A mobile rail head planing machine comprises a pair of tool carriers vertically adjustably mounted on a machine frame, respective ones of the carriers being associated with a respective track rail. Each tool carrier carries a metal shearing tool engaging with the lateral outside face of the rail head of the respective rail and guide rollers respectively engaging the running faces and lateral outside faces of the rail heads guide each tool carrier along the respective rail. Power-actuated jacks press the guide rollers against the rail head faces they engage for guiding each tool carrier clearance-free along the rails.
