Side shiftable railway car
摘要:
A side shiftable railway car in which the bolsters resting on the wheeled trucks engage a movable center plate on the underside of the car. The center plate may be slid sideways along retaining flanges welded to the underside of the car and locked in place by heavy keeper pins adapted to be inserted and extracted manually with levers.
