The hydraulic buffer automatically produces a steady retarding force of such a value that, whatever the speed of impact, the wagon is brought to rest as the buffer-stroke is completed. These buffers also produce a very low recoil. Hydraulic buffers make it possible for the safe speed of impact, to be raised from something over 4 mph to nearly 10 mph. Present-day marshalling yards already work with impact speeds of 10-12 mph and a survey carried out at one hump yard showed that 4 percent of impacts were at speeds of more than 10 mph. Hydraulic buffers also have a part to play in the reduction of shock in trains fitted with continuous brakes.
