I guess my needle beams will lack truss rods per the discussion Doug pointed out above. I  may include some tie rods along the outside face of the center sills and terminating on either side of the buffer plates as Jim suggests.

I just gotta ask....  

Why are Needle Beams fitted if the Tension Rods don't go through them(thus forming a shallow truss)?  There appears to be no need for them if they aren't housing rods; spacer blocks(crosswise) would be used between the Stringers, for horizontal tension rods.
