The external fittings on coaches were, after the earlier years of the railways, fairly standard so that new coaches could work with older ones and coaches moving between different railways could be connected together if required. Some of the detail from the coach ends is reproduced below. Although modern coaches were fitted with automatic couplers, coaches needed to have a coupling hook for use with older, non-automatic coupling-fitted stock, and the end coach of a rake needed to have a coupling hook for use with the locos, which were fitted with screw link couplings. The solution to this was to have a fitment that combined the older coupling hook and the more modern automatic coupler, all in one unit.
With screw link couplings the buffers are held tightly together. This avoids the posibility of the motion of the train making the coaches move in relation to each other which would be both dangerous and most unpleasant for the passengers.
