5A's are semi-peranently coupled like a multiple unit and are joined by bar couplings. The vanilla Mk5's are like standard loco hauled trains, use Dellner couplings and, unlike the 5A's, the carriages can all be coupled & uncoupled at will and anywhere. The 5A's need to be uncoupled at a depot.So what is the big difference?
