Abstract

In a transition rail (1) for the connection of rails having different rail cross sections (2, 3), the transition rail (1) comprises two transition zones (a,c), wherein in a first transition zone (c) the larger-height cross-sectional profile is reshaped to transition into a smaller profile height and in the following, second transition zone (a) the rail foot is worked to match the new profile of the consecutive rail foot. The method for producing the transition rail is characterized in that the transition rail is at first heated and introduced into a press mold, whereupon the rail is reshaped in the web region and pressed in the direction of the profile height, and that the rail foot is mechanically worked following complete reshaping.
