摘要： 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. Use of the sensing device eliminates the need for cams to monitor in order to detect movement of the point detector bar, as well as eliminates moving parts between the cams and the mechanical linkages. Further, at least one other sensing device detects a normal and reverse locked position of a lock bar assembly and lock box of the switch machine.

摘要： 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.
