The ballast packing machine illustrated, designed by August Scheuchzer, is claimed to permit even packing without crushing the stones. It is carried on a four-wheel frame and is operated by a 45 h.p. petrol motor, with a four-speed gearbox providing forward and reverse speeds varying from 4 to 28 m.p.h. The packing device is a pair of vibrating tool frames, which is illustrated. The tool is automatic, and depends on the amount of resistance of the packed ballast to release the packing mechanism of the tool.
