Abstract
A train position control arm adapted for use in handling cars of a unit train in a movable train positioner and in a stationary train holder. The arm is proportioned to engage a car coupler from a zone limited to the area immediately above the coupler so that a symmetrical pair of such arms may be simultaneously employed at the same location on a mating pair of couplers. A coupler engaging head of the arm includes elements for engaging and disengaging a coupler under full compression or buff loading. In a train holder apparatus, the arm is pivotally supported on a horizontal axis spaced from the tracks and at substantially the same height as a car coupler. A stationary base supporting the arm includes shock absorbing apparatus adapted to resist impact forces on the arm along a line coincident with the pivot axis.
