An energy absorbing apparatus is provided and includes an outer shell having opposed ends and a left side wall, a right side wall and a hollow core. The shell includes a plurality of longitudinally spaced apart fold points positioned on the left and right side walls only located at a height in the middle region of the shell relative to the height of the left and right side walls. The fold points facilitate a controlled folding up of the left and right side walls and at least part of the shell, at or around, the fold points, during an end on impact.
