The cross span assembly is a pre-assembled unit consisting of span wires, cross span support wires, and 3 adjustable catenary wire hangers. 2 metal tower masts on bases with mounting screws and slide-on connections are included. The mast spacing can be adjusted up to 235 mm / 9-1/4". The span wires are made of welded steel wire, the cross span support wires are elastic, and the masts and catenary wire hangers are electrically separated from each other. Mast height 150 mm / 5-7/8".

The cross spans are realistic, sturdy, and are all installed in the same manner. The spacing between the metal tower masts is adjustable, as is the position of the catenary wire hangers over the track. The doubled cross span support wires are elastic and are prototypically tensioned as a polygon.
