The residual stress distribution condition of homemade heavy rail U75V are tested by X-ray and impact indentation method. Results shows the stress magnitude order from high to low of heavy rail is the same with two methods: Bottom center, Head middle, Bottom right, Head right, Waist. The relative error of indentation method is higher than the X-ray method. The residual stress on the bottom center of homemade rail is much higher than the import one, whereas the stress on the head center of homemade rail is lower than the import one. The compress residual stress exists on the waist position of both homemade and import heavy rail.
