On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.
[0026] Since there were many types of switch machines used in my country's railways in the early years, such as four-wire, five-wire, six-wire, etc., some equipment needs to be replaced. Based on the reuse of turnouts, during the system transition stage, it is necessary to switch the equipment for transition, and the task is large and cumbersome. The method of changing the internal wiring of the switch machine and changing the relay connection cannot be implemented if technical protection is involved. In order to achieve the switch without changing the internal wiring of the turnout control system, the utility model proposes to add a switch between the outdoor cable and the switch machine connector to achieve the reverse switching of the eight-wire turnout control circuit to the five-wire switch machine.

[0029] Please continue to refer to Figure 2 The eight-wire turnout control system uses eight cables to connect with the outdoor trackside equipment. X1 is the common line for fixed and reverse position start; X2 is the reverse position start line; X3 is the fixed position reverse position start line; X4 is the fixed position reverse position start line; X5 is the reverse position fixed position start line; X6 is the reverse position indication line; X7 is the fixed position indication line; and X8 is the indication common line.
