Rail Restoration:Rail Repair, Rail Inspection

Rail gauge measurement explained: what the 16 mm measuring plane means, how tool accuracy classes map to line speed, the tolerance bands that apply and the errors to avoid.

Rail grinding acceptance standards demand profile deviations within +0.2 mm. Compare pre-grinding, preventive and corrective grinding - and why precision wheels pass acceptance on every rail.

Explore common rail defects - abrasion, corrugation, fish-scale cracking and more - with treatment limits and practical rail repair solutions that keep your line safe and smooth.

Rail head rollover is a common defect where rail head metal plastically flows and extrudes outward under immense wheel loads, frequently occurring on small-radius curves and switch points.

Rail side wear is a critical defect impacting railway operational safety and costs.

Rail corrugation is a common and complex defect in railway operations, characterized by periodic wave-like irregularities on the rail surface.
