Abstract of the Disclosure In a trailer train combination having a tractor, lead trailer and one or two more following trailers, an adjustable dolly under the front end of each following trailer provides for close coupling of the multiple trailers in end to end contact. When the multiple trailers are lifted to inclined position the upper trailer or trailers discharge their flowable contents out through the lower trailer in a self unloading operation. The dolly has a slidable fifth wheel assembly and self steering ground wheels which may be locked in straight forward positions. A cab controlled electric and pneumatic control system controls these and other functions in the dolly. The trailers may be equipped with walking floors for self unloading in level positions.
