Few buffers function completely except in the case of wagons, because the impact force passes to the frames through the medium of the buffers, and the design of a buffer that will modify the stress transmitted satisfactorily is a constantly recurring problem. Several buffers are illustrated, including a buffer with compound springs to give a soft response, a collision-type buffer, a hinged buffer for the front end of a locomotive fitted with a cowcatcher, and an emergency drawbar for diesel-electric railcars. By using a combination of steel and rubber springs a relatively high shock capacity is obtainable with consequent advantages to passengers, or goods, and rolling stock. The position of the buffer and coupling unit at the centre of the headstocks assists greatly towards obtaining a small deflection which the frame structure as a unit would otherwise be called on to provide. The flexibility of the coupler on curves has been proved beyond question by the reduced wear of tires and axle journals of vehicle so fitted.
