Abstract: A mechanism for coupling a switch point to a point detector box having a point detector bar includes a first portion structured to be slidably coupled to the point detector bar and a second portion structured to be slidably coupled to the switch point.

Abstract: A point detector device for use in detecting the position of a switch point in a railway system includes a frame and a point detector bar slidably coupled to the frame. The point detector bar is structured to be selectively coupled to the switch point of the railway system. The point detector device further includes a number of sensors coupled to the frame, the number of sensors being adapted to detect the position of the point detector bar with respect to the frame. The frame includes a coupling mechanism structured to rigidly couple the frame to a fixed rail of the railway system.

Abstract: A point detection system is provided for use in a typical switch machine with a typical indication system, wherein a point detector bar is slidably captivated within a point detector sleeve, and wherein a target that is integrally engaged with the point detector bar is sensed by at least one sensing device, thereby to detect movement of the point detector bar. The point detector sleeve is supported by a track side bearing affixed to a track side wall of the switch machine, and by a field side bearing affixed to an opposing wall of the switch machine. The point detector bar extends outside the switch machine from only the track side bearing, thereby eliminating the bearings and the pinch point between the hand throw lever and the two piece point detector bar that otherwise extended from the related art switch machine. The sensing device may be mounted upon a slide mechanism to adjust the sensing device relative to the target.

Abstract: An empty/load mechanism for controlling the brake pressure on a railroad car is mounted inboard on the web of the car body side sill having a lower flange. A pivotable sensing arm reaches around the side sill flange and has a horizontal contact shaft at its free end for contact with the upper surface of a truck side frame for operating the mechanism in response to the distance between the car body and the truck.
