stretching and contracting mode relative to the outer transverse beams through stretching and contracting movement of transverse moving oil cylinders arranged in the inner transverse beams, so that the main rack and the outer transverse beams stretch and contact to move transversely to step over the railway line. Inner walking transverse beams of the walking mechanisms are in sliding fit with the outer walking transverse beams and move transversely in a stretching and contracting mode relative to the outer walking transverse beams through stretching and contracting movement of horizontal oil cylinders arranged in the inner walking transverse beams, and the walking mechanisms walk through walking crawler belts. In this way, the railway track laying machine can directly step over the railway line under loads through the walking mechanisms to perform track laying in a complex terrain, the walking mechanisms and the transverse moving mechanisms can be flexibly switched, and therefore the railway track laying machine completes track laying comprehensively with the function of moving transversely to step over the railway line under loads and improves the working efficiency of track laying.
