  • Simplifying complex rail turnout geometry for computing and converging connections
    Patent number: 11780480
    Abstract: In various embodiments, techniques are provided for determining a connection between a rail turnout and another rail turnout or other rail element by a geometry connection process of rail network design software, by reducing the actual complex geometry of the rail turnout to a simplified arc, which at one end is tangent to the geometry of a connecting element at end of the rail turnout and at the other end is tangent to the geometry of a parent base element of the rail turnout. The simplified arc is utilized instead of the actual complex geometry of the rail turnout by a connection computation engine to determine the connection in the model (e.g., by fitting a connection solution using least squares).
