ABSTRACT OF THE DISCLOSURE There is disclosed a drop end for a railway car which is adapted to be manipulated (lifted) from within the car by power equipment to open or close the car end. The car end includes lower side posts, each having a cam follower running in a cam on the car frame which swings the car end when lifted. The car end is swung about a pivot carried on the posts which are guided in a vertical slot cam that cooperates with the swing cam. The car end is opened outwardly of the car and rests in open horizontal position on a pedestal support of the frame so that adjacent open car ends form a bridge to move loads longitudinally of the train. The car end is dampened in lowering (opening) movement by dash-pots connected between the car end and car frame. There is also disclosed a side dumping railway car which tilts the car body to either side by sets of pneumatic cylinders, each set being alternatively under control of a valve; each drop end of the car includes cam members on the exterior that engage a lock-out mechanism inactivating the sets of cylinders for tilting the car body by setting the control valve of both sets of cylinders to exhaust while either end of the car is in open position, i.e., either end is lowered.
