A method for the rehabilitation of the base of a railway line (1) having a horizontal layer (6) of compact material positioned below the tracks (4), the method comprising a step of removing, on both sides of the tracks (4), a continuous longitudinal portion (6a) of the horizontal layer (6) to form a relative continuous longitudinal cavity (11), a step of injecting a resinous material in a fluid form in the longitudinal cavity (11), the resinous material being such as to reconstitute, after hardening, the continuity of the horizontal layer (6) of compact material.
