  • Process for modifying the section of a railway rail and rail thus obtained
    Patent number: 5611234
    Abstract: The process consists in increasing the height of the rail to the detriment of the thickness of the web (16) and of the flange (18). Firstly, the thickness of the upper part of the web (16) below the head (14) is reduced by machining and, next, the rest of the web (16) and the flange (18) of the rail (10) are heated up and deformed by forging. This process avoids hardness modifications of the running surface of the rail.
