A vehicle primarily a mass transit vehicle is formed primarily of composite materials which define a roof section and a floor section of two fiber reinforced sheets connected by an integral core and two rigid side wall sections each formed from welded steel or optionally bolted aluminum defining a series of window openings in a row along the side wall section in a ladder shape. The separate sections are connected to a front end cap and a rear end cap. Mountings for the seats are defined as well as conduits through the floor and roof for electrical and fluid connections. Releasable joints of adhesive are provided between the metal rails and the edges of the composite panels.

The invention claimed is: 1. A vehicle comprising:a roof defined by at least one roof section;a floor defined by at least one floor section;two side wall sections each defining a series of window openings in a row along the side wall section;each side wall section comprising an integral substantially rigid metal ladder structure defined by vertical posts and horizontal rails with openings in the ladder structure between at least some of the posts and some of the rails defining the window openings;said at least one roof section comprising a structural member which is generally of inverted channel shape to define a generally horizontal roof portion and two depending cove portions, one on each side of the roof portion;said at least one roof section being formed at least primarily from inner and outer fiber reinforced sheets containing a core material therebetween formed into an integral structure by a resin material therein;said at least one floor section defining a structural member which is generally channel shaped to define a generally horizontal floor portion and two generally upstanding wall portions, one on each side of the floor portion;at least the floor portion of said at least one floor section being formed at least primarily from inner and outer fiber reinforced sheets containing a core material therebetween formed into an integral structure by a resin material therein;a top edge of each wall portion being attached by a respective adhesive structural connection to a bottom rail of the respective one of the side wall sections such that structural loads in the vehicle are communicated between said at least one floor section and the side wall sections through said adhesive structural connections;a bottom edge of each cove portion being attached by a respective adhesive structural connection to a top rail of the respective one of the side wall sections such that structural loads in the vehicle are communicated between the roof section and the side wall sections through the structural connections.
