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 floor includes a bottom frame including two side rails. Each side wall includes a plurality of longitudinally space vertical posts attached at the bottom to the side rail. A metal shear plate with wave form stiffening is welded between each pair of posts and at its bottom edge to the side rail and extends upwardly to a top edge spaced downwardly from the windows and acts as an impact plate to prevent penetration. Exterior cladding for the side wall includes a continuous panel connected along the side under the window and a plurality of end to end sacrificial flexible impact panels connected to the continuous panel by a hinge joint at an upper edge of the impact panels so as to cover the impact plate.
