Abstract (en)
[origin: WO2010127652A1] The invention relates to formwork (1) for producing a railroad tie, wherein the formwork (1) comprises a form cavity into which concrete can be filled for creating the railroad tie, and wherein the topography of the formwork (1) facing the form cavity determines the exterior design of the railroad tie to be produced, designated as a precision concrete component, and wherein the formwork (1) has a precision surface (6) determining the surface of a segment of the railroad tie to be produced to be made with a low tolerance, and wherein the formwork (1) comprises an exterior, strong wall (2), and the precision surface (6) and an area of the topography of the formwork (1) facing the form cavity extending beyond the precision surface is formed by a molded component (5) securely connected to the wall (2).
