[0002] With the development of urban rail transit, the operating speed of subway lines has gradually increased, and the frequency of train departures has also increased. For early lines, due to the limitations of turnout technology during the construction period, the passing speed is often low, especially for turnouts with turnaround requirements. The lateral passing speed of the turnout can no longer meet the needs of train departure frequency, and turnout transformation is urgently needed. However, when designing the turnout line type for existing lines, the forward construction method is adopted, and no space for turnout transformation interface is reserved. Therefore, the improvement of turnout performance is subject to many restrictions. Therefore, a turnout line type transformation method is urgently needed to increase the lateral passing speed of the turnout and enhance the turnaround capability of the turnout while considering the limitations of various conditions of the existing lines.
