While in the modification illustrated in the drawings the link rods 14L are arranged outside of the wagon body, they might also be arranged within same and in that case the slots 13 and 19 might be dispensed with- Alternatively these linksmight also be bent"; so as to avoid} the necessity of providing slots 19. In order to 'be able to discharge several wagons of a train of waigons' atz a tiine, the shafts 4 of adjoining wagons may be provided with coupling means, whielrma-y be of-a pneumaticor electric kind so that by displac:
