For train cars to maximize the load size, cars will be fitted with s-shaped plates that drop the load between the wheels. The depressed railcar transition pieces are made from 2 ½ inch A514 steel, a very strong grade of steel that is difficult to form. AT&F proved its ability to form the heavy pieces to tight tolerances and added value in keeping the job domestic. The strength of the part is maximized due to the properties of arches, which lends itself to bigger loads. These larger loads benefit from the depressed seating in that height is shaved off the load, allowing for heavy loaded trains to easily pass through tunnels. AT&F takes pride in pushing the limits of size and scale and delivering quality parts where other fabricators fall short.
