| Abstract: | The horizontal alignment of new built railway was expressed by chained list made of straight lines, arcs and transition curves. Calculation method of transverse distance error from structure center to horizontal alignment was studied. Simulating for straight line and arc by least square method, calculating transition curve linking straight line and arc, then a new horizontal alignment chained list was simulated. |

| Keywords: | transverse distance error least square method simulation for horizontal alignment |
