A detection and indication system for use in a railway switch machine which utilizes one or more roller members which physically interact with a point detector bar coupled to one or more switch points to provide an indication of a point failure upon movement of the point detector bar a predetermined distance from an initial position. The system includes a mounting structure structured to be coupled to a housing of the switch machine and a first sensing device coupled to the mounting structure. The first sensing device is positioned and structured to detect movement of the point detector bar a second predetermined distance from the initial position, wherein the second predetermined distance is less than the first predetermined distance.
A method of providing early detection of point failure in a railway switch machine which utilizes one or more primary roller members which physically interact with a point detector bar coupled to one or more switch points to provide an indication of a point failure upon movement of the point detector bar a first predetermined distance from an initial position, the method comprising:
