QUALITY OF RAILS AND MEANS OF GUARANTEEING IT

The revisions of the album of sample sulfur prints appended to UIC leaflet No. 860 for the supply of rails are summarized. Results are reported of the correlation between performance of Thomas steel rails with test results. The object was to develop a single test or group of tests to project performance during the initial acceptance of the rails. These tests show that with Thomas steel rails, there is a specific relationship between the results of the transverse tensile test, the compression test, the turning-by-stages test, the magnetic powder test, the dye penetration test, deep etching and the microscopic determination of silicate inclusions and the liability of the rails to "shelling" (dark patches), horizontal longitudinal cracks and transverse cracks.
