The general frame plan of the all-steel car is clearly shown by the
photograph on page 128. As will be seen, the floor framing is made
up of two center longitudinal 6-inch I-beams and two longitudinal 5 x
3-inch steel side angles, extending in one piece from platform-end
sill to platform-end sill. The end sills are angles and are secured to
the side and center sills by cast-steel brackets, and in addition by
steel anti-telescoping plates, which are placed on the under side of
the sills and riveted thereto. The flooring is of galvanized,
corrugated sheet iron, laid across the longitudinal sills and secured
to longitudinal angles by rivets. This corrugated sheet holds the
fireproof cement flooring called "monolith." On top of this latter are
attached longitudinal floor strips for a wearing surface. The platform
flooring is of steel plate covered with rubber matting cemented to the
same. The side and end frame is composed of single and compound posts
made of steel angles or T's and the roof
