Development of Railway rail used in Japan (1872-1930's) is traced by verifying the rolled mark and the cross-section of individual rails remaining in various forms and in various places. In this 2nd report, rails used by railways other than the national railways are described: rails of private railways, tram rails, light rails, imported used rails and others. Most of these were imported from overseas until 1920's: from U.S.A., U. K., Germany, Belgium and other countries. As for cross-sectional design, the American practice had been widely accepted until the Japanese original sections 40N, 50N and 50T were proposed and adopted as the standard in 1961.
