Abstract: A plurality of sub-assemblies comprising elements of a transit vehicle are first completed individually in their respective jigs. Each of selected ones of these sub-assemblies has embodied therein an extrusion having a trackway formed thereon for alignment with a selected conveyor way provided therefor in a collector, which travels in successive cycles along a selected path on a final assembly floor. Each of said selected sub-assemblies has joint means formed thereon for interlocking engagement with complementary joint means provided on one or more of the other sub-assemblies. The selected sub-assemblies are conveyed, by means of their trackways riding along their respective conveyor ways, into the collector, and thus into interlocked relation with each other in positions of final assembly therein, where they are secured permanently in such interlocked relation. Other sub-assemblies are then added to produce a complete transit vehicle.
