Abstract
A public transit vehicle has a vehicle body having a roof defining an interior ceiling surface, two side walls each extending longitudinally of the vehicle including an upper side wall portion connecting to the roof and a row of windows underneath the upper portion, a central aisle and two rows of seats each on a respective side of the aisle and along the side wall at the windows. The roof and floor are formed from a welded frame structure over which is applied a molded panel formed in single panel structure and bonded to the frame structure. The panel is formed by molding a sandwich using a thermosetting resin through top and bottom fiber reinforced sheets and a honeycomb layer of resin impregnated paper and foam between the sheets. The floor panel is shaped so that its thickness varies and its top and bottom surfaces deviate from an otherwise planar structure to incline downwardly at a door way and to incline upwardly to clear structural elements. The side walls are clad by a coping panel connected to the roof panel and by a side wall panel beneath the windows. The cladding panels carry the wall insulation.
