AT steel rail transformation method

The invention discloses an AT steel rail transformation method which comprises the steps of transforming a 60AT2 steel rail into a first turnout switch rail, wherein the first turnout switch rail is used for replacing a turnout switch rail manufactured by a 43 kg/m common steel rail; and/or transforming the 60AT1 steel rail into a second turnout switch rail, wherein the second turnout switch railis used for replacing a turnout switch rail manufactured by a 50kg/m common steel rail. According to the method for replacing the railway turnout switch rail based on transformation of the AT steel rail, the AT steel rail is adopted for manufacturing the old turnout switch rail, the strength of the switch rail can be improved, manufacturing of the switch rail is simplified, meanwhile, supply is guaranteed, and the economical efficiency is good. 本发明公开了一种AT钢轨的改造方法，该方法包括：将60AT2钢轨改造为第一道岔尖轨，所述第一道岔尖轨用于替换43kg/m普通钢轨制造的道岔尖轨；和/或将60AT1钢轨改造为第二道岔尖轨，所述第二道岔尖轨用于替换50kg/m普通钢轨制造的道岔尖轨。本发明提供了基于AT钢轨的改造用于铁路道岔尖轨替换的方法，采用AT钢轨制造旧型道岔尖轨，可提高尖轨强度，并
